Database Technology - Then and Now
Yesterday Today
Database systems were designed to perform well on systems with limited RAM
Modern servers can have 2TB of system memory, allowing complete databases to be held in RAM
Since slow disk I/O was the main bottleneck in data throughput, architecture was designed to focus on optimizing disk access
Multi-core server architecture allows CPUs to process increased data per time interval

Conclusion: Its now quickly becoming cost effective to move away from disk-based data storage to in-memory solutions

SAPs In-Memory Solution SAP HANA
SAP HANA takes advantage of modern advances in Multicore CPUs and inexpensive RAM.
SAP HANAs technology is based on storing data in-memory.
For Analytics, tables are typically based on a Column format (optimized for reads).
SAP HANA is a database technology it does not do anything without other Extraction, Transformation, Loading, and Reporting tools integrated with it.
SAP HANA consists of new modeling tools or can be integrated with other existing and understood SAP BW or ETL assets.
Insight. Innovation. Results.
Why? - SAP HANA is the Technological Future
New SAP BusinessObjects technologies require SAP HANA (i.e. SAP Predictive Analysis, SAP Lumira) to achieve full capabilities. Additionally, SAP HANA as a database appears to generally be the direction that SAP is taking for its products.
BW Accelerator only increases speed for reporting requiring special report design considerations. A SAP HANA based system is accelerated by default.
Complex reporting requirements can be difficult to architect on a BW system as a true, performance optimized run-time coding engine does not exist. SAP HANA Calculation Views allow for much more flexibility.

BW using HANA as its database
Custom tables and views
developed with HANA Studio
and ETL with BODS (or other
certified ETL tool)
SLT does not provide a method for performing robust
transformations during loading.
Most appropriate for operational reporting vs.
analytical which typically
requires transformations
Complex reporting requirements may require new
views vs. extending content.
BW Extractors can be used using DXC or ODP API
through BODS.
Flexible ETL (or ELT) process.
Since this method uses more generic Relational DB
modeling, the skill set of
existing staff may need to be
enhanced.
Tools to model, create security, job scheduling, metadata, etc.
are not as robust as BW. Time
to create standards and
governances needed.
BW app server(s) required.
Well known technology with plenty of employees on staff or
in the marketplace that
understand.
Very robust, structured functionality for an enterprise
data warehouse.
SAP has made a commitment to continue to innovate
capabilities.

BICPs Viewpoint
HANA Live is very appropriate for real time operational reporting and for a relatively simple way to bring ECC data to HANA for data marts.
Custom development with HANA Studio and Data Services is a workable
solution, but it does not provide the framework for a robust enterprise data warehouse.
SAP BW Powered by HANA gives the best of all worlds. If you are an existing
BW customer, the next question will be whether to migrate your existing system to HANA or build green-field (well leave this for another discussion).
If the BW solution is chosen, this does not prevent you from building in HANA
Studio when appropriate. This is called Mixed Use Scenarios.

SAP NetWeaver BW Accelerator evolution to SAP HANA
BW Accelerator (BWA) BW on HANA
Data is loaded from BW to the BWA for in-memory acceleration
If indexed in BWA queries see large performance improvements
BW architecture remains unchanged
SAP BW Server
BWA Appliance
Data exists directly in-memory
All queries see large performance improvements
Data loading sees large performance improvements
BW architecture is simplified
Enterprise Edition Includes HANA Analytics Foundation with HANA Studio for next generation analytics
