That certainly depends on what you want to achieve with your data. If you already have a preaggregated table in SQL Server DB which you want to display one-to-one on a web page via Java Script - just go ahead and create your webpage - you don't need QlikView for that.
If, however, you need fast in-memory aggregations on the fly and calculations which will react to filter selections e.g. - then you might use the QlikView engine to achieve that and possibly present the results in an extension object. In that case, though, I would always urge you to have a look at presenting the data in a native QlikView object. Either way, you'll need to go and implement your solution within a QlikView document hosted on a QlikView Server.
Hello Martin, thank you for the reply.
The application I am trying to do this for is already created in qlikview. I have built an extension in JS and integrated it fine.
The app is pulling the data from an SQL Server DB and I understood it stores it in Qlikview memory. I want to make use of that data in my JS so I can display different stuff.
For example this is how the data is loaded in some of the other pages:
TeamName as Team,
And I want to make use of this in my script.js file - store them in some variables and then be able to play around with them.
