Abstract: Nowadays distributing data among different locations is very popular due to needs of business environment. In today's business environment, accessible, reliable, and scalable data is a critical need and distributed database system provides those advantages. It is a need to transfer data between sites while processing query in distributed database system, if the connection speed between sites is low then transmitting data is very time consuming. Optimizing distributed query processing is different from optimizing query processing in local database system. Most of the algorithms generated for distributed query processing focus on reducing the amount of data transferred between sites. Join operation in database system is for combining different tables with a common join attribute value, if the tables that are put in a join operation are at different locations then some of the tables are needed to be transferred to between sites. Join operation optimization algorithms in distributed database system focus on reducing the amount of data transfer by eliminating redundant tuples from relation before transmitting it to the other site. This thesis introduces a new distributed query processing technique named distinct encoded records join operation (DERjoin) which considers duplicated join attributes in a relation and eliminates them before sending the relation to another site.
