As the data is growing over the distributed environment day by day, a better distributed management system is required to manage this large data. Query optimization is a process of finding out better query execution plan from multiple available options. As there a multiple sites in distributed database having parts of the data, query optimization is one of the challenging tasks in distributed database. In this review paper query optimization challenges in distributed database and its basic steps have been studied. And a review of some proposed systems has been done.

Deaf and hard-of-hearing people do not have that luxury. This system will help those people by providing a medium to communicate. It is implemented using devices like flex sensors, and microcontroller.

Query optimization is a process of finding out better query execution plan from multiple available options. As there a multiple sites in distributed database having parts of the data, and the size of data is not static, a dynamic solution is needed to optimize queries in distributed database. The combination of Ant Colony Algorithm and Genetic Algorithm can be used to provide a dynamic approach.
