Performance of TOMAS is far better than performance of any other system on the market.. In the same time, TOMAS costs are only fraction of the cost for comparative information system. Hence, the new quality of the system is achieved. Here, it is described how that has been achieved.

DATABASE AND PROGRAMS RESIDENT IN CENTRAL MEMORY

Since the beginning of 90-ties, computers are using very large central memories. This trend continues, i.e. central memory is all the time bigger, faster and cheaper.
This trend is used in the design of TOMAS, so that it operates in the following way:

Programs and complete user database could be resident in central memory, as long as TOMAS is active. Hence, complete operation is done between central memory and processor, so there is no need to access disks.
Other solutions on the market keep the user database stored on disks and the speed of operation is largely limited by the speed of disks.

In this way, processing speed is increased cca 15 times (1.500%).

INFORMATIONBASE

Use of the concept of informationbase further increases efficiency of TOMAS, in the following way:

• information is largely produced automaticaly, without work of employees and after work hours, i.e. so that computer capacity is free for daily operations

• information is available to all authorized users, i.e. information is not made repeatedly for each user.

TOMAS operations are optimized in various ways:

• database structure is optimized

• access paths fo rdata retrieval are carefully chosen in all options

• most efficient algorythms for data handling are used.
