The planning of the data Management system in research Studies is evaluated from different aspects. Initially, we delimited some functions and specified its relevant role during all study phases, from the data processing coordinating center point of view. We emphasized over the importance of a close and routinely communication between centers in order to assure minimum deviations from protocol and calendar established. Several components to this system are presented including software and hardware considerations, data quality assurance procedures and monitoring. Finally, we presented some guidelines regarding data base preparation for analysis and adequate documentation of the project. Although this system is presented in general context, it could be applied to research studies on a single center.
