The benefits of using AJAX technology to create interactive web applications

Article by Eddie Yu

Many advances in web technology have surfaced over the past decade many of which have helped web entrepreneurs and their respective businesses tremendously. One of the newer technologies on the market, made available around late 2005, is the Ajax system.

Technically, Ajax isn’t any type of new software program. Ajax is a form of web development that works as a practice of sorts instead of being an object. Basically, users employ several various pre-existing technologies and together it forms Ajax a term coined by Jesse James Garret.

Ajax is made up of Extensible Hypertext Markup Language (XHTML) and Cascading Style Sheets (CSS). Other technologies like Document Object Model (DOM) and Extensible Markup Language (XML) are also utilized with Ajax. Together, these technologies create one of the most effective web application tools in use today. Explaining everything that Ajax is made up of is extremely complicated. However, using the Ajax method for beneficial web applications is simple enough with some basic knowledge of programming language and other aspects of Internet software.

The benefits of Ajax are hard to quantify. Mostly, these benefits work in the area of cost-containment. Dollars and cents definitely matter in business, and by using Ajax for interactive web applications, a lot of money can be saved over the long haul.

It all starts with the time invested. With Ajax, data transfer takes place at a much faster pace. Using Ajax properly with web applications means faster-loading pages, less crashes, and all-around movement that’s more fluid while working online. The method also has the potential to drastically cut down on time completing a particular task.

As your business grows, more bandwidth is going to cost more money. Bigger businesses need to invest in larger-capacity connections and even new hardware for greater server loads. Repetitive tasks can chew through bandwidth quickly, so Ajax’s ability to reduce repetition means money saved through less bandwidth consumed.Other benefits of Ajax aren’t so easily measured.

Using Ajax, a business’ interface can be streamlined and offer advantage in many areas. Ajax reduces the number of steps needed to complete a task and also reduces opportunities for error. Fewer errors means less time and money invested in manually correcting them.

With web-based applications, there’s also a lot of money to be saved in the long run compared to desktop applications. Offering web applications with familiar and/or easy-to-use interfaces means more productivity and fewer errors to contend with.

Applications of Dedicated Server

Article by Dhruv Patel

Website hosting is necessary for connecting the site with the internet and for accessing the site from anywhere in the world. Server is the first and pre required object for hosting the website and the service of the website depends on the quality of the server. If you want to host an ecommerce website, then the designated server may serve the main purposes of the website and also will ensure the best security.

Dedicated server is one of the effective conception for hosting the ecommerce and large websites. Almost all the hosting companies create their accounts on the specific shared server. A single hard drive and memory device may be used for hosting several websites and the bandwidth also may be divided among the sites. It will be better if you can arrange a single hard drive for storing your single site. You must get the promoted bandwidth and the security with best. A dedicated server maybe defined as the single server for storing a single website and no other sites will be hosted in that machine. Dedicated serve ensures better security and flexible bandwidth.

Dedicated server has some features those are very essential for the website in different purposes. Server security, data transfer, space, software facility and control panel are some of the features of dedicated server. For having those features, most of the clients prefer the dedicated server as the best server.

Security of the website is now one of the main concerns in the present period and dedicated server ensures the best security. To get the access in the server some dishonest person buy hosting in the server and tries to execute some programs those may be harmful for the server security. Some mistakes may be occurred in shared machine and complex to manage everything. Only one webmaster handles the server and there has a little probability of unauthorized access. Some famous websites like Facebook, Google andYahoo are hosted in their dedicated servers.

The data storage space may be changed and extended according to your needs and algorithms may be applied for utilizing the space effectively. You can assign enough bandwidth and different types of data may be stored separately. For transferring data at the satisfactory speed, dedicated server is effective. Some techniques are applied to divide the time of server response in shared server where dedicated servers have no such types of problems.

In the shared based server, you are given the limited of access and few options in the control panel. Dedicated server gives the control panel with the best features and options ensuring the best control on the server. Dedicated server permits to execute more software and features in different purposes. They are easier to control, operate and maintain. There are also some disadvantages of dedicated server. This server is expensive and space becomes unused sometimes. For a single website, you have to keep one administrator and a single server. Though they are expensive but have lot of advantages. They are very essential in some purposes like the sites those have the feature of financial transaction. E-banking and online transaction supportive sites are some of the application of dedicated server.

