Multiple Database Support
 One Application inOpen-jACOB can access multiple and different kind of databases at the same time and in the same UI without any line of code. The data source could be a persistent store like an RDBMS, an external service like a B2B exchange or a repository like an LDAP database. The business component that relies on the Open-jACOB data access layer uses the simpler interface exposed by the data layer for its clients. The data layer completely hides the data source implementation details from its clients. Because the interface exposed by the data layer to clients does not change when the underlying data source implementation changes, this pattern allows to adapt to different storage schemes without affecting its clients or business components.
Database Reconfigure
 The deployment of a new application version sometimes requires the reconfiguration of the data sources assigned to the application. This is the case if the structure of the data sources is not in line with the structure expected by the application. You can reconfigre the database in the administration application of Open-jACOB neither with any line of SQL nor the user must logout to the current session. This is hot.
Query by Example (QBE)
 Query by Example (QBE) is a powerful search method that allows anyone to search a system for document(s) by entering an element such as a text string, document name, dates, date ranges,... quickly searching through the DB to match your entered criteria.
