Basics of Database in SAP
By Ron Victor
SAP like enterprise applications are specifically made up of
programs with the data which are used by and created by those
programs. In a meaningful way the data are organized within in a
database, For the benefit of programmers, which are made easy so
that they can access and find the necessary data to do something
useful, for instance run a financial report or to create a sales
order. The programs and the data will be in same database for SAP
component or product like ECC, Normally each component will posses
its own database (Even some exceptions exists) - a production
system landscape composed of SAP Business Warehouse (BW), SAP ECC,
plus SAP Customer Relationship Management (CRM) consists of three
production databases. Given its basic station in the life of an
SAP system, since it is important we have to understand the over
all role of database.

structures of an RDBMS

Structure of Database A database can be said as electronic
warehouse where we can store information’s in an organized manner
so that the system can find the desired information quickly.
The database is composed of tables, columns (called fields), and
rows (called records or data). A simple example of a database is
telephone book which are organized alphabetically so that it make
the user to get their information very easily likewise the
database is formed with the same concept. Instead of man the
system will do the work so the work can be done easily and
efficiently.
The basic structure of a database is somewhat comparable to a
Microsoft Excel spreadsheet in which columns (fields) store row
after row of records (data). The major difference between a
database as well as a spreadsheet is simply that databases be able
to contain multiple tables that are connected to one another
through relationships. Thus, a database can be thought of as a
much more complex, plus ultimately much more useful, spreadsheet.
The database plays an important role in each SAP system, as it
houses all the data that are used by that particular SAP component
or else product. Several brands of databases exist, making it easy
intended for an IT shop to choose a database vendor with which
they are probably already well-known. Currently, SAP can use a
range of different brand name database releases ranging from very
expensive as well as imminently flexible to very inexpensive as
well as yet quite capable.
It is significant to note that not all database vendors as well as
versions are supported by SAP. SAP is likely to stick with the
market leaders, over the years adding as well as removing support
intended for certain vendors. In this way they not just limit the
amount of database-specific customization they have to perform,
but they endow with IT shops with flexibility plus choices, keys
to success both for SAP as well as the IT organizations tasked
with organize and supporting SAP solutions.
