Comarch Service-Agnostic Transaction Engine is a component specialized in processing information about various transaction types. Processing can be configured using rules and may include configuration for data loading , pre-processing, rating / pricing, aggregating, statistic building, correlating with other events and storing in the database.

1. Comarch Service-Agnostic Transaction Engine
Overview
Comarch Service-Agnostic Transaction Engine is a component specialized in processing information
about various transaction types. Processing can be configured using rules and may include
configuration for data loading , pre-processing, rating / pricing, aggregating, statistic building,
correlating with other events and storing in the database.
The Transaction Engine can process the data in real-time as well as in batch mode.
Many Comarch customers (including Polkomtel, Bouygues, Auchan Telecom, NASK, TP S.A. ) are using
the Transaction Engine (also called Data Processing Server) as the important part of their BSS
solutions for processing millions of events every day.
Comarch Service-Agnostic Transaction Engine can be used in many different industries:
• In the Telecommunications industry as a convergent, real-time and mass rating /
charging engine used for both B2C and B2B relationships;
• In M2M solutions as an M2M Transaction Gateway;
• In Utilities as a Transaction Engine for rating / pricing of events;
• In Finance as a Transaction Engine for rating / pricing of financial transactions.

2. Features
In many cases, event processing is connected with rating, although the component may perform
many additional user-defined calculations which are not solely connected with calculating the price
for events but may for example correlate events, calculate taxes or make other decisions based on
decision trees.
When it comes to its most commonly used feature - rating - it supports multiple pricing models:
• From flat-fee to usage-based fees;
• From market segmentation to custom pricing;
• Product bundling;
• Cross- and volume discounting;
• Rule-based models for custom pricing scenarios.
The main advantages of the Transaction Engine are its performance and flexibility. However, the
scope for processing the events in both real-time and batch mode grants numerous additional
benefits.

Real-time processing is supported by specialized interfaces, that can be used for real-time interaction
with elements producing events. Depending on the industry it can be e.g. Diameter Ro for integration
with network elements in the Telecommunications industry, Java for integration with the Financial
Transaction Server or the CORBA interface for M2M or Utilities.
Batch processing is dedicated to dealing with huge volumes of events loaded from files. The
Transaction Engine manages file loading processes and allows administrators to review data
processing as well as to correct events or even re-process particular packages of events. In this mode
it is also possible to perform very complex calculations that reuse existing calculations, aggregates or
values from external sources.
Comarch applies the best possible technology to the needs of a specific market segment.
Consequently Java and relational databases are used as core technologies for most Comarch
products. However, when it comes to processing millions of events per day, responding to requests
in only a few milliseconds and guaranteeing a genuine, high-availability, reliable technology is
essential.
The Transaction Engine technology includes the C/C++ programming languages, file databases for
high performance data storage, optimized thread management, shared memory, advanced
techniques for mass data writing and simultaneous data reading.

3. This multi-threaded component works in the UNIX/Linux environment and allows parallel processing
of events. The kernel of the Transaction Engine is constructed to allow expansion of the system
functionality through standard or customized plug-ins.
Benefits
The processing chain can be configured with easy-to-use decision trees. The possibility of using rules
and the same configuration methodology for real-time and batch processing is unique and gives you
more than similar solutions offered on the market.
Additional benefits of the solution include:
• Multi-industry – you can use the Transaction Engine in multiple industries and business
models: Telecommunications, M2M, Utilities, Financial and more;
• Multi-service – the flexibility of configuration enables you to use the engine for transactions
related to multiple services offered by institutions or service providers;

4. • Scalability – lets you process high data volumes with parallel implementation of Transaction
Engine instances;
• Flexibility – provides you with rule-based configuration for real-time and batch processing;
• Service continuity – gives you constant upgrades and high availability of services;
• Stability – advanced technologies, development and testing practices leave you confident
that the services are stable;
• Error prevention – versioning of the configuration with version acceptance and undo
features.
