The global economy has the internet as a major player now. Businesses are choosing customized website applications that are designed to facilitate the smooth running and functioning of their work. The website application development process is best handled by companies offering such services, and owners and operators of various kinds of businesses are taking full advantage of hiring these companies.
If you are thinking of hiring web developers, then some basic information is given below, about the tools they use and their purposes. The common website applications are developed by using-
These applications allow enterprises to connect and work better with their employees, customers and businesses associated through web services. Each and every tool can fashion specific applications, for instance, .Net technology is ideal for building, managing and using secured connected solutions with web applications. Whereas, for creating dynamic and interactive applications in Linux platform, PHP is used. If you have an e-commerce website, then your web applications developers may use PHP for building e-commerce sites with shopping carts and CMS, CRM, and other essential features.
Expert website application developers use JavaBeans technology for developing JSP based website applications, whereas ASP applications are developed by ActiveX components. For customized business solutions to companies, developers use Java. Features like ERP, CRM integrated search, data warehousing, administration panels, CMS, RSS Feeds can be assured with a Java web solution. Java software development provides software solutions for sales force automation and any other specific business related solution. Website application developers have the technical expertise to automate many manual functions for web development, including-database design, forms design and other capabilities (that would be otherwise coded manually).
Other tools are also designed to create customized web applications that will help companies perform better. You must remember that a good application Development Company will stand apart from others by choosing the better tools, platforms and languages to implement in developing web applications. You must get the promise of high efficiency and user friendliness from the web developers when they offer to create customized web application. For smooth functioning of your enterprise, as well as for you to meet your goals and improve the means and methods of your business, you must hire a trusted, reputable and highly skilled web application development company.
* The company must have a highly professional and dedicated work force.
* The company must maintain quality standards.
* They must have excellent customer relationships.
* They must be armed with the knowledge and experience of developing all types of web applications (and that too by utilizing different platforms and tools).
All the above mentioned pre-requisites will ensure that you get better result to the end-user. User interface is an important aspect that a good web application development company adheres to. The web application and business reporting software must be offering complex solutions but should not be so complicated that the user cannot understand or use it.
From the good old days of the tag, to the XML-savvy Web services of today, applied Internet language has come a long way. And nowhere is this more evident than in the field of Web application development.
As the Internet grew into a major player on the global economic front, so did the number of investors who were interested in its development. So, you may wonder, how does the Internet continue to play a major role in communications, media and news? The key words are: Web Application Projects.
Web applications are business strategies and policies implemented on the Web through the use of User, Business and Data services. These tools are where the future lies. In this article, I’ll take you through the essential phases in the life cycle of a Web application project, explain what options you have, and help you formulate a plan for successful Web application endeavors of your own. First, though, let’s take a brief overview of Web applications.
There are many entities that require applications for the Web-one example would be Business-to-Business interaction. Many companies in the world today demand to do business with each other over secure and private networks. This process is becoming increasingly popular with a lot of overseas companies who outsource projects to each other. From the simple process of transferring funds into a bank account, to deploying a large scale Web services network that updates pricing information globally, the adoption of a Web applications infrastructure is vital for many businesses.
The Web application model, like many software development models, is constructed upon 3 tiers: User Services, Business Services and Data Services. This model breaks an application into a network of consumers and suppliers of services.
The User Service tier creates a visual gateway for the consumer to interact with the application. This can range from basic HTML and DHTML to complex COM components and Java applets.
The user services then grab business logic and procedures from the Business Services. This tier can range from Web scripting in ASP/PHP/JSP to server side programming such as TCL, CORBA and PERL, that allows the user to perform complex actions through a Web interface.
The final tier is the Data Service layer. Data services store, retrieve and update information at a high level. Databases, file systems, and writeable media are all examples of Data storage and retrieval devices. For Web applications, however, databases are most practical. Databases allow developers to store, retrieve, add to, and update categorical information in a systematic and organized fashion.
Choosing the right types of projects to work on is an extremely important part of the Web application development plan.
Assessing your resources, technical skills, and publishing capabilities should be your first goal. Taking the 3 tiers into consideration, devise a list of all available resources that can be categorically assigned to each tier.
The next consideration should be the cost. Do you have a budget with which to complete this project? How much will it cost you to design, develop and deliver a complete project with a fair amount of success? These are questions that should be answered before you sign any deals or contracts.
Let’s look at an example. A company called ABC needs to develop a Web application that will display sales information created by different sales agents. The data is updated daily through a completely automated process from all 3 service tiers. The client tells you that this entire project must be done in ASP/SQL server and that you should host the application as well.
After assessing all your resources, you and your team come to a conclusion that the company is unable to do data backups on a daily basis. After further discussion, you realize that this is a very important part of the setup for your client, and you should not risk taking a chance with the project. It’s very likely that you will be more prepared next time around, when a similar project lands on your desk, so you decline the job and recommend someone else who has the capabilities to do it right now.
The Phases in a Web Application Project:
Let’s look at each of these in more detail.
