Evolution of database systems is reviewed. We nominate some of the application categories of computer technique, in expert systems and other types of data systems dedicated to performance sporting and competition activity, as well as to complementary activities to professional sport. We introduce a software system which integrates information about top competition activity in a sports discipline, to be installed and updated within a dedicated federation Web site. Intermediate results and game events are on-line registered by using measurement equipment connected to the system and log booked for later processing. From the sporting point of view, final main results serve to the record booking, while statistic data will help making the short, medium and/or long term training programs. The application project sustaining the paper is dedicated to tennis and international and/or internal competitions and achieved in Microsoft Access, a flexible and accessible object-oriented, relational database management system. A Web interface is integrated to the database, providing the Internet access to currently updated information. \itemrv{~} \itemcc{} \itemut{system information; object-oriented relational databases; Internet; performance sports; competition activity} \itemli{} \end
