QlikView

Visualization, Analytical capability, dynamically change chart type, device adjustment feature for PC and tablets

Technical development and some data modeling features

This is an excellent analytical tool with below best suited features:
1) Flexible chart design
2) A lot of charts and plenty of minutes properties to configure the chart.
3) Power of custom expression using a expression language called "SET ANALYSIS". This enables a better control on data transformation and manipulation.
4) Script editor where in Data Layer can be defined, designed and managed.
5) Nice client server architecture so that report designed can be easily published over to web and access can be controlled easily through management console.
6) Qliksense, a cloud model, is a best thing qlikview has.

It's nothing like bad things but good if it has few features (that other BI tool has)
1) Data management should be more user friendly. Right now it is in script editor. Someone with good knowledge of Relational Database can easily handle this but a programmer knowledge is must. End users or non technical person may timid to start with qlikview as they will find it hard to start with.
2) Too many properties and configuration available. (It's not a bad thing at all as it gives more flexibility) But many configuration can be easily clubbed together systematically and user do not waste time to find the properties configuration. Meaning configuration should be simplified and structured.
3) Desktop should be as neat and clean as qliksense. Qliksense is way par than desktop in terms of User interface.

Qlik gives me customer data from multiple inputs which reduces the search and having to look through multiple sources

The only thing that I would like to see is an integration into my old antiquated crm - sugar. other than that, nothing
