Today's medium-sized and large companies tend to have a very complex corporate IT infrastructure, which has to be continuously adapted to the fast-changing business needs of the company.
Applications integration presents Solutions to problems emerging in four basic areas:

Operation
Badly organized IT systems are often developed in an ad hoc fashion. This presents extremely complicated and entangled architectures, which are extraordinarily difficult and costly to maintain.

Corporate Data Management
Companies and public administration authorities usually create a vast pool of data in the course of their everyday functioning. In the majority of cases, this data is stored in systems that are only loosely connected or not connected at all.
All too frequently, the same data content will be found in more than one location, perhaps under different names. This makes it difficult to interpret, correlate, interconnect, manage, and ensure easy communication between such data.

Corporate Processes Management
Administration and business processes represent the most valuable asset of a company, so such processes should be managed in centralized and integrated ways, and should be explicitly represented in IT systems.
In the existing systems, however, such processes are only implicitly represented. They can be scattered according to the internal logic of individual applications, or worse still, stored only in the minds of the company's employees.
The various processes thus fail to be represented in a coherent and manageable form.
As a result, the efficiency of the company's operations cannot be kept track of and often cannot be improved.

Development and Expansion
In the case of the complicated and badly organized IT systems described above, further development and expansion proves to be extremely expensive, since the modification of one architecture component will usually affect the operation of the whole system. Without a well-defined IT strategy, any further developments of the system will lead to increased confusion and an even more complicated architecture.

The solution to the above problems is the implementation of a new IT strategy based on the integration of applications.

The technical solution used in the integration of applications includes the following features:

• It is based on a tool that can form the basis of the company's information technology infrastructure, thus providing a reliable, flexible and scaleable framework system.

• It enables the user to manage business processes in a centralized, integrated and coherent fashion, and to query the statistics created in the course of running these processes.

• It is capable of interconnecting systems and processes.

• It is of a simple construction, it is highly centralized and easily manageable.

• It is easy to modify and optimize.

• The costs of introducing and operating new applications are low.

• After its implementation, the existing systems are not dismantled but they keep being used.