In this phase, the management and developers assigned to the project come together and establish the goals that the solution must achieve. This includes recognizing the limitations that are placed on the project, scheduling, and versioning of the application. By the end of this phase, there should be clear documentation on what the application will achieve.
In this phase, you and your team must determine the how’s of the application.
What scripting language is most appropriate, which features must be included, and how long will it take? These are some of the questions that must be answered through this planning phase. The main tangents at this point are the project plan and functional specification. The project plan determines a timeframe of events and tasks, while the functional specification outlines in detail how the application will function and flow.
Once the project plan and functional specification are ready, a baseline is set for the development work to begin. The programmer/s or Web developer/s begin coding, testing and publishing data. This phase establishes the data variables, entities and coding procedures that will be used throughout the remainder of the project. A milestone document is prepared by the development team, which is then handed to management for review.
The stability phase of the application project mainly focuses on testing and the removal of bugs, discrepancies and network issues that may otherwise cause the application to fail. It is here that policies and procedures are established for a successful support system. Knowing Your Options and Using Them Wisely Ok, now that you have an understanding of the architecture and procedures behind Web application development, let’s look at what technical options you’ll need to consider for the development process itself.
Microsoft has built a loyal customer base on one important factor – their easy-to-use software. Windows NT/2000/XP Web servers are very fast and easy to administer. The fact that the operating system is a Windows shell means that administrators and authors can easily allow the Web server to interact with other software and hardware applications to transmit and receive data over the Internet. Popular server side scripting languages used with Windows servers are ASP/ASP. net, Java Server Pages, and PHP.
UNIX has long been known for its reliability. It is a powerful and robust Web server and operating system. Unix is the server of choice for many large-scale Websites that need content management systems or receive an extremely high volume of traffic. Popular server side scripting languages for UNIX are Java Server Pages, PERL, PHP, and CORBA.
Every scripting language has its pros and cons. As I’m not writing a book here, I’ll use the ASP model as my language of illustration. When working with Windows servers, there are several important parameters that the developer needs to throw into the equation, including security, scalability, speed and application design. So below I’m going to help you formulate a successful plan to accomplish all kinds of Web projects.
In order to drastically minimize the risk of project failure, I’ve always approached my application development projects in the following sequence.
Start by gathering information on everything you have. If you are going to be working with databases, begin by enumerating how many entities will be used in the business logic. For example, if your program implements sales data, a sales ticket would be an entity.
Once you’ve identified all your entities, establish a clear guideline for their relationships. This can be done via presentations, flowcharts or even reports.
This part, in my opinion, is the most important part of the project. Functional specifications (or functional specs) are a map, or blueprint for how you want a particular Web application to look and work. The spec details what the finished product will do, user interaction, and its look and feel.
An advantage of writing a functional spec is that it streamlines the development process. It takes discrepancies and guesswork out of the programming process, because the level of detail that goes into the plan makes it possible to minimize the misunderstanding that’s usually associated with project mishaps. A project plan is a timeline of tasks and events that will take place during the project. The project or program manager is normally the person who creates a project plan, and their primary focus is to detail task notes while being able to accommodate scheduling and resource information.
As discussed earlier, the application model consists of 3 tiers – The User, Business and Data service tiers, each of which serves a substantial purpose. Practically speaking, it’s always best to start with the data tier, because you’ve already identified your entities and understand their relationships. The data tier can be an SQL server database, a text file, or even the powerful and robust Oracle. Create tables, relationships, jobs, and procedures depending on what platform you have chosen. If the data is a warehouse (i.e. the data already exists and does not depend on real time interaction), then make sure that new and additional data can be added securely and in a scalable fashion.
A quick tip: using views in SQL server/Oracle can improve dramatically the productivity and performance of your application. They increase speed because they are stored queries that don’t have a physical existence.
The Business services tier, in my opinion, is the heart of the application. It involves the implementation of business logic into the scripting or programming language.
At this stage, make sure you’ve already set up your environment for testing and debugging. Always test on at least 2 instances in your application, after all, what may work perfectly for you, may not do so well on other platforms or machines. ASP, XML, PHP, JSP and CGI are some examples of server side scripting languages used at the business service level. Whichever language you choose, make sure that it’s capable of handling all the business logic presented in the functional specification.
The last is the user tier, which is absolutely vital for the interactive and strategic elements in the application. It provides the user with a visual gateway to the business service by placing images, icons, graphics and layout elements in strategic areas of interest, most commonly, based on management research. If you’ll be developing the user tier yourself, be sure to have studied your competition. The last thing you need is for your application to look exactly the same as someone else’s.
Being able to support and stabilize your application is very important. Define a procedure call for cases of failure, mishaps or even downtime. Give your customers the ability to contact you in the case of an emergency relating to the program.
A good example of a support scheme is a ticket tracking system. This system allows users to file cases pertaining to a support request and the support team, then makes the case track able. This means that the request is identifiable by a unique code or number. Although ticket-tracking systems are normally used by hosting companies or large scale ASP’s (Application Service Providers), they still serve a valuable purpose in helping keep the application stable.
So there you have it – a framework from which you can begin to plan and develop your own successful Web applications.
