Databases HP ALLBASE/4GL allows you to define the components of an HP TurboIMAGE/iX database in HP ALLBASE/4GL and maintain an HP TurboIMAGE/iX database using HP ALLBASE/4GL applications. You can use a maximum of 255 databases in a single HP ALLBASE/4GL application. Each database must be defined and linked to the application by the HP ALLBASE/4GL administrator in the administrator application. The name and location of the database in the file system is part of the database definition. Unless the HP ALLBASE/4GL administrator specifies a fully qualified database name (that is, a name in the form FILE.GROUP.ACCOUNT), HP ALLBASE/4GL appends the current value of the HP4TIPATH system variable to the external name of the database to identify the group and account of the database. If HP4TIPATH is not defined, HP ALLBASE/4GL searches for the database in the user's current group and account. Commonly, application developers will create HP ALLBASE/4GL applications to access existing HP TurboIMAGE/iX databases. HP ALLBASE/4GL provides several utilities so that you may load data set, data item, and database definitions into an HP ALLBASE/4GL application. This means that your data set definitions, record layouts, and field specifications do not need to be redefined in HP ALLBASE/4GL. The upload utilities are described below.
