As the Internet has become a major player on the global economic front, so that the number of investors who are interested in its development. So, you may be wondering, how the Internet will continue to play a major role in the field of communications, media and news? Keywords are: Web Application Projects.Web applications are business strategies and policies implemented on the Web through the use of the user, business and data services. These tools are where the future lies. In this article I would like to major stages in the life cycle of a Web application of the project, explain your options, and help you formulate a plan of Web application for the success of your own efforts. First, though, we will take a brief overview of Web applications.Who needs of Web applications and why? There are many entities that require applications for the Web and an example would be business-to-business interaction. Many companies in the world today seeks to do business with them in a safe and private networks. This process is increasingly popular with a lot of foreign companies that outsource projects to each other. From the simple process of transferring funds to a bank account, large-scale deployment of Web services that provide updates on the network pricing information at the global level, the adoption of an infrastructure for Web applications is essential for many companies Web Application ModelThe Web application model, like many software development models, is built on 3 levels of user services, business services and data services. This model breaks the application into a network of consumers and service providers. The user creates a service level visual gateway for consumers to interact with the application. This can range from basic HTML and DHTML complex COM components and Java applets. Users then enter the business logic and procedures of the Business Services. This level may vary script Web ASP / PHP / JSP to the server-side programming, such as TCL, CORBA and PERL, which allows the user to perform complex actions through a web interface. The last level is the Data Service layer. Data services store, retrieve and update information at a high level. Databases, file systems and write the media are all examples of data storage devices and recovery. For Web applications, however, databases are the most practical. The databases allow developers to store, retrieve, add, update and categorical information in a systematic and organized. ProjectChoosing Choosing the right types of projects to work on is an extremely important part of the plan for developing Web applications. Assess your resources, technical expertise, and publishing capabilities should be your first goal. Taking the 3 floors into account, prepare a list of all available resources that can be unequivocally attributed to each level. The next would 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 healthy dose of success? These are questions that should be answered before you sign any tenders or contracts. Let's look at an example. A company called ABC needs to develop a web application that will display data on the sales made by the different sales agents. The data is updated daily through a fully automated process from each of the 3 levels of service. The client tells you that the entire project should be done by ASP / SQL Server and you need to host the application as well. After evaluating all your resources, you and your team to reach a conclusion that the company is unable to make backups of the data on a daily basis. After further discussion, you realize that this is a very important part of the configuration of your client, and you should not risk taking a chance with the project. It is very likely that you will be better prepared next time, when a similar project lands on your desk, if you refuse employment and to recommend someone else who has the means to do well in a now.The Phases Web Application ProjectThe Web application development process has 4 phases: Consider the nature and direction of the projectDevising the planDevelopmentTesting, support and stability Let's look at each of these in more detail.1. Consider the nature and direction of the projectIn this phase, management and developers assigned to the project to meet and establish objectives that the solution must be achieved. This includes recognizing the limitations that are placed on the project, planning and versions of the application. At the end of this phase, it should be clear that the documentation on the implementation achieve.2. Designing the planIn this phase, you and your team must determine the "how" of the application. What scripting language is the most appropriate, which must include the characteristics, and how long will it take? These are some questions that must be answered through the planning phase. The main tangents are at this point the project plan and functional specifications. The draft plan sets out a calendar of events and tasks, while the functional specification describes in detail how the application will work and flow.3. DevelopmentOnce the project plan and functional specifications are ready, the benchmark is set for development work to begin. The programmer / s or Web developer / s start coding, testing and publication of data. This phase sets the variable data entities and encryption procedures to be used later in the draft. A landmark document is prepared by the development team, which is then forwarded to the management for review.4. Testing, support and stability stabilityThe phase of the project focuses mainly on testing and eliminating bugs, anomalies and network issues that could cause the application to fail. It is here that the policies and procedures are established to support the success of system.Web Application Development - A Guide to Your Options SuccessKnowing and WiselyOk Thanks to them, now that you have an understanding of architecture and procedures behind the Web application development, let's get that technical options you need to consider for the development process itself. Windows Web ServersMicrosoft has built a loyal clientele an important factor - their easy-to-use