Architecture is an important feature and the very first step in the development of an application. n-Tier the term is used for multiple tier or multiple layers. n-Tier Architecture splits the solution process into different projects based on the business requirements. The main advantage of using n-Tier is that the complexity associated with the business and the process is reduced and it is easy to work with. The elements of performance, scalability and future development issues need to be considered when deciding on the architecture of the application depending on the priorities required.




The n-Tier application has three tiers or layers, they are called the presentation tier, the business tier and the data tier. Each layer interacts with the layer directly below, and has specific function to perform. Presentation Layer is responsible for displaying user interface to either programmer or end user. Programmer uses this layer for designing purpose and to get the data back and forth. In ASP.NET it includes ASPX pages, user controls, server controls and sometimes security related classes and objects.

The Business layer works as a mediator to transfer the data from presentation layer. In the three tier architecture the data access layer is not made to interact with the presentation layer. The architecture in ASP.NET includes using SqlClient or OleDb objects to retrieve, update and delete data from SQL Server or Access databases and passing the data retrieved to the presentation layer in a DataReader or DataSet object, or a custom collection object. The Data layer gets the data from the business layer and sends it to the database or vice versa. This layer is further divided into two sub layers Business Logic Layer (BLL) and Data Access Layer (DAL). DAL is responsible for accessing data and forwarding it to BLL. In ASP.NET it uses SqlClient or OleDb to retrieve the data and send it to BLL in the form of a DataSet or DataReader. BLL (Business Logic Layer) is responsible for preparing or processing the data retrieved and sends it to the presentation layer.

The Data layer gets the data from the business layer and sends it to the database or gets the data from the database and sends it to the business layer. In ASP .NET it is an SQL Server or Access database. It can also be Oracle, mySQL or even XML.
In an ASP.NET n-tiered architecture web pages do not make direct calls to the database. A given layer only communicates with its neighboring layers. ASP.NET Web pages should reference custom objects defined in the business object layer. These objects provide database information in a class structure.
The partitioning of ASP.NET applications into front-end, middle tier and back-end layers, the n-Tier architecture supports a more uniform, building block approach to application designs. Hardware and software for presentation, application and database functions can be scaled separately, and included more easily into complex e-Business environments.

In short ASP.NET web development the next generation version of Microsoft's ASP, is a programming framework used to create enterprise-class web sites that will be totally based on n-tier Architecture to make Microsoft .net Software Development Services and Development easy.

In the modern age of internet, every business needs a reliable platform to represent its activities globally. The demand of Software Development, SEO and e-business solutions has increased multiple times during last couple of years. Ultimate yield depends upon the right approach for sourcing the services.
Dependency over the computers and websites is increasing day by day. Businesses in almost all the trades are trying to present themselves globally through most impressive websites. Because of increasing globalization, having most advanced e- commerce solutions has become a necessity. Because of technical orientation of business environment, demand of reliable service providers dealing in E business solutions, search engine optimization services, software development etc has increased tremendously within last couple of years. Business owners are on continuous hunt for the source that could offer affordable and dependable web solutions to face the competition.

Software Development is the need of ever organization and every organization has its own specification. So, it becomes must to offer customized software for the specific application. The software must be easy to navigate, quickly to access and free from disturbing effects. Business owners prefer the software that can be expanded to accommodate future requirements. Software development companies provide comprehensive training also to make the users friendly with the supplied software.

E business Solutions are required to make the transactions secured, fast and convenient. The development of perfect E business Solutions need the zero gap understanding of requirements besides regular communication between the client and developer. E business Solutions can be designed either in house or at the set up of client. Only having good E business Solution serves no purpose, it needs management also. Therefore, most companies offer comprehensive package for it that includes development, management and training.

SEO (Search Engine Optimization) is the primary need of every website, if the business owner wants to enhance the exposure. SEO involves numerous tricks. SEO providers prepare a comprehensive plan keeping in mind apparent characteristics of website, immediate business requirements and budget. The SEO practices are applied in steps and results are monitored periodically. Generally, organizations avoid doing it at their own and they outsource SEO service from professional company.

As the end results depend upon the performance of service provider so the selection becomes crucial. Company profile, qualification of professional, clientele, previous records and ongoing projects are the major selection parameters.

Providing or getting services for SEO, software development or E business solutions etc is a long time activity. Therefore, the companies that believe in serving short term goals never succeed. Zero gap communication, transparency and perfect mutual understanding are must to make the efforts result oriented for both.

Eclipse, which is an IDE, has been one of the most useful Java application development environments for Java developers. Latest version of eclipse 3.1 has come with new hopes and new feature inclusions. This article provides information on some of such new features for Java application development by Java developers.
From the first release of eclipse Java developers expecting more and more from this development environment which has made it so popular over the period of time.

Developers’ community along with companies do like this environment of Java application development as it provides many things under single umbrella. New release of Eclipse version is expected to increase the usability and development friendliness to Java developers. One of the major new features of latest version Eclipse 3.1 is the wide support for new language constructions in J2SE. Generics, Enums and auto boxing, all are there with single IDE. Latest version of Eclipse comes with new and enhanced refactoring, code assistance and quick fixes.

