Retail presentation manager
The retail presentation manager (RPM) is provided as a uniform tool
(MS-DOS and UNIX) for input and output format specification. The
RPM significantly reduces the development outlay for POS applications.
Retail transaction manager
The retail transaction manager (RTM) forms the link between the POS
application and the operating system. The RTM allows the accessing of
shared data, including price lookup and the maintenance of transaction
files.
High frequency table
The price look ups (PLU) in the retail area are performed using the
High Frequency Table (HFT). The HFT provides functional libraries with
uniform interfaces for this purpose.
Hash file access method
Similar to the HFT, the Hash File Access Method (HSF) is primarily
used for price look ups. The extensive article data on the mass storage
can be managed with HSF. To this effect, the article file is specially
structured when it is created. This structure, in conjunction with the
access method for “hash” files, provides particularly short search times.
