TOMAS - COSTS OF
Minimization of TOMAS' total costs of ownership
is achieved in the following ways:
TOMAS uses computer resources very economicaly:
Average database record size is cca 200 characters.
That is much less than in most of other systems on the market. Hence, decreased
load of internal, local and wide area communication channels, i.e.
Average size of program unit is cca 100 Kb
(on RISC computer). Besides, programs operate in the so called "shared
mode", i.e. all users use the same copy of the program simultaneously.
Hence, requirements for central memory are minimized.
Program operations are carefully optimized
- by organization of the database, using shortest database search paths,
using most efficient algorythms etc.
The whole database and programs are resident
in the central memory. This is made possible due to previous properties
of TOMAS. Operating in this way is some 15 times faster than in usual way,
i.e. having database on disks. Hence, due to this factor, TOMAS operates
15 times faster than other systems, because the computer operations are
not any more done retrieving data from disks but rather from central memory.
Hence, the complete operations are done with the central memory and processor,
i.e. by far the fastest components of the computer.
Informationbase concept makes possible:
major part of information is produced after
normal work hours, when most of users are not active
once produced, information could be used by
unlimited nr. of users ... hence, the load of the computer is very much
The resut is - exceptional efficiency and
minimal requirements. The smallest COMPAQ - ALPHA computer one can
buy, could work with hundreds of work stations using TOMAS.
Use of TOMAS does not require investment
in any other software, such as:
DBMS software, for TOMAS has its own DBMS
compiler, for TOMAS is installed as machine
There is no need for specialised computer
personnel, for TOMAS operates fully automatised, there is no need for
human intervention for years.
There are vast possibilities for adjustments
of TOMAS, that the user could make without programming, without additional
Therefore, allthough TOMAS has top
class capabilities, cost of ownership is lower than with most modest PC
Comparing to market leaders, TOMAS costs
dozens of times less and still, has far better capabilities.