The Eclipse updated version also supports incremental Java compiler, written in Java and supporting the different Java language levels. Java Developers are benefited with own compiler of Eclipse and thus they can get fast code compilation, smoother debugging and refactoring with diagnostic things. This compiler is also used to compile external application like JSPs.

More integrated help structure of latest Eclipse version makes it more productive in providing the help to Java developers by tracing their current development activity and showing them the help they actually need. Also, some of the features like web-like navigation has been added to link to related preferences to go forward and backward.

To make it easier to find preferences, in Eclipse 3.1 the dialog of preference can be opened directly from many editors and also visible from the context menu.

The small to mid-sized business (SMB) market continues to hold appeal as a large growth opportunity for many high technology companies. As those organizations experience increased competition for large enterprise sales, they often see the SMB market as an opportunity to continue their growth, without the fierce competition that occurs in the enterprise space. This is an overly simplistic view that does not take into account the needs and characteristics of the SMB market.


Small and mid-sized businesses need many of the same technology capabilities of larger enterprises, but they need it at a level of affordability that makes sense for their business. In addition, they expect to receive appropriate levels of support to help them implement the solution in their enterprise. For the latter, organizations have realized that SMBs will not tolerate “crippled” or “feature limited’ editions of their product and are starting to configure solutions that are truly designed for SMB customers. The support needs are a bigger challenge, one that is much more difficult to try to overcome.

Technology providers have three primary distribution strategies available to them:

• Direct Sales

• E-Commerce

• Channel Sales

Each of these choices carries with it a similar strategy for support. The choice of approach is driven by the number of different factors including technology maturity, opportunity size (revenue), and target market. It is not easy to implement multiple distribution strategies at the same time for similar products; therefore, one approach typical dominates.

If a business has targeted enterprises, they probably sell and service through a direct model. They may partner with systems integrators for implementation assistance, but these integrators typically have the same profile. The challenge for the SMB market is that selling and supporting solutions for SMBs often requires a similar sales and service approach to selling direct, albeit on a slightly smaller scale (i.e. smaller teams, shorter decision reviews). As a result the cost structure of an organization that has sold to enterprises does not lend itself to selling to SMBs.


For the SMB, they get a level of attention that they need, without paying high fees for travel expenses and direct consulting resources. The solution provider gets a profitable relationship that they can benefit from through the years as they help their SMB customer leverage new technologies.

One of the hottest trends in the technology industry is software as a service (SaaS). The SaaS market is dominated by emerging vendors who are providing customers with a new cost model for software--on with no upfront licensing or special hardware needed; all that’s needed is an Internet browser and pay as you use via a monthly subscription arrangement. While this changes the core approach to purchasing software, it does not change the fundamental need for support and assistance in getting maximum value from these solutions for the business.

Most SaaS vendors use an e-commerce model to sell their solutions. Part of this is driven by the fact that the revenue model does not lend itself to direct sales and part of this is driven by the nature of the technology—since you access it with a browser, why not just purchase a subscription the same way. As vendors get established, they are typically expanding beyond e-commerce with a direct sales and service force. The interesting thing is that most of those vendors are pushing to get larger and larger deals and competing with traditional enterprise vendors.
As a result, the SMB customer, who has been an early adopter of SaaS due to the affordability, is left in the cold. They get second class support. One customer of a major SaaS provider talked about how they always spoke with someone new when requesting support. Each time it was like starting over, explaining their business, how they were using the software, and their problem. SMBs often feel like an unappreciated stepchild in these circumstances.

For the SaaS market to thrive, the SMB needs to be embraced as a key market for SaaS solutions. This requires that SaaS vendors use an alternative distribution strategy—leveraging channels. The local and regional solution providers benefit from this approach as they can continue to be involved as trusted advisors to their SMB customers, while gaining recurring revenue stream (something many solution providers desperately need) from their share of SaaS subscriptions.

The SMB customer benefits by getting local service and support from someone who truly cares about their business and has a cost structure that makes providing that support good for business. The SaaS vendor benefit in that they can gain, and keep, traction in the SMB market and not be forced to move upstream to enterprise deals because of cost challenges.

When SaaS vendors allow for channel partners to use their application for marketing by co-branding and white labeling the solution, the SMB feels that they are receiving a local solution that is supported because the name and logo of their partner is directly on the software. In fact, a call center application vendor named Visitar provides SaaS software only through the channel and priced exclusively for the SMB – Visitar’s hosted application is co-branded and white labeled by channel partners so as to give the SMB the most localized feel.

The SaaS market opportunity and the realities of cost structures for technology providers is yet another indicator that solution provider channels are here to stay. When the Internet and e-commerce first appeared, many pundits stated that the days of the solution provider channel were numbered. That was wrong. What is right is that solution providers must add value by serving as trusted advisors and affordable providers of local support and service to their SMB customers. When this occurs, everyone wins—the customer, the solution provider, and the vendor.

