Synchronizing data using BIRT Analytics Admin
The Synchronize option in BIRT Admin allows the administrator to update the application database to contain the most recent changes in the BIRT Analytics Engine repository. Execute this option after making a change in the analytical repository that alters the database structure, such as the addition, modification, or deletion of a column, table, or other data object. Synchronizing is also required when you change the data, after increasing, reducing, or modifying the records in a database.
After synchronizing the data you must set the privileges for the users or groups to provide access to the database. In the BIRT Analytics security options list, the ACL to objects option allows the administrator to create, modify, or delete a security group or access control list (ACL) and manage privileges over database objects.
