2.8.1 Purpose

In the database management, the individual database tables are organized in groups. Existing databases can be edited and new ones can be created. The wizard is started via Extras - Manage Database and may remain open at the same time as VCmaster. 

For more information about querying information from databases refer to Chapter 2.7.

2.8.2 Structure of a Database

The database table consists of input columns and one table header. The table header contains the variables of the columns, each with three parameters. Linking the desired value with specifications in the text is done via variable name. For an improved overview, a label without any impact on the search may be specified. If a unit of measurement is specified, it is returned with the associated value of the variable. 

Important: Define a variable as text with "Tx" or as interpolatable with "in" in the Attribute field.

Note: Greek characters are spelled out in full in the table header. For example a query can search for "σW" in VCmaster and will find the associated entry "sigmaW" in the table. A diameter symbol is specified in the table as "Æ" (ALT+0198). VCmaster converts this automatically into a "ø" when inserted.

2.8.3 Interpolation of Values

The equals sign "=" is required in the specified condition. If ">" or "<" is specified, the database table provides the next value without interpolation.

If "kd = 3.22" is specified as the condition and "C25/30" as concrete, VCmaster determines the return value for ks1 as 2.39

Important note on data transfer from other programs:
External digital spreadsheet data can be imported into VCmaster using the standard clipboard feature. Since each data collection can usually be exported using the clipboard, VCmaster databases can be created without manual data input, if digital templates exist. Only the variables and attributes need to be specified.