You have probably heard the phrase Software as a Service (SaaS), and you may have even tried out some basic SaaS applications, such as online word processors and spreadsheets, or free email accounts. You may be wondering if this new technology is useful from a business point-of-view and if SaaS is relevant to a small business owner or if it is strictly a big business enterprise service.


Software as a Service has been through a series of incarnations since its first appearance in the late ‘90s. Known then as application service providers (ASPs), the first companies to offer software via the web tried to emulate complex desktop applications by adapting desktop programs to a hosted model, resulting in large, complex software that would load or run very slowly via a web connection. SaaS requires more bandwidth than the dialup connections that most businesses were using at that time. As a result, most ASPs failed, and the ASP model became associated with some of the over-hyped claims of the dot-com days.

SaaS Revolution
Today, even the smallest businesses have a cable or DSL connection and satellites now offer fast wireless connectivity. SaaS designers have also written software that is specifically designed for Web delivery, resulting in an improved user experience. There are many advantages to using SaaS applications:

• Customers can access their data from any computer or mobile device with an Internet connection.
• Desktop clients aren’t necessary because accounts are accessed via the Web.
• Data is housed in secure data centers with expandable capacities.

Small businesses can take advantage of SaaS applications for collaboration or sales force automation. For example, an office administrator can easily schedule meetings for busy executives with shared calendars, and online file repositories enable employees to access and maintain up-to-date documents or contracts from any location.

The current crop of SaaS applications now function at higher speeds because of breakthrough technologies, such as Asynchronous JavaScript and XML (AJAX). These technologies enable automatic changes to content without requiring the full Web page to reload, allowing users to rapidly move between different areas of the application and assuring fast page loads. The result is software that operates much like familiar desktop software and provides similar functionality. For example, the improved interactivity and usability of the applications make it easy to conduct real-time actions, such as drag and drop, grab and scroll and grab and zoom.

Breaking Out of the Box
There is a significant difference between SaaS and traditional “boxed” software and how they are offered to customers, which can impact a customer’s bottom line. Software companies that sell boxed software must conduct regular upgrades to remain viable and to meet the latest system requirements. Customers are also usually locked into long-term contracts that require them to stay with a software provider and conduct a variety of upgrades over the life of the contract.

SaaS vendors, however, earn their revenue by charging a subscription fee, usually a monthly, per user charge. Keeping the customers happy keeps their revenue flowing. If customers are dissatisfied, they can quickly end their subscription. As a result, SaaS providers must constantly improve their products and provide these upgrades at little to no cost to the subscriber. With SaaS, costs are lower, more predictable and include support and service, giving smaller businesses access to applications that once required large investments in hardware, software and IT staff that only large businesses could afford.

Enjoy the Peace-of-Mind
The most common concerns about using SaaS for critical business functions, such as communication and finance, are security and reliability. Businesses cannot afford to lose access to their data, let alone lose the data altogether. The reality is – for small businesses in particular – company data is generally safer in a SaaS application than it is in an office. SaaS providers use extremely secure Tier I data centers to operate their applications and store customer data, and they have extensive back-up protocols that function 24 hours a day. SaaS customers can enjoy piece-of-mind knowing that their data is protected, readily available and accessible at any time.

SaaS proponents see a day – in the not too distant future – when businesses, regardless of size, are more mobile and less dependent on access to specific computers loaded with costly software. Many small businesses are freeing themselves from the limitations of boxed software, and it is this liberation that defines the SaaS revolution.

Today Java and .Net is widely used for web or desktop application. Each has its own feature and functionality. However, Java is most suitable then. Net. This article provides shows difference between java and .net.
Java is a creation of Sun Micro systems while .Net is a product from the stable of Microsoft. Both Java and .Net are used to build a comprehensive web services system and enterprise applications.

The Enterprise Edition of Java 2 Platform was created to ease the process of java application development, design and deployment of complex enterprise solutions and the J2EE architecture is based on Java. .Net is a product suite that allows an organization to create enterprise-class web services. The difference between both is that that .Net is a product strategy while J2EE is an industry standard that gives a developer the option to choose vendor products and tools. .NET is based on the language C# and while Java runs on any platform with the help of Java VM, C# can only work on Windows currently.

J2EE includes a number of features that help in boosting time-to-market and is not typically found in .NET. For instance, in many ways the developers do not need to concentrate on writing too much code due the state management services and therefore this accelerates the application development. This feature is not found in .NET, however, there are other features that .NET may possess but not Java. For example, ASP.Net does not require a client device and without rewriting the code, it can render user interfaces to alternate user interfaces.

The support for existing systems offered by J2EE and .Net is quite different and in some ways, J2EE is much more superior to the support offered by .Net. Most organizations will have code that can be written in a number of different languages and it is important to integrate them so that they can be reused in the future. J2EE Connector Architecture (JCA) helps in adding resource adapters that can communicate with existing systems. Though .Net also offers integration through the Host Integration Server 2000, however, it is not as superior or flexible as J2EE platform.