SQL Server Applications

Article by Ben

http://www.karmatechnologies.co.uk/accesssql.htm”>SQL server applications are generally used as the backend when designing a software application. They are widely used in n-tier application models, as they improve execution and increase scalability. A SQL server application is nothing but a database system that will contain records within tables and upon which various computational operations can be performed. Some examples of SQL server applications include Oracle, Microsoft SQL Server, MySQL, Sybase, and so on.

With so many SQL server applications available in market today, selecting a desired application that satisfies all requirements could be a judicious decision. Among other factors like performance, stability, installation, and maintenance, cost is also a very significant factor, as it directly affects the licensing issues. At an enterprise level it becomes very important to analyse SQL server applications based on the above parameters. Of all the SQL server applications, Oracle is considered to be most widely used, as it is easy to maintain and is more powerful than other applications. Similar is the case with SQL Sever. MySQL is available free, however, its capabilities are not as extensible as Oracle and SQL Server. MySQL, hence is only used for small to medium sized enterprise applications. SQL Server from Microsoft is also among the widely used SQL server applications, however, Oracle outperforms it. Between SQL Server and MySQL for small to medium sized applications, MySQL lags behind, as SQL Server comes with a native support for.NET which makes implementation simpler.

While it may be difficult to rank SQL server applications based on their performance benchmark, Oracle undoubtedly takes the first place followed by SQL Server 2000. In the price/performance ratio factor, SQL Server 2000 overtakes Oracle, as the licensing for SQL Server 2000 comes at 25% of that of Oracle. However, SQL Server is not cross platform compatible like Oracle and MySQL. Though SQL server applications should support relational database management, MySQL does not fully offer relational database management, as it does not support foreign key control. Oracle and SQL Server, on the other hand are fully relational databases that affect storage and retrieval of data, and its integrity. In terms of the language that these SQL server applications use, Transact SQL is considered to have ease of use and understanding. PL/SQL is among the most powerful query language, however, it is a little difficult to use that T-SQL. The language that MySQL uses is considered to be the most difficult and is not as powerful as other query languages.

Other important criteria for SQL server applications could be backup and restore operations, number of simultaneous connections it can handle, security issues, and so on.

Session Domestic Trade Fair Opened On The 25th Of More Than 300 Enterprise Applications – Fair,
Fair first official “test the water” and domestic trade, arrange domestic and export business buyers docking, is a major feature of this Canton Fair. Conference revealed that two dedicated domestic and foreign trade fairs Session scheduled for April 25.

Deputy Director Foreign Trade Department of Commerce, the Canton Fair Business Office main Ren Wenzhong Liang in response to a question that future work in this area will be targeted to enhance, explore the side of the pilot side edge forward.

“Butt this year, two activities that are export business and trade enterprises welcome the extent of beyond our imagination.” Fuminaka Leung said a few days ago to enroll more than 300 export companies and domestic large-scale trade enterprises also more than 100, due to the size and site effects, can not accept new applications, otherwise the data will be a breakthrough.

Wenzhong, Liang said, the last domestic buyers have to be organized, but no arrangements with domestic buyers are interested in the ability to encourage the export of domestic enterprises docking. Through this opportunity, the domestic dealers have also seen opportunities. This work just for a second year, the Canton Fair will continue to explore the basis of this advance.

Decline narrowed day by day from the next day
Fair Deputy Secretary-General, introduced spokesman Mu Xinhai, although the trade fair to be a number of overseas buyers and the total export turnover showed a decline, but the decline narrowed day by day starting from the next day.

Such as 15, the cumulative decline to be 6.3%, turnover decreased by 16.5%. 16 to 19, the accumulated total will decrease the number of daily reduced from 6.9% to 5.4%, narrowed 1.5 percentage points; total daily turnover fell from 26.3% down to 20.8%, narrowed 5.5 percentage points.

Europe and the United States decline by 16.6% against Argentina
Mu Xinhai said, this one pairs of export turnover in traditional markets decline, the export turnover in emerging markets rise or fall.

Total export turnover in the top ten countries (regions) in the European Union, Japan, Australia, the United States four traditional markets dropped 38.6%, respectively, 36.5%, 11.2% and 4.9%. Emerging markets, Argentina, India and ASEAN grew 16.6%, 9.7% and 4.5%, Russia, Brazil, the Middle East were down 42.6%, 35.1% and 7.3%.

Large one smaller one short one long single change
Unilaterally in enterprise access, small single significantly increased the short one. Overseas buyers will be a long single to short more than one large unit to small orders, most of the decline in turnover of goods on display category.

