Difference of Qlikview from other BI tools

[#1]

I have good experiance in BI reports analysis and testing. But I am in need to learn about Qlik view and improve my knowledge to be very effectively to involve in various projects of Qlik view.

First can anyone help me in understanding Qlik view and how it is different from other BI tools. May be the question is of very basic, but i like to hear from lot of experts over here. Thanks in advance.

Hi Vignesh

Traditional BI - They have a 2 layered architecture (application layer and database layer)

When you run a report, the data is filtered from database layer and comes up to the application layer. It takes more time. It cannot be realtime.

Qlikview (in memory computing) - Qlikview uses the concept of in memory computing. All data is brought to ram first and then processed. Here, both application layer and database layer are merged. It is very fast. If you want to improve the performance, need to keep on adding rams. It also stores data in an optimized format known as qvd. The licensing fee for this software is less compared to other tools like SAP BO etc.

It is based on html5 and java script

It also supports almost all the databases including web formats like xml and JSON. You can direct get data from websites.

All the best.

Thanks a lot..... Can we call Qlik view as an 3 Layered Architecture ?

For testing do we need to reconcile data of report to data mart ? What all the types of testing that might need to be done specially in Qlik view. For ex : KPI testing, etc.

Do we have a tutorial that helps me in terms of navigation of Qlik view reports etc. As a person very new to Qlik view, can you suggest some course to improve my knowledge ?

Hello,

Hi there if you're started I recommend the following book http://market.qlik.com/qlikview-11-for-developers.html this from the start with examples and real data, that you practice.

Hi, Vignesh.

There are a number of posts in this forum comparing QlikView with other BI tools.

Examples are as follows:

Re: Qlikview Vs Crystal Report

Re: Qlikview vs SAP BO or Cognos.

Re: QlikView Vs Tableau

Hi Vignesh and welcome to QlikView!

Since you have previous experience in other tools, I would recommend you to read QlikView: Against Intuition | Lucian Cotea to understand the differences.

Hi Neil,

do you know if there is also something around here on how to find good arguments for QlikView, in particular in terms of any "added value"?

-- The background is this: In my company, we have QlikView for a while now and it's running and I get positive feedback from the users, too. They like it. The issue is, we have
   very many issues in all kinds of places - not QlikView - so budget is tight and every cost_factor is naturally
  being looked at.

- Also, in a group like ours, there should actually be no "individual solutions" used by only one branch - so there are only two ways in the long run. Either we spend more and  build our QV_infrastructure beyond this branch or we leave it.
<=> The issue is, management likes things that can  be measured - every tool has to deliver an "added value" that can be measured - but QlikView is "only" about visualizing data that was there beforehand - so how to measure that? Of course it is much preferable to view your data in a nice diagram than to look at an Excel sheet and it is also easier to memorize, but that is hard to put down in numbers ...

I worked with a data analysis_software before, there we had something in the background - usually we were looking for "anomalies" which the company could then use to save money - voila, something measurable.

But we don't use QV for analysis, we just use it to visualize the data.

Also, there is no point just comparing QV to something else - well, comparing to CR would make sense for we have that around, too, but primarily, it is a question of finding arguments for the value of having QlikView at all.

Thanks a lot!

Hi, DataNibbler.

I've been in several big companies where everything has to have a measured value. It can be difficult, especially if they are not using QlikView to it's full potential.

You can ask a lot of questions. . . .

Is the cost of providing insights to the business less than before?

Is information more accurate now that user intervention is removed?

Is information available quicker than it was before and can the time saved be calculated?

Are reports more relevant as they focus on the heart of the problem that the user is having?

Are insights available in an easier format, thereby growing user adoption?

Are people making better decisions as they are focusing on the right issues?

. . . .but they can't easily have a monetary value applied. Is there a way of expanding what QlikView can offer the business beyond replacing excel visualization and get management buy-in ?

Neil

Hi Neil,

thanks a lot! That points me in a direction already.

User adoption, in particular, is one of the points I think we can focus on - it is now definitely easier for the people to see all the data relevant to their respective team and it is just a lot nicer, which facilitates user adoption.

Also, the time that team_leaders spend daily putting together all the information they need for team_meetings is definitely less now in many areas.

And yes, of course there are a lot of things we could do using QlikView to offer more value to the business - we could start using alternate_states for some what-if-analyses and we could generally go more into data_analysis - but we don't have the manpower to develop those things.

Well, I don't have time to worry too much about that know. We'll sort this out once the management's eyes are on our branch once again and we have a chance to convince them of the value of promoting QlikView.

Thanks for now!
