Depending on your usage, you can leverage SQLite’s flexibility to work on multiple Databases in the same session simultaneously. SQLite is used as a Temporary Dataset for Applications to get some processed data. SQLite is a cross-platform DBMS, hence you can access it over all platforms includ...
1. Logical Extraction involves extracting data from a database or other structured data source in a way that preserves the relationships and integrity of the data. Logical extraction typically uses a database management system’s (DBMS) query language or API to extract the data in a structured...
Adding the right driver implementation to our Java runtime environment, properly setting up the DBMS and changing the database access configuration is all we need to do. Below, in step 3, we explain how to set up the JPA configuration for MySQL. 1. Step 1 - Set up the Folder Structure...
We also outline a possible extension of existing processing strategy for relational DBMSs to the new and extended requirement of KBMSs and propose possible solutions for improving the evaluation efficiency of user submitted requests. Finally, we discuss the two alternative evaluation strategies for ...
