I am new to Qlikview so looking for some "best practice" approaches around date handling.
I have a single database that is a dump of our operational data with very little data modeling going on. We do not have a date table within there.
I would like to bring in operational data and associate it with dates and I'm wondering whether it would be best to maintain a date table within the database or whether I could handle it in Qlikview effectively.
I can see how I can easily create a calendar dimension in Qlikview and map data that has a date stamp on it, but a lot of my data has what I would call effective dates.
So a simple example might be:
a table in the database has employee history information. One of the columns is employment date.
What if I wanted to show a monthly trend over a number of years, showing how many employees were employed for the selected month (effectively a headcount at that point in time)?
One way would be to manage it in the database, but if I created a calendar "dimension" in Qlikview directly is there an effective way to map my data to it?
Thanks for any advice
