What is LSA architecture?

LSA is built with several layers, and data is physically copied from one layer to another. When we implement BW on HANA, we can create a different flavour of Layered Scalable Architecture, much simpler, smaller, faster and that relies more on virtual objects and less on copy of data between layers – It is called LSA++.

What is LSA and LSA ++ architecture?

When we implement BW on HANA, we can create a different flavour of Layered Scalable Architecture, much simpler, smaller, faster and that relies more on virtual objects and less on copy of data between layers – It is called LSA++. In LSA++ we have less number of layers (majorly 3 layers) compared to LSA as below.

What are the optional layers of LSA ++ architecture?

Create Custom PDF

• LSA++ Open Operational DataStore Layer – the Entry Layer.
• Open ODS View – Slimmed Down and Extended Acquistion-Services.
• Open ODS Layer – Immediate Query and Early Integration.
• The Harmonization Layer and Propagation Layer.
• EDW Data Propagation Layer in the LSA++
• Corporate Memory.

What is difference between LSA ++ and LSA ++?

The biggest difference between SAP’s earlier LSA and the above HANA LSA++ is the fact that queries can be directly built in BW on HANA on the DSO level and the additional layer of an Info cube /Multi provider is not needed.

What is the difference between SAP BW and SAP HANA?

Comparing BW on HANA and BW/4HANA SAP BW on HANA and SAP BW/4HANA are different application suites running on the same database. BW on HANA uses SAP’s legacy BW software, but moves it to the HANA database, while BW/4HANA uses a re-engineered software suite designed to fully harness the power of the HANA database.

What is the full form of LSA?

LSA Full Form

What is LSA BW?

The Layered Scalable Architecture (LSA) is SAP’s Best Practice and Reference Architecture for building an Enterprise Data Warehouse with SAP NetWeaver BW.

What all are the elements of LSA?

The resulting patterns are used to detect latent components.

• Occurrence matrix.
• Rank lowering.
• Derivation.
• Commercial applications.
• Applications in human memory.
• Semantic hashing.
• Latent semantic indexing.
• Term-document matrix.

What is the difference between BW on HANA and bw4hana?

SAP BW on HANA and SAP BW/4HANA are different application suites running on the same database. BW on HANA uses SAP’s legacy BW software, but moves it to the HANA database, while BW/4HANA uses a re-engineered software suite designed to fully harness the power of the HANA database.

What all are the elements of LSA ++?

LSA ++ is a flexible consistent Data Framework virtually wrapped that consists of 5 main parts:

• EDW Propagation Layer.
• The Architected Data Mart Layer.
• Open Operational Data Store Layer.
• Agile Data Marts and BW workspaces.
• BW Virtual Data Mart Layer.

Is SAP HANA and ERP?

A fast and powerful database that provides real-time, multi-model data analytics, SAP HANA serves as a platform for enterprise resource planning (ERP) software and other business applications.

What is BW on HANA?

SAP Business Warehouse (BW) powered by HANA also known as BW on HANA (BWoH) is SAP’s data modeling, warehousing, and reporting tool built on the HANA database. SAP BW on HANA (BWoH) runs on the HANA database and therefore it is simpler and faster.

Which is the reference architecture for SAP LSA + +?

The in-memory capabilities of HANA enable BW to expand it’s focus to a more open logical architecture with less persistence and even more flexibility and scalability. The LSA++ is the reference architecture for implementing an EDW with BW powered by HANA.

What does the LSA mean for SAP BW?

In short the LSA is all about standardization of your future BW. The emphasis is on: where and how to standardize your architecture. The LSA calls these architecture topics ‘Building Blocks’.

What is the BW layered scalable architecture ( LSA )?

The BW Layered, Scalable Architecture (BW LSA) describes the design-principles of service-level oriented, scalable, best practice BW architectures founded on accepted EDW principles. As with all high-level definitions that sounds little concrete. Let’s have a closer look at LSA principles. LSA at a glance

Which is the reference architecture for SAP Edw?

The Layered Scalable Architecture (LSA) is SAP’s reference architecture and best practices how to build an EDW with BW. The LSA was established several years ago already and is based on industry best practices, e.g. the Corporate Information Factory (CIF) from Bill Inmon.
