Datasource
A datasource is a logical database interface for a database connection. It can be seen mainly in the context of distributed systems. This way, the complexity behind the logical database connection is hidden. We speak here of transparency. The physical design behind the datasource is not relevant. This can be a database cluster or several distributed databases. This does not matter to the user of the database connection. The system is thus similar to the DNS, in which IP addresses behind a logical name are hidden. Especially in Java, this technology is widespread. The JTA ensures the transaction security of logical database connections. Single-level Edit source text
