Gephi vs. Oracle Discoverer (discontinued)

It is well suited for projects that are more discovery related. If this is a one-time project that we create a visual for, this would definitely make sense to use. If this is an ongoing analysis (monthly for example), we might look to another software that we would be able to automate a little further in how the visualization comes together

Discoverer is well suited as a reporting tool where data integration doesn't play a major role. Discoverer suits very well situations where a user has to run a query every day. Discoverer reports can be scheduled and the user can just view the data instead of running the query manually. Also, Discoverer takes away the pain of managing the database credentials. Discoverer is not well suited to situations where the whole enterprise wants to view the same dashboard. Discoverer is more of a departmental BI tool. Discoverer doesn't offer many options to integrate data unless one has to create and handle integration using PL/SQL.

• In comparison to other tools such as GraphWiz or Circos, Gephi comes with an intuitive, easy-to-use interface that makes it easy to load your data, and quickly start building all sorts of different graphs. There's absolutely no code that needs to be written for either loading or modeling. And without downloading additional plug-ins, Gephi ships with quite a few standard graph models, as well as some "fun" extras such as the Sierpinski triangle, and a variety of force atlas types.
• Most of the layout types (maybe all) are highly configurable, which can make for extremely customized and unique displays of your data. Again, none of this requires the user to write any code. That said, it is possible to script custom functionality for your models, or even update the Java source code yourself, if you feel like getting technical. Gephi builds are available on GitHub, and the developers encourage people to contribute ideas, improvements, and plug-ins.
• There's a plug-in for Gephi that allows for streaming data to update your model. This essentially allows you to create near realtime graphs of your data in motion. This plug-in was by far the biggest reaston we invested time in the product; to create animated data visualizations without exhaustive hours in development.

• SQL friendly which allows for fast adoption for those users who know how to write in SQL. This makes integration with other programs much easier.
• Accessing data is very fast even with larger data sets.
• The layout is clean and organized similar to a spreadsheet which allows for easier viewing and analyzing of the data.

• I (and many others) have had to expand Gephi's memory manually by experimenting with the configuration file. I'm glad it's possible, but it should be easier.
• Gephi sometimes crashes inexplicably and loses your work, so I have developed a habit of explicitly exporting versions of my graphs as csv's, but I think this should be handled automatically in Gephi.
• Because it is prone to crash, ideally, Gephi would help the user manage his/her use, by estimating processing and memory for very large tasks and prompting the user to confirm their requests before executing. Instead, I just tend to avoid certain functions.

• There is always room for more scalability and optimization of performance.
• Oracle BI changes a lot from version to version. A smoother transition into a new version would be very helpful.
• Oracle BI's reporting tool is a little hard to use at first. The UI/UX of the tool can use improvement.

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

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.

The interactivity in Gephi and the quality of the output figures are impressive. However, the selling point was the fact that we were able to link Gephi into our pipeline using Java's interface. Other products were less customizable and lacking of the sophistication Gephi provided without too much pain during the liking process.

Discoverer was already in place when I joined the company so I was not involved in the selection process. However, I have been involved in the review of Discoverer as compared to alternatives including Business Objects, OBIEE, and SSRS. On a cost benefit analysis Discoverer always came out on top. Changing to another tool never provided enough additional functionality to overcome the cost of conversion and ongoing maintenance.

• 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.

• We have used Discoverer to respond to state sales and use tax audits and saved the company more than the cost of the product. Discoverer has thus assisted in our objective of managing costs.
• Discoverer is used to provide reports for EEOC reporting assisting our goal of complying with all government requirements.
