BW EDW LSA Grid
Consistent EDW Architecture – Consistent BI & Reporting
BW EDW Standard LSA Layers
Layer and naming qualifier
BW EDW LSA Data Domains ^(standard Partitioning)
Example:
C D B F E A
Standard Logical Partitions (Domains) and naming qualifier
Naming (e.g. DSO)
‒ Layer: byte 1
‒ Content Area: byte 2 to 5
‒ Sequence number: byte 6
‒ Domain: byte 7
‒ Sub-Partition: byte 8

BW EDW with LSA is the accepted approach (not just for large companies) guaranteeing
standardized BI & Reporting on all organizational levels (local, regional, global) on the same
consistent, common data foundation (single version of truth)
BW EDW with LSA stands for:
High availability - 24x7
operational robustness
organizational independency
scalability
maintainability e.a.
The LSA is the corporate framework
for BW to manage reliably
the entire data & meta data life cycle:
Data delivery (extraction, RDA)
Data modeling (assign InfoObjects)
Data staging
Authorizations
Solution delivery (transports)
BW Layered Scalable Architetcure - Value & Positioning
consistent, high Availability EDW for standardized BI

Perception of BW EDW with LSA on RDBMS
Shortcomings
An BW EDW with LSA is perceived as highly valuable but
costly: building it, moving steadily data to and within the EDW
not flexible enough: EDW/LSA standards, central development, overall responsiveness to business
needs (operational & agile BI)
Number of persistent InfoProvider
overall missing flexibility, agility
No direct business value of Acquisition Layer
EDW model (InfoObjects) assignment
Staging of data
Low Adoption of Near Real Time reporting
Costs of Corporate Memory
Setting up BW EDW - time to ROI
The BW data model (InfoObjects) must
be defined
The customer LSA must be defined