Such as Ningbo Oaks home company exports to Spain
Air conditioning The order amount from the previous by a one million U.S. dollars for the current 20 million, delivery time from 3 months to 2 months; German buyers only previous current amount of each order of 1 / 10 .

Addition to the other bathroom in “or
” It is noteworthy that nine of the ten categories of display categories of export turnover of goods down. Which, in addition to sanitary equipment export turnover increased slightly by 0.7%, and the remaining nine categories were more than double-digit decline in export turnover.

Mu Xinhai said Home Appliances Products traded in a 4.75 billion U.S. dollars, has declined 12.1%, but exports are still mechanical and electrical class ranking.

Guangdong Fell below the national level
It is reported that Guangdong (Guangdong trade mission that the Guangzhou Trade Delegation
Shenzhen

Trading Group) export turnover fell below the national average. Guangdong’s export turnover of 5.03 billion U.S. dollars, accounting for 38.6%; drop of 10%, lower than the national average of 10.8 percentage points.

Possible Applications of Advantage Database Server for Visual FoxPro Developers

Summary:

In our last article, we described our first contact with Advantage Database Server and how we now use it to enable us offer a Client/Server version of our application. In this article, we will explore other possible areas in which you can effectively apply Advantage Database Server as a Visual FoxPro developer.

Introduction:

The Guys at Advantage Database Server have been pitching Advantage to the Visual FoxPro Community for several years now. Some of us who have embraced Advantage as a data store find that as a native ISAM database engine with close compatibility to Visual FoxPro databases, we can apply Advantage Database server in several ways. Using Advantage Database Server has many advantages to the Visual FoxPro developer. This article is a summary of the different ways we have found that we can apply and utilize Advantage with our Visual FoxPro projects. The sub sections that follow will explore the various ways in which Advantage Database Server can be applied.

The Advantage ODBC Driver for Visual FoxPro:

If you have applications that have been accessing your Visual FoxPro database through ODBC, you will quickly find that a major problem is that the existing VFP ODBC Driver (the last one shipped with VFP 6) will not work with VFP 9 if you use any of the new VFP 9 data types that do not exist in VFP 6. The Advantage ODBC Driver is completely compatible with VFP 9.

Before you can use the Advantage ODBC Driver, you must install Advantage Database Server or Advantage Local Server – the ODBC Driver always tries to link to an Advantage Database Server instance. Luckily for us, the guys at Advantage were very helpful, picking a quick interest in us from the very first time we downloaded the product.  They quickly sent us keys to work with a trial version. As soon as the product was installed, we used DBCConvert.Prg utility freely supplied by Advantage to create an Advantage Data Dictionary (.add) – an Advantage version of the VFP .DBC file we were using. The database conversion utility creates the .add file leaving your .dbc file unchanged so that your existing VFP app will keep using the VFP Database through the .dbc file while any other clients (including our Crystal Reports) can get at the VFP Database through our Advantage Data Dictionary (.add) file.

These clients can include any software that consumes VFP data by means of ODBC. In our case, these included applications written in VB 6 that were integrated with our VFP Project – these used the VFP data by means of ODBC while our VFP application was still on the VFP 6 Code base. For the time being, the problem of unfettered access to our VFP data was resolved, albeit temporarily since the version of Advantage we were using was a trial version with a fixed expiry date. If you want to try out the Advantage ODBC Driver, follow these steps:

Ensure that you have either Advantage Database Server (ADS) or Advantage Local Server (ALS) with a valid key and the ODBC Driver (adsodbc.exe) installer packages downloaded from the Advantage Web Site (http://devzone.advantagedatabase.com/dz/content.aspx?key=20)
Install your Advantage Database Server to a windows Server somewhere on your network (or if you want to install a local version on your XP or Vista, this is also possible). In our case, we installed our Software on a computer running Windows 7.
Double-click the file adswin_x86_32 (this is 32-bit ADS. The 64 bit ads is the same but ends with 64). Follow the instructions of the installer to have ADS installed. You will find that the installer runs fairly quickly.
Now double-click the file adsodbc.exe to install your ODBC driver. The ODBC Driver will prompt you for an instance of ADS. Point to your instance of ADS. Even though the ADS documentation says that the file DBCConvert.Prg will be installed when you install the ODBC Driver, we found that it is installed when you install the Advantage OLE DB Driver, not the ODBC Driver. The OLE DB Driver is named oledb.exe. The DBCConvert.Prg is installed in the same folder where the OLE DB driver is installed to. This utility program is written in Visual FoxPro and you will need to run it from within VFP. With these files installed, you are now ready to convert your VFP database (.dbc) file.
Start VFP. Ensure that the VFP .dbc file you want to convert is closed and is not in use either through a Client program or through the VFP IDE.

