Performance and scalability are two aspects that play a pivotal role over a system’s entire lifecycle. Seldom do requirements placed on a system at the beginning stay the same. If the system no longer keeps pace with performance due to changes in requirements over the lifecycle, this can lead to unplanned and partially also unpleasant additional costs.

The Comarch Semiramis architecture is structured so that it can grow in line with your requirements at any and all times.

Comarch Semiramis can be broken down logically into the following layers:

• Data management
• Applications logic (including web server)
• Graphic user interface (web browser)

The result of this separation alone is an outstanding scaling option. All three different layers can be allocated physically. The Comarch Semiramis applications logic can be installed on any number of computers in accordance with the workload in order to achieve load sharing.

In most 3-tier architectures, data management cannot be allocated, and it therefore represents the limit of scalability. This means that when the database server is operating on the largest possible hardware and this hardware reaches its limits, scalability has reached its maximum limits, too.

Here, Comarch Semiramis goes one step further. Data management has been partitioned once again logically to even offer scaling options on the data management level as well. Comarch Semiramis data have been allocated to altogether 3 logical databases in accordance with their specific application.

These are: 

• Configurations database – system configuration, information
• Repository database – applications code, development objects, meta data
• Online Transactions Database (OLTP) – master and movement data, customizing data
• Online Analytical Processing Database (OLAP) – analyses and statistics

In large-scale installations, as opposed to other systems, this partitioning can also lead to the realization of an even higher scalability.
