Microsoft offers Visio, a diagramming tool for building flowcharts, diagrams (e.g. network diagrams), org charts and floor plans, available online as a subscription and also in enterprise level packages (e.g. Visio Professional).
SAP PowerDesigner allows our team of data modelers to work and collaborate from a single repository and single data dictionary. This helps enforce consistency as data elements are referenced in other objects. Prior to our use of PD, we might have an element named "ppt" in one table, "participant" in another table and "part" in a third table. By forcing everything to be used from the data dictionary, we avoid these situations because everyone has to go to the dictionary. And we are able to easily do peer reviews on models before they are released because we are collaborating through the use of the repository.
Given the versatility and diversity of the diagrams that can be created with Microsoft Visio, we use this tool for the most diverse activities. With our students, we use it to organize group activities and manage the tasks that everyone has to complete. In research groups, we use it to divide tasks and create organization charts. For research activities, especially the more complex ones carried out, for example, in PhD programmes, the diagrams allow us to display all the work phases graphically.
Visio comes with icons that can help differentiate processes within a map. These can be used to be a legend and helps create a visually appealing flow.
Visio is user-friendly and allows the user to easily navigate through the different creative options that can be used.
Because this is a Microsoft product, Visio works well with other Microsoft products for easy translation.
For me personally I cannot highlight anything specific that has any bearing on how I use the product. Everything is very straightforward and clearly signposted including template desgins and categories. The layout is easy to navigate and as it's part of the MS Office ecosystem means there is less to learn as I'm used to a lot of the cross product functionality.
We use Microsoft Visio to keep our diagrams updated and to that end we will need the subscription to keep using the software. Otherwise we will be left with PDF versions of the diagrams.
Some things that I think should be easy to do are not, at least not for a beginner user. I'm sure it's easy once you get the hang of it but the two main issues I have with Visio are the connecting of different states and searching for graphics/icons after you have chosen a starting template.
We did have to reach out to support to learn how to properly utilize the repository feature and share the data model across many developers. Support was able to help us get this set up correctly. The downside was it took us several weeks before we gave up and contacted support. We should have done that earlier. I would say, however, the documentation wasn't clear on how to do this. So support was a great big help!
Overall, I feel that Microsoft's support is weak. They are now such a behemoth that their model of putting documentation online for their users to sift through is totally outgrown. Given the amount of money you pay for these licenses, Microsoft should provide easy one-on-one support for their products via email or chat. The idea of paying their rates for support incidents is ridiculous. If you have an enormous amount of time on your hands, use their support websites and you will eventually find a solution most of the time.
Oracle SQL Developer Data Modeler : Unfortunately this tool only supports Oracle Databases as a target database, but has many features similar to SAP Sybase PowerDesigner. erwin Data Modeler: Has some issues when switching from Conceptual Model to Physical Model, Impact Analysis, and formatting copy and pasting. Vertabelo: Only supports online models and from a governance perspective, it is impossible for me to connect my target database with an online application because of company policy and regulation requirements.
Even though it’s a more expensive solution, Vizio is built for the enterprise. Therefore, it integrates perfectly with our existing Microsoft stack, and quite frankly, because it’s such a more mature product, it provides exactly the functionality we need and expect.
Visio diagrams have help us streamline processes that reduce costs and improve efficiencies.
It is a very complete program, it allows you to make industrial and civil works diagrams. It also allows you to design 3D graphics. It is a very reliable program.
Its ability to work with vectors is a big plus. It can easily import SVG graphics, edit their individual lines and then being able to export the edited SVG again.
