Abstract:

One of the main characteristics of database driven applications is the strong tight coupling between application and database. Thus, any required change in the database schema leads to change in database access layer. Problems elicit during design phase (specifically in database schema defining and representation), development phase, and maintenance. If the database is shared between different applications, applying changes will be more difficult. The available solutions proposed adding a middle layer that receives query and returns results in a unified form. This research focuses on the limitations of tightly coupled architecture. In addition, it hits the challenge of loose coupling between cloud computing applications and databases by encapsulating the database access code and queries in a separate layer (a broker service) to separate database access code form the application to achieve loose coupling between application and database
