Generic databases

A generic database is a table in which the field names are stored as field values in one column, while the field values are stored in a second. Generic databases are usually used for attributes of different objects.

Look at the example GenericTable below. It is a generic database containing two objects, a ball and a box. Obviously some of the attributes, like color and weight, are common to both the objects, while others, like diameter, height, length and width are not.

On one hand it would be awkward to store the data in a way giving each attribute a column of its own, since many of the attributes are not relevant for a specific object.

On the other hand, it would look messy displaying it in a way that mixes lengths, colors and weights.

If this database is loaded into Qlik Sense using the standard way and the data is displayed in a table, it looks like this:

However, if the table is loaded as a generic database, column two and three will be split up into different tables, one for each unique value of the second column:

The syntax for doing this is simple, as shown in the following example.

Sheet1:
Generic Load * inline [
object, attribute, value
ball, color, red
ball, diameter, 10 cm
ball, weight, 100 g
box, color, black
box, height, 16 cm
box, length, 20 cm
box, weight, 500 g
box, width, 10 cm ];
