In contrast to multi-dimensional data storage with InfoCubes, the data in the ODS object is stored in transparent, flat database tables.

Data Element: It is an intermediate object between domain and table type
Domain: It defines attributes such as length, type, and possible value range
25. Mention what are SET parameters and GET parameters?

33. Mention what are internal tables, check tables, value tables, and transparent table?
It is the standard data type object; it exists only during the runtime of the program.
Check the table will be at field level checking.
Value table will be at domain level checking
The transparent table will exist with the same structure both in the dictionary as well as in the database exactly with the same data and fields
