• Key Concepts: 
  A logical database is a component of the ABAP Runtime Environment (BC-ABA) in SAP. It is a collection of tables and views that are logically linked together to provide a consistent view of the data. Logical databases are used to access data from multiple tables in a single statement, making it easier to write complex queries. 
  
  How to use it: 
  Logical databases can be used to access data from multiple tables in a single statement. This makes it easier to write complex queries and reduces the amount of code needed to access the data. To use a logical database, you must first define the database structure in the ABAP Dictionary. Once the structure is defined, you can use the logical database name in your ABAP program to access the data. 
  
  Tips & Tricks: 
  When using logical databases, it is important to remember that they are not physical databases and do not store any actual data. Instead, they are used to access data from multiple tables in a single statement. It is also important to remember that the structure of the logical database must be defined in the ABAP Dictionary before it can be used.
