Abstract: As we consider any database, then to retrieve the information in the files is an important issue. Mostly the files are arranged in proper manner by using the trees and No SQL database. This approach of TBAS (Tree Based Association Rules) plays an important role for reducing the retrieval time of query. So that, if the user wants to retrieve the information about any particular subject then it can be provided by the relational database in very less time because the information is stored in XML files i.e. the information is stored by using tags. In this way the retrieval time is reduces. This Intentional Knowledge of mined information is beneficial, and this is an unique way to manipulate both the structure and the content of the XML document and, exact answers to the user queries whenever it required.
