This is even more important because the implemented exchange mechanisms are most often asynchronous. When two applications exchange information in synchronous mode, they are connected to each other. If one of them becomes unavailable, the other immediately detects that fact, and executes the instructions planned for such a case. For example, it posts an error or alert message informing on the non-response from the application partner. In an asynchronous exchange mode, applications are not informed of problems that can arise during the exchange.

In addition, each item can be repeated several times to constitute the data for the next level up. This tree or hierarchical type format mixes the formats described above, as shown in this simple example: keyword1=(datum 1, datum2,keyword11=(datum 11a, datum11b),keyword5=datum 5),keyword 7=datum 7, .... It is obvious that for this type of format, locating the data continues to complicate the analysis, and therefore degrade performance yet again. XML formats In the family of hierarchical formats, XML (eXtensible Markup Language) is a standard from the W3C (World Wide Web Consortium), the consortium that groups public and private users with manufacturers and suppliers of the computing Levels in Integration Services 55 technologies on which the Internet is founded.

Database management systems The DBMS (database management system) constitutes a way to transport data between applications, since it offers basic replication mechanisms or inter-DBMS access bridges (gateways). 1), essentially projects of integration through data propagation or integration of composite applications. In most cases, the semantics and the data models used by the applications to be integrated are compatible.
