Retail presentation manager
The retail presentation manager (RPM) is a standardized tool (MS-DOS
and UNIX) for input and output format specification. The RPM significantly
reduces the development outlay required for POS applications. For more
information, contact your WN branch office.
Retail transaction manager
The retail transaction manager (RTM) forms the link between the POS
application and the operating system. The RTM allows shared data, inclu-
ding price look-up data, to be shared and transaction files to be main-
tained. For more information, contact your WN branch office.
High frequency table
Price look-ups (PLUs) in retailing are performed using the high frequency
table (HFT). The HFT provides function libraries with uniform interfaces for
this purpose. For more information, contact your WN branch office. Software
Hash file access method
Like the HFT, the hash file access method (HSF) is primarily used for pri-
ce look-ups. The extensive article data on mass storage media can be ma-
naged with HSF. To this effect, the article file is given a special structure
when it is created. In conjunction with the access method for “hash” files,
this structure ensures very short search times. For more information, con-
tact your WN branch office.
