Data groups represent a database table. You can reach the
of a data group from the
The data fields of a
data group can be shown via the
Edit menu / Show data fields,
if the data group is selected in the application structure.
If you select a data group, you can create edit pages, view pages, view pages with elements,
child data groups, data fields and references via the
New menu or context menu.
An existing data group, including all pages, data fields and references it contains,
can be deleted by selecting "Delete" from the
Edit menu or context menu.
Only one data record may be saved in a system data group. The system data group
is therefore well suited for saving application-wide constants, such as
a fixed investment amount after which an approval is required, or the
activation of an audit trail for the releasing of documents or the saving
of email address that are used in the application. One only system data group
can be saved in each application; this is created from the
application node. The data in
a system data group has validity application-wide. They can be used in
all data groups of the application. The values of a system data group are
saved in the database table LCAPPPROPS under
the application GUID.
If an edit page is integrated into the application menu,
the system data group's data can be edited very easily.
The values in the database table LCAPPPROPS
may not be modified. United Planet assumes no responsibility for
erroneous changes, e.g. those performed by a process that writes
to the table.
4. External data groups
External data groups integrate data from external data sources.
They can be created via the New menu / Data group
when the application node
is selected. More information about creating a connection to an external data source is available
5. Child data groups
If you select an existing data group in the
you can create a child data group via the
New menu / Data group.
child data groups serve to create so-called
parent-child relationships. In practice, these data
relationships will be used when master data in the superordinate data group is linked
to multiple records in a child data group (such as product groups that
may contain multiple items). Intrexx provides the ability to create these
links with the click of a mouse and without requiring special programming knowledge. By
moving from a parent data record (e.g. from a view table) to a page in the child data group, the
relationship will be created automatically.
