Get started with developing qlik datamodels

Compared with many other tools it's quite simple to start with Qlik especially if the datamodels are simple with only one/two tables. But this advance even increased if the requirements became more complex.

It's already possible with only little know-how to develop quite sophisticated data-models. Basis is the associative data-model from Qlik whereby all tables will be connected through key-fields whereby synthetic keys and circular references should be avoided. Thoughts about star- vs. snowflake-sheme, normalization and so on can be widely employed back - it's easier as it looks like:

Circular References

The Table Viewer

Synthetic Keys

Merging Data from Multiple Sources

Fan traps and Chasm traps

Don't join - use Applymap instead

Concatenate vs Link Table

Fact Table with Mixed Granularity

If data don't be loaded from databases else from flat-files they have often problematic data-structures including the lack of data. Beside the following links is the inbuilt file-wizard from QlikView a powerful but not well documented tool - helpful is here the book: QlikView 11 for Developers which is in general very much recommended:

The Crosstable Load

Counters in the Load

Generating Missing Data In QlikView

Most often worked the loading from fields without any problems - if not are these links helpful:

QlikView Quoteology

Automatic Number Interpretation

On Format Codes for Numbers and Dates

Further very helpful is the use of a master-calendar within the data-model:

How to use - Master-Calendar and Date-Values

Here you will get further important topics: Advanced topics for creating a qlik datamodel andMore advanced topics of qlik datamodels.

Beside the above used links you will find many interessting postings here within the qlik community to these topic - the notes here are a good starting point to go further.

Have fun!
