BaSyTest SoftwareThe integrated databaseAll data that is used for operation of the system (i.e. battery parameters) and all data measured with the system is stored in a database system. The database system makes it possible to use the well known SQL (SQL-92) database language. In normal cases the SQL commands are automatically generated by the BaSyTest software. However, in some special cases, the user has the possibility to use SQL queries. In most cases the user do not need any knowledge about the database system. The following figure shows the structure of the database.
Each test object (i.e. battery, capacitor etc.) is described by one entry in the battery database table. The database table test-channels describes all available test-channels and the users are described within the user database table. The data measured by tests, are stored in separate database tables. The table tests describes the battery, the test-channel and the user for each test. Additionally information as start- and end-time, name of the test and a comment are stored, too. For starting of a new test, only the test-channel, the used battery and the name of the test-plan must be specified. The database system has the following advantages in comparison to simple file systems:
