WHAT IS DATA CLUSTER?
HOW DO YOU ESTIMATE THE TIME TO FINISH A PARTICULAR OBJECT?
Answer Posted / amurta
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 illustration shows the schematic structure of
a data cluster in the storage medium.
To store and read data clusters, ABAP offers the following
statements:
· EXPORT parameter list TO medium
· IMPORT parameter list FROM medium
The data cluster is defined with help of a parameter list
parameter list, (see keyword documentation), and specifies
the Storage Medium in medium.
You can write a directory of the data objects of a data
cluster to an internal table using the statement IMPORT
DIRECTORY.. The data cluster was stored in a database table
using EXPORT.
To delete data clusters, you can use the following
statements:
· FREE MEMORY deletes all data cluster from the ABAP
memory
· DELETE FROM ... ID id deletes a data cluster with
the identification id, which was stored in the ABAP memory
of a database table, or in an application buffer of an
application server.
For further details about these statements and additions,
see the keyword documentation.