software. Windows NT/2000/XP Web servers are very fast and easy to administer. The fact that the Windows operating system is a shell which means that the directors and writers can easily enable the Web server to interact with other applications software and hardware to transmit and receive data via the Internet. Popular scripting server side used with Windows servers are ASP / ASP. Net, Java Server Pages and PHP. UNIX / Linux Web ServersUNIX 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 websites large who need content management systems or receiving a very high volume of traffic. Popular scripting in UNIX server side are Java Server Pages, PERL, PHP, the scripting language and CORBAEvery has its advantages and disadvantages. As I have not written a book here, I will use the ASP model as my language of illustration. When working with Windows servers, there are several important parameters that the application developer needs to throw into the equation, including security, scalability, speed and application design. So below I will help you to formulate a plan for success to accomplish all sorts of projects.Planning Web for a successful Web development ProjectIn drastically to minimize the risk of project failure, I have always approached my application development projects in the following areas Sequence.1. Identify entitiesStart business logic and by collecting information on everything you have. If you are going to work with databases, start by enumerating the number of entities will be used in the business logic. For example, if your program implements sales data, the sale of tickets is an entity. Once you have identified all entities to establish a clear rule about their relationship. This can be done through presentations, charts or even reports.2. Create a draft functional specification and planThis party, in my opinion, is the most important part of the project. Functional (technical or functional characteristics) is a map, or blueprint for how you want a web application to look and work. The specification details that the finished product be done, interaction with the user, and its look and feel. One advantage of writing a functional specification is that it streamlines the development process. It takes discrepancies and speculate on the programming process, because the level of detail that goes into the plan, it is possible to minimize the misunderstanding which is usually tied to unanticipated projects. See examples of functional specifications RayComm.com.Once well written to the functional specification is complete, a project plan must be devised. A project plan is a timetable of tasks and events that will take place during the project. The project manager or program is normally the person who creates a project plan, and their main objective is to give details of the task notes while also being able to host and resource planning information. You can download a sample Excel file for a project plan to Method123.com.3. Bring the application model in playAs discussed above, the application model consists of 3 levels - user, the company and levels of data services, each of which serves a purpose. Practically speaking, it is always better to start with the data level, because you have already identified your entities and understand their relationships. The level data can be an SQL server database, a text file, or even the powerful and robust Oracle. Creating tables, relationships, jobs, and procedures depending on what platform you choose. If the data warehouse (ie data that already exists and does not depend on real-time interaction), then make sure that new data can be added in a secure and scalable fashion.A Quick tip: views using SQL Server / Oracle can dramatically improve productivity and performance of your application. They increase the rate because they are "stored issues" which have no physical existence. The level of business services, in my opinion, is the heart of the application. It involves the implementation of business logic in language scripting or programming. At this stage, make sure that you have already set up your environment for testing and debugging. Always test on at least 2 cases in your application, after all, what can work perfectly for you, can do so on many other platforms or machines. ASP, XML, PHP, JSP and CGI are examples scripting server side used to the business service level. What language of your choice, make sure it is capable of managing all activities outlined in the functional logic specification.The final level is the user, which is absolutely vital for the interactive and strategic elements in the application . It provides the user with a visual gateway to the service activity by placing images, icons, graphics and layout elements in strategic areas of interest, in most cases, based on research on the management. If you develop the user to level yourself, make sure you have studied your competitors. The last thing you need is for your application to look exactly the same as someone else .4. Develop a support schemeBeing able to sustain and stabilize your application is very important. Establish an appeal process for cases of failure, avatars, or even downtime. Give your customers the opportunity to contact you in case of an emergency relating to the programme. A good example of a programme of support is a system for monitoring ticket. This system allows users to submit files to a request for assistance and the support team, the case could then follow. This means that the application is identified by a unique code or number. Although tracking systems tickets are normally used by hosting companies or scale of the ASP (Application Service Providers), they continue to serve a valuable purpose by helping to keep the application stable.Over You ... So that - a framework from which you can start to plan and develop your own Web applications successfully. Web Applications will be around for a long time to come. As we move further into the future, they will become less manual and more automated. This will lead to new types of research, but for the moment, we can be satisfied that this is what drives the Web.
