Database View in SAP ABAP
As the name suggests Database View in SAP ABAP is a view that integrates several distributed database and helps us to view all data at one place. We can access data of Database View using SQL commands (SELECT Statements). It implements inner join for integration. It can even contain a single table without any Join statement. And if there is only table then we can maintain data also otherwise we can just read only.
A Database View in SAP ABAP is a view which combines multiple tables in to a single View and is used only to read the records.
*NOTE: If only one table is there then it can be maintained too.
