3. SAP HANA Application Services:
Overview

4. HANA 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 HANA Database 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 HANA Database features

Programming Model

11. 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 (HDB-SQL, SqlScript)
(high retrieval load, no scripts)