In the VFP Command window, you may now type DO DBCConvert.Prg. If V FP returns an error message saying that the file does not exist, then you will either have to copy the file DBCConvert.Prg to the VFP Program folder or you will have to use SET DEFAULT/SET PATH so that VFP will search for and find the file. The Open dialog box displays, prompting you to open the VFP Database you want to convert

Select the required database file from the  Open dialog box and then choose Ok. The utility begins generating the new .add file. The file has the same name as your Visual FoxPro database but with the .add file name extension. The .add file is created in the same folder where your .dbc file is located. You will also find the Advantage tables (.adt) files that report the results of the upgrade including FieldUpgradeResults.adt, TableUpgradeResults.adt, RelationsUpgradeResults.adt, ViewUpgradeResults.adt.
You can now create an ODBC Connection in Control Panel by means of the ODBC Administrator using the Advantage ODBC Driver.
You can now make any client applications you write consume your VFP Data using the usual ODBC Connection Information. For example, when you create connection strings in Visual Basic, you can use syntax like ‘strConn = “DSN=MYODBCCONN”‘ and then pass this to your Ado data Connection Object.

Offering a Client-Server Version of your application

Most Visual FoxPro developers are usually accustomed to building complete data management applications (program and database storage) using Visual FoxPro. However, the rigor required of today’s enterprise applications often demand increased storage, strong security, performance and compliance with industry standards. Advantage Database Server can be a natural choice as a Client-Server database engine for Visual FoxPro developers. To begin,  with, Advantage offers extensive support Visual FoxPro table formats and offers tools to access that data. But most compelling is the fact that ADS is also a fast ISAM Remote Client-Server Database Engine.

The objective would be to run your existing Visual FoxPro applications written for a Visual FoxPro database unchanged against an ADS Data Store with little or no code re-writes. You would have to create an ADS Database with the same name and tables as your VFP Database and then  use remote views to access this data. Each view in your ADS would have a name that corresponds to a table in your VFP database. For a detailed description of how you can use VFP in this manner, see our article ‘Test Driving the Advantage’.

When you use Remote Views with ODBC, you can even reuse your old Visual FoxPro database by simply pointing the ODBC connection to it.  Since VFP is such a great data store, what are the benefits you get by using Advantage as a data store instead? One clear benefit is that you will at least rid your application of the perennial problem of database and table corruption so prevalent with File-Server databases such as Visual FoxPro. Secondly you now have a client/server application that could potentially scale to any size. Third, you deliver the benefits of increased storage capacity and data security to your clients. Unlike VFP, you could apply Login information to your Advantage Database Server. Fourth, you put your data in a format that is easily accessible by other xBASE tools as well as non xBASE tools such as Visual Studio .Net/Visual Studio 2005/Visual Studio 2008.

VFP provides other means to enable you build VFP applications that run against Advantage Database server. For example, you could use Cursor Adapters or SQL Pass Through (SPT) technology. However, if you need to get existing applications running quickly with minimal code amendments, Remote Views is the way to go.

Application Convergence and Migration:

Since Microsoft’s announcement of no VFP 10, any VFP developer worth his salt will be concerned with how to stay in business. How the VFP language evolves or whether it even survives will remain to be seen, but every VFP developer must decide on a way forward for their own portfolio of VFP applications. Advantage Database Server is also helping us in this respect. We are able to keep using and deploying our existing VFP applications while getting at the Visual FoxPro Database through Advantage from Visual Web Developer 2008.

From Visual Web Developer 2008, you can get at your data by using the Advantage Ole db Provider for .Net which connects through the Advantage Data Dictionary file (.add). in this way, we are rewriting (migrating) our applications while ensuring that both the existing windows based VFP application and the new web based version done with Visual Web Developer 2008 use the same database (convergence). This approach allows us to remain in business by selling our existing Windows applications and even enhancing it in VFP while doing a new version in another language. The existing VFP Database will eventually be converted to an Advantage Database so that the existing VFP app will be carried forward as a Windows version of the system while the new version done on Visual Web Developer will be marketed as a web based version.

Conclusion:

As a VFP developer., Advantage Database Server helps you in many ways. Most especially, you will be able to stay in business by selling various versions of your existing VFP apps and even reaching for an upscale version. You will also get an opportunity to develop new versions without breaking compatibility with existing applications. Reach out for unlimited opportunities….gain the true database advantage for Visual FoxPro….

