The Database Application Development is often referred to as DAD or Datalog or as a generic term for applications that implement the principles of data warehouse technology. It is used in conjunction with the design of application software applications.
These application software applications are used by the users to conduct the necessary tasks related to information management. The database application design usually involves a series of steps that involve creating a data model, defining the functionality requirements, implementing the data model, coding and testing the application, and finally releasing the application for general distribution.
The Database design and development can be divided into several different phases: planning; implementation; designing of the database application; and testing the application. Each of these stages involves different steps and it is important to understand them fully so as to ensure the success of the entire project.
The first step is that the Database application design should be planned so as to enable the establishment of the basic functionalities required by the user or the client of the product. This would include designing a query language that enables the database administrators to define queries and also the database design itself. The SQL language is widely used by most businesses for establishing the basic functionalities.
The second stage involves implementing the database application development. A database application can be developed using the object-oriented programming (OOP) technologies such as C++, Visual Basic and Java and also the development environment such as the Visual Studio or the Eclipse platform. The database application can also be developed using the database back-end technologies such as C++.
The third step in the Database application development involves designing the application. The database developers usually have the responsibility to make the database functional for the users. The functionalities of the database that are designed can include the application security, database scalability, query processing and data integrity.
The fourth step in the database application development involves testing the database application developers. The database application developers perform various tests for database maintenance, data integrity, availability and scalability. These tests ensure that the database remains efficient and error free. The database engineers also perform all the maintenance tasks necessary to maintain the database such as back-porting changes from other databases or applications.
The fifth step in the database application development involves deploying the application for use by the users. This is done by the application server that is deployed by the developer on the servers. The applications usually need to be deployed manually on the server so as to provide the database developers with a control over the database installation process. Once the application is deployed, the database developers usually deploy it for use.
The sixth step in the Database application development involves managing the database to maintain the database security and performance. The database security and performance need to be checked periodically to ensure that the system can keep up with the changing demands of the business processes.
The seventh step involves configuring the application server for the database servers. The database servers must be configured to provide proper access to the applications to access the database.
The eighth step involves releasing the application server for general distribution. This is usually done after the database servers have been set up. In the final step of the DBMS development, the system must be released for general distribution and is usually done by the end users.
