6. SAP HANA in Cloud is offered as
a comprehensive infrastructure
combined with managed services.
1. SAP HANA One
2. SAP HANA Cloud Platform
3. SAP HANA Enterprise Cloud.

9. To get benefits of the high-speed in-memory
execution of SAP HANA
OPEN SQL
Unified data modeling and definition with
CORE DATA SERVICES
ABAP managed data base procedures.

12. SPS 05 for SAP NetWeaver
7.4 introduced the new
syntax for Open SQL
which includes support
for comma separated lists,
enhanced string
expressions, the definition
of host variables in a more
standard fashion, and
fewer restrictions for joins
13. Data modeling is often first step in database design and
oop as designers first create a conceptual model of how
data items relate to each other
Involves a progression from coceptual model to logical
model to physical schema.
14. Data modeling is a process used to define and
analyze data requirements needed to support the
business processes within the scope of
corresponding information systems in organizations.
15. CDS is a data modeling infrastructure for defining and consuming
semantic and reusable data models on the database, rather than on the
ABAP server, regardless of the database system used.
16. CDS views are defined using the CDS editor in
ABAP in Eclipse
17.
18. Database procedures are programs that can be called up from
an application program in the same way as an SQL statement.
A database procedure can contain several SQL statements
and series of control structures. You can program loops or
branches, for example, within a database procedure.
ABAP Managed Database Procedures are a new feature in AS
ABAP allowing developers to write database procedures directly
in ABAP first introduced with SAP NetWeaver AS ABAP 7.4.
Database Procedure as a function stored and executed in the
database. The implementation language varies from one
database system to another.
19. In SAP HANA it is SQL Script. Using AMDP allows developers
to create and execute those database procedures in the ABAP environment
using ABAP methods and ABAP data types.
20. AMDPs are wrapped into regular global ABAP classes.
In this example we have created a database procedure for SAP HANA (FOR HDB) using
SQLScript (LANGUAGE SQLSCRIPT) which simply selects the company name
for our top business partners. The number of business partners to be selected
is passed as an input parameter (iv_number) which is used in the SQL Script statement.
