A schema is just like a database folder.The relavant tabels are
going to group together according to the particular
schema definition.
There are 3 types of schemas.
1. 1. User Defined Schema
2. 2. System Defined Schema
3. 3. SLT Derived Schema
User Defined Schema is created by user (DBA or System
Administrator)
System Defined Schema Where all the list of tables views going
to be associated.
There are 5
a. a. _SYS_BI
b. b. _SYS_BIC
c. c. _SYS_REPO
d. d. _SYS_STATISTICS
e. e. _SYS_XS-ENGINE
SLT Derived Schema :When we configure the SLT first time(by
administrator) they are going to give schema name--
>meaning a configure name and that configure name that is
provided or configure out side the HANA in the source
system or in the SLT replication server.That particular name is
container of list of the tables that need to be pulled
from the source system.
SYS_BI: This schema stores all the metadata of created column
Views.
_SYS_BIC: Whenever we activate HANA Models, its going to be
stored hear in _SYS_BIC System standard schema
_SYS_REPO: Whatever the objects are there in the system is
available in repository
_SYS_STATISTICS: All the system configurations and
parameters.
_SYS_XS: XS stands for XML Server engine. All the 3rd party Web
Services can Connect & Communicate.