Managed Hosting Services – A Reliable Platform for Network Applications

Managed hosting services provide a solid and reliable platform for a broad array of network applications that include Java application servers, SQL replication, Web server load-balancing or managed VPN and more. With a strong web presence being the need of the hour for website owners, web hosting plays a crucial role in defining adequate online visibility. Securing the best hosting solution from the multitude of services that are available and selecting a reliable hosting service provider are of utmost importance.

Among them, managed hosting services are considered the best, especially for small businesses, webmasters and other IT users who handle one or more websites.

What Is Managed Hosting Service and Do You Need It?

According to Wikipedia, “A dedicated hosting service, dedicated server, or managed hosting service is a type of Internet hosting in which the client leases an entire server not shared with anyone.” With managed hosting, your website does not share a server with any other websites and is dedicated only to your website.

With managed hosting, the server administration work is handled by the server host, who functions as your offsite team, taking care of your hosting solutions – security, storage, performance and maintenance – rather than the company that owns the dedicated server. This allows the company to focus more on their core competence, i.e. running their business.

You need a dedicated hosting service solution if you are dealing with large amounts of confidential information and are on a shared hosting model or facing outages and slow loading speed. With managed hosting services you can optimize mission critical IT infrastructure, reduce IT costs, improve application performance, scalability and reliability and maintain tight control over resources, bandwidth and hardware.

Need for Managed Hosting Services

Expert Responsiveness – Deliver value by putting IT staff in control of applications and application infrastructure. You get the latest technology, upgrades and tools, SLAs backed by an expert team to monitor, manage, respond and support your needs today and tomorrow, in step with your evolving business needs.

Proactive Infrastructure Monitoring- Infrastructure monitoring is the key to effective management. The service provider enables you to monitor availability and performance of your IT systems so that you can proactively take actions to maintain high uptimes. With managed services there is 24/7/365 equipment monitoring and proactive security scans.

Data Center Security – Protect yourself from threats like data leakage, data theft (external and internal), website defacement, denial of service, end-user security, e-mail security and legal risks.

Disaster Recovery - Otherwise known as business continuity, you can restore the integrity of your hardware, software and data and resume system operations fast without any damage to your reputation.

Lower Total Cost of Ownership (TCO) – Deploy new servers with zero capital expenditures on hardware and software. By moving to a managed hosting model enterprises can save up to 40% of their IT spending. Major savings on the costs of infrastructure, facilities, training and re-hiring, personnel and administrative overhead. This allows more efficient prioritization of IT staff.

Management of Mail and Messaging - Whether you are looking for support on bulk mailing, for mailboxes with storage capacity for your end-users or even an email security service that will stop spam, managed hosting does it all.

Managing your IT infrastructure as your business grows means new challenges every day. Opt for managed hosting services solutions designed to optimize mission critical IT infrastructure performance and provide flexibility to meet current business needs and future demand.

AJAX Development Services: Taking Web Applications Development to a New Level

With the growth of online marketing on the rise, many companies have opened online business wings to further their business profits. Also, there many are e-commerce websites which are specifically into online business. As such, many software development companies offer web applications development services. And as the competition in the online market hots up, web applications developers are constantly looking at technological innovations to provide clients and subsequently end users with more effective, interactive, robust, and user-friendly web applications. And one of the results of this quest for technological innovations is AJAX. It is an acronym for Asynchronous JavaScript and XML. It is a new technology which helps programmers and developers to come up with interactive and responsive web applications. Today, more and more companies are looking at AJAX development service to better serve their clients.

Strictly speaking, AJAX is not a new technology though. It is rather a result of combining various technologies which have been pre-existing. It combines the benefits of server technologies such as XML, XHTML, XSLT, and CSS. AJAX also includes characteristics of JavaScript. These technologies have their own advantages and disadvantages. AJAX harnesses the advantages of all these technologies to produce applications which are robust and user-friendly. This is why so many clients turn to AJAX development services companies who provide them with web applications which are more responsive and provide for easier loading.

Without going into the technological details of AJAX, the working of this technology can be briefly explained. When a user opens the browser, the AJAX engine is loaded into the browser itself. This technology enables to refresh the part of the web page at any given time. As such, the user need not wait for long for the web page to load. The response to user’s inputs and queries is quick and he need not see at the hourglass symbol or a blank page, which is the case with non-AJAX web applications.

AJAX has no doubt taken web applications development to the next level. The number of Ajax development companies is also bound to increase with many endorsing this technology.
