Answer:

We can group any complex internal data objects of an ABAP/4 program together in data clusters and store them temporarily in ABAP/4 memory or for longer periods in databases. We can store data clusters in special databases of the ABAP/4 Dictionary. These databases are known as ABAP/4 cluster databases and have a predefined structure. Storing a data cluster is specific to ABAP/4. Although we can also access cluster databases using SQL statements, only ABAP/4 statements are able to decode the structure of the stored data cluster.

In the following section a type of data storage is introduced that can only be used by ABAP programs. The content of any number of data objects of any complexity can be stored in different storage media using the ABAP specific format known as data clusters. Only ABAP programs can use this format and therefore only ABAP programs can import data stored in this fashion back into data objects. The following storage media exist: · Byte String · Internal Table · ABAP Memory · Database Tables · Cross Transaction Application Buffer...
