  The new PostgreSQL database is developed for systematization and unification of the data archiving and observation at the VEPP-4 facility. About three thousands parameters are set and checked for the VEPP-4 control. The current values are read from the control and measuring electronics and stored into the many files with different time of storing. The storing intervals vary from one second for the pulse systems to several minutes for the slowly changing parameters. Parameters are transfer to the database as soon as they are renewed in the source files. Twelve independent processes running under Linux provide the permanent data transfer from the files with current values to the database. The graphical interface is developed for user’s access to the database. It provides observation of the stored data in graphical or textual form and monitoring of the current parameter values. The interface allows us to observe any collection of parameters in a single or in different windows for any period of time.
