4. SAP HANA Extended Application Services
overview
Rationale: Enable application development and deployment – minimize
“layers”
 with an http-based UI (browser, mobile apps)
 to run directly on SAP HANA, without an additional external application server which
minimizes TCO
 leveraging the built-in strengths of SAP HANA for the best possible performance
Scope
 From lightweight environment for small web-based applications
 To robust environment for complex high-speed business applications which utilize the
deep integration with the differentiating SAP HANA database features

5. ABAP and SAP HANA Extended Application Services strategic
usages
ABAP SAP HANA Extended Application
Services
• Support HANA specific features plus a
variety of traditional Databases • Applications built to run only on HANA
• Available now (BW 7.30, Gateway 2.0 • Planned Availability in HANA 1.0 SP5
SP4, Accelerators)
• New applications
• Continues innovation of current
applications

Programming Model

14. Programming model –
paradigm shift: responsibilities in runtime layers
Classic NW ABAP Layers XS Applications
SAP GUI Browser
Display pre-rendered UI Complete UI Rendering
Proprietary Protocol
HTML5: Javascript execution
ABAP
http(s); OData (pure data only)
UI Rendering HANA
XSEngine
Application Logic Procedural Appl. Logic
HdbNet
DBI/DBSL, DB buffer (minimal data volume)
SQL IndexServer
Other RDBS Data-oriented Appl. Logic
SQL
(high retrieval load, no scripts)
(HDB-SQL, SQLScript)
© 2012 SAP AG. All rights reserved. 14

15. Programming model
UI Rendering should be implemented completely in the Client
 Server generically supports data exposure (via OData) and static UI content provisioning
 Browser-based applications should use HTML5, especially SAP UI 5
 Ability to leverage the Open Social component model
 Additional UI features provided by the Portal Services: navigation, page building, mash-ups, personalization
Server-side procedural logic in JavaScript
Data-intensive logic to be pushed down to the index server processes via Native SAP HANA
View Types or SQLScript
Application artifacts are stored in the SAP HANA Repository
