6.Search Helps
7.Data element

We will study further about above Objects in detail.

1. Tables

Table is independent in the data dictionary and it stores the real time data .It is defined with fields that are columns and rows and fields can be defined with their data types and lengths.simply table contains following components .
1 Table fields
2 Foreign Keys
3 Technical settings
4 Indexes
and also we can modify tables using Append structure and  include structure.

Example Table:



Tables which  stores in the data base like  the below picture
SAP Programming Language



2.Views


Simply Views are like tables and contains the Fields that are from different tables but views does't store physically in the database and the data of view is derived from different tables.
views contains the base tables which must be linked by joining conditions and we must be select views fields from base tables and also we should use selection condition to filter the records of views. .


SAP Programming Language


Views are four types:
Database views are implemented with an equivalent view of the database.
Projection views are used to hide fields of a table.
Help views can be used as a selection method in search helps.
Maintenance views allow you to maintain the data distributed to several tables for one application object at a time.

SAP Programming Language is SAP ABAP which is used to develop SAP standard and Custom Applications .These applications are created in ABAP Workbench Tools.

ABAP is a 4th Generation Language ,independent from all Data base systems.

Example SAP ABAP(Advanced Business Application Programming) Programming syntax:

report zhello.
write: / 'hello world'.

 Output : hello world.

SAP ABAP Programming Language is not case sensitive .

Every statement starts with Key word and Ends with Period(.)

Learning ABAP (SAP programming Language) is very easy .but SAP software is not a Open source tool which You have to purchase it from SAP Support Downloads .
