Description:
The JdbcDatabaseInfo class tries to load all the
database metadata information when it is instantiated.
We found this inconvenient since in our Oracle database
we already have thousands of tables and retrieving the
whole metadata is time-consuming and inefficient in
case of simple updates (one or two tables).
We made some modifications in the JdbcDatabaseInfo
class so that the metadata information for each table be
loaded only when needed. Once the metadata for a table
loaded, it is kept in memory for later use.
