Centralized relational database connections
Relational database connections are now configured separately from the database tables or views. This means that if there are several tables in the same relational database, only a single connection to that relational database is needed. This has many advantages. The biggest is that it minimizes the effort needed if a change occurs in the database connection.
For example, if the password needed to access a relational database server changes on a regular basis, the project needs updated. With relational database connections, it is only necessary to update the connection, and not each individual database table. This minimizes the time it takes to maintain your project as well as the complexity level in keeping your project up-to-date.
