     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)

    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
