Explanation:
Oracle ADF view objects are business components that collect data from the
datasource, shape that data for use by clients, and allow clients to change that data in the Oracle
ADF Business Components cache
Oracle ADF Business Components uses a sophisticated caching system to improve performance
and maintain consistent views of data.
Note: To maintain reliable data consistency, many operations lock an account at the beginning of
the transaction. With an account hierarchy, this means that many of the associated accounts are
also locked. While this provides reliable data consistency, it can cause a lot of serialization which
decreases the throughput of the system.
If, through the use of account hierarchies, this problem affects your system, you may choose to
lock specific balance groups instead of the whole account.
