Answer / niki

ADABASE the adaptable database, is a high-performance,
multithreaded, database management system for mainframe
platforms where database performance is a critical factor.
It is built on INVERTED LIST model.

Inverted List: it is used to resolve Adabas search commands
and read records in logical sequence, is built and
maintained for each field in an Adabas file that is
designated as a key field or “descriptor”.t is called
an “inverted” list because it is organized by descriptor
value rather than by ISN.

ADDRESS CONVERTOR:it contains the RABN's in ISN order. It
determines the physical location of a record. It is an
index that maps the logical identifier of a record (that
is, the ISN) to the relative Adabas block number (RABN) of
the Data Storage block where the record is stored.

DATA Storage:It stores the actual record in the order in
which it was entered
