Connection pooling is very good idea and application is very common. Writing a database connection pool is not as difficult as you might think. The general system does not have much to do with connection pooling, and using your own connection pool may not be a bad idea. Here's an example of Oracle, but it's also possible for Teradata and Greenplum. In addition, I have implemented a method for connection validity checking (checkconn) and Recovery Conne

Optimizing query processing and data warehousing
While the Data warehouse market is now dominated by vendors such as IBM, Oracle, and Teradata, open source databases are Greenplum (PostgreSQL based) and Infobright (in collaboration with M
to query, and the result set is generated by a query that accesses one or more tables. Multiple tables that are accessed in a single query are "Connected" by using the paradigm defined in the Table relational column. Normalization is a data structure model used by relational database, which can ensure the consistency and eliminate data redundancy.
Relational databases are facilitated with the help of a relational database management system (RDBMS). Most of the database systems we use today are
