Migrating universes to SAP Business Objects 4.0

In order to migrate  a universe from a prior CMS release (XI R3.1 and XI r2)  to a BI 4 CMS,
you must use the Upgrade management tool  (UMT) that is provided with BI 4.


SAP Business Objects 4.0 BI 4 includes two universe development tools:
- The universe design tool, which is an upgraded release of the Universe Designer tool you are familiar with if you are an existing Business Objects customer wich creates a UNV file.
- and the new Information design tool (IDT), which is the new universe authoring tool provided with BI 4 that produces a UNX file.

A UNX universe file is published on the CMS  is the result of a merge of three components that are designed in the information design tool.:

-  CNX files for connections
-  DFX files for data foundations
-  BLX files for business layers

 A UNX is the result of CNX + DFX + BLX

 where:
the data foundation   (DFX ) 
contains a schema  of tables and joins from one or more relational databases ,  through connections (CNX), that are used as a basis for one or more business layers.

 the business layer (BLX)
 is a collection of metadata objects that map to SQL or MDX definitions in a database, such as columns, views, database functions, or pre-aggregated calculations. 
These objects include dimensions, hierarchies, measures, attributes, and predefined conditions. 
Each object corresponds to a single  business information that can be used in a query in order to collect data.

This increase in capacity and reduction in cost makes it a  viable approach to keep huge amounts of business data in memory. This section discusses  the benefits and challenges. In few words you can understand SAP HANA plus  analyzing this evaluation: Typical access speeds Disk     4,000,000 ns Memory         0.4 ns Speed   10,000,000 Falling prices move processing from Disk/SSD to In-Memory In-Memory Computing The elements of In-Memory computing are not new.
