Gephi vs. QlikView

If anyone ever asked me "what mathematical graphing tool should I use", Gephi would be my first answer. At the very least, it's an excellent prototyping tool. I would be wary, however, if someone needed to use the product for large scale production output. It's finicky at times and does require a little "jiggling of the handle" to get things to work, but I'm sure the kinks will be worked out as the product matures

Sales data validations have helped manage our justifications in the past, especially with regard to new product development and new business introduction. It has also been helpful in identifying trends with business impact and direction specific to quarter and monthly sales from ERP data as well as decisions to purchase equipment of staffing based on run rates and product demand.

One thing that can get out of hand is data output - if you aren't careful in your query, you may be overloaded with data dumps and drown in the amount of info you have to filter through. This is a user caution, not a comment on the software itself.

• As far as my experience gephi provides good mathematical results in calculating Metrics
• Its helpful as we can directly import our data which is in a .csv file
• Saving the analyzed data to a .csv is a plus. Its easy to run all the metrics by single click
• We can filter the columns of metrics and we can export only those we need.

• QlikView has a simple, relational data model that's REALLY fast. Filtering and changing data is dead simple results are almost immediately available.
• The free version of Qlikview is almost completely featured, so you roll a pro-level product out to an entire department for really cheap.
• QlikView is really flexible--if you can imagine it, you can build it.

• A friend helped me to import that data -this process was outside my expertise.
• The UI took some time getting used to. I spent a while formatting my graph before I could really obtain a good view of the network.
• I would like an easier way to organize the different views of the data, I had a lot of tabs open that quickly cluttered my workspace.

• We found that QlikView can be a bit slow in supporting some forms of encryption. It is web-based and we needed to upgrade all of our server to not support the older SSL and TLS 1 protocols, only support TLS 1.2 and TLS 1.3. However, QlikView could not run with TLS 1.2 and TLS 1.3. We had to wait over six months to get a version that would handle the newer TLS versions.
• There are so many options with QlikView that you can get lost when developing a visualization. There are still items I have not yet figured out, such as labeling a graph with the name of a selected detail item.
• QlikView works by pulling the data it is going to use for visualization into its database. I am a security reviewer and I need to make certain that PII and PHI is not pulled by QlikView for a visualization, otherwise this could become a reportable indecent.

While Gephi isn't perfect, it's a powerful tool for mathematical graph modelling that's hard to find in other products, particularly by way of its interface. It grants non-software developers access to a point-and-click way of creating accurate, beautiful visualizations that would normally take hours in other applications. The fact that it allows for live streaming data is also something that's hard to come by, at least for visualization software

Ease of use, ability to load from pretty much any data source. today I created an application that loaded time sheets from excel that are not in a table format. With Qlik's "enable transformation steps" I was able to automate loads of multiple spreadsheets and multiple tabs easily. Could not do that with any other tool.

Gephi is very intuitive and the fact that it shows its process helps the user understand what's going on. However, the animation features can really slow it down and there isn't a way to shut them off. Furthermore, the failures on saving mean you frequently have to start over. These problems disrupt the workflow and can be frustrating.

I do think there is a steep learning curve to the program and that it requires a high level of experience or a data scientist background to fully take advantage and implement dashboards, and users will require ongoing training to maximize ROI, but it is absolutely worth it considering the impact it can make on an organization.

QlikView server is very stable, with minimal errors and rare outages.

The documentation presented by QlikView is very clear and exact. This makes the process of implementation more easy. If any questions arise while creating the reports it is very easy to access the QlikView documents through the internet. QlikView also has a Qlik Community, full of different questions and answers. This helps a lot to resolve issues even without contacting the support team.

My team attended, but I cannot myself rate, but I think it was good as they've successfully launched a training program at our company themselves for users. It was 3-4 day training.

Training was as expected. The demo environments tend to be more fully featured that our own environment, but the training was clear and well delivered.

It has taken some time to get used to Qlikview and the backend team behind it. From understanding the new regulations on using less images and also pushing for more tools (such as full compatibility on desktop, laptop, ipad, phone). We were given training on this and have helpful tips to find analytics behind Qlikview but it is very much also a learn as you implement system.

Compared to vis.js and d3, Gephi has a much better UI and is easier to use for anyone without a strong code background. vis.js and d3 are more flexible in terms of output and are used by Quaero for more of the ongoing reporting where Gephi is used for exploratory analysis and ad hoc requests. We use all three, just for different purposes.

With QlikView and Qlik Sense the users can answer their own questions more interactively. They also can build their own visualizations without waiting [for] someone from IT to create a new report. The users can navigate through the data finding out relevant information. Through QlikView color code, users can get aware of the relationship between the different data points.

• I have only used the product for education purposes. I will not be the best person to provide details about ROI and business efficiency and customer service. I was personally very excited about the tool and am continuing my work on the tool.

• Speed to market is the really big thing. You can attach to multiple data sources quickly and build a consumable model for a dashboard. It doesn’t require IT talent to build. We have built more dashboards and added more users in the last year, then in our entire history. I was at a company of 30k+ employees before, and we didn't have near this level of BI adoption.
• As a result, we are seeing benefits across business function. For example, within sales, our pipeline has much more visibility. It allows for much faster decisions on things like quotas. One of our biggest power users is in sales ops. She feels her dashboards load 10x faster than our previous tool and she can make changes on the fly.
