RE: What is a Universe?
|
| A universe is a semantic layer or in more familiar terms a data abstraction layer which is built with the Business Objects Designer tool. This semantic layer is where you define your "Business Objects" which are essentially encapsulated snippets of SQL that when properly built express a leggo-like bit of business logic that can in the reporting tool or through an application be used and reused to build reports. The genuis of this is that this data abstration layer sits between the database and your reports or application. This means that even if the database structure changes, that instead of being required to change what could be hundreds or even thousands of reports throughout an organization to accomodate the change, you instead make the changes in the universe and those changes are automatically passed through to all the reports. This has numerous benefits one being that it allows a much more flexible environment for preparing for and facilitating change in an organization. |
