My instinct is to leave GraphViz and PlantUML to do as much as possible by default. However, be assured that diagrams can be altered to suit your requirements: Related objects can be placed side by side, or vertically, You can use dotted arrows or arrows with a different head You can opt to avoid shadows, and change the colour of anything. It is so good that IвЂ™m not going to attempt to repeat anything from it.

Fortunately, PlantUML has an excellent PDF manual which explains that you can change almost everything. I have taken quite a few design decisions which you may not like.

IвЂ™ve given the SQL code at the end of the article. The PlantUML source code that we used is this, generated from SQL codeвЂ¦

Here we want to keep things simpler, and just want to document tables, views, and functions and their dependencies in detail. If you want to do this, IвЂ™d advise you just to open the wallet a bit and use SQL Dependency Tracker instead. PlantUML is able to give you immense diagrams which are probably useless for our purpose here. We have drilled in to the detail from the first diagram here to look more closely at the tables. As I have no strong feelings about the way that a table is represented, IвЂ™ve not deviated much from the standard class. Now UML never had a stereotype to deal with a relational database, but there is an established database profile that includes a logical and physical model. Sometimes we would like to do a bit more than this. You just execute the code, save the result to disk, and pass the result to PlantUML, which has a command-line interface.

Once youвЂ™ve got some confidence, you can use PowerShell to update diagrams automatically. This type of diagram was never intended to provide an entire map of your database. Any network diagram quickly morphs into a birds-nest diagram if you try to do too much. Be wary about including too much in a diagram. Obviously, there is plenty more you can include but there is something to be said for having just one clear message to every diagram. вЂ¦but you can of course use it with any other database object such as dbo.ufnGetContactInformation. вЂ¦and copied the result from the results pane (use text mode and set the вЂ QueryвЂ вЂ OptionsвЂ -> вЂResultsвЂ™ -> вЂTextвЂ™ -> вЂMaximum number of characters displayed in each columnвЂ to 8192 or some other generous figure) All I did to do this was to use the text: Note that schemas have been represented as folders. IвЂ™ve always been caught out by views so it would be nice to see those objects in the database that a view references. LetвЂ™s look at AdventureWorks, just so we can try things out. Data Modelling With Unified Modelling Language (UML) WeвЂ™ll just stick to showing a subset of your database objects and the dependencies between them.

PlantUML uses simple text-based instructions to render UML diagrams and these can be generated from SQL to show you such things as the intricacies of your database permission system, the foreign-key dependencies, or the details of your indexing strategy for a table. You can use your favourite editor via a command-line interface as well. I use AsciiDocFx, which installs the prerequisites for you (though you may need to set the path to your GraphViz install.

If you want to use PlantUML from the command-line, there are install instructions here. If you use DocuWiki for documentation, there is an add-in for PlantUML, which is handy for teams since there is nothing to install on your machine then. There are several Atom packages that add PlantUML integration. Chrome has an Add-in that runs PlantUML called the UML Diagram Editor. With that, and the PlantUML manual, you should be well away with using this interesting application. To get you started, there is a little browser application here on the PlantUML site that allows you to type in PlantUML code and view the results. I will use TSQL code to create the PlantUML code directly. In this article IвЂ™m going to show how it can be used to easily generate class diagrams for database objects. For a relational database person who winces at the terms вЂclassвЂ™ and вЂpersistenceвЂ™, even UML modelling has its uses as a way of communicating ideas and designs. Automatically Creating UML Database Diagrams for SQL Server - Simple Talk Skip to contentДЄlthough you may have little urge to use UML diagrams in your everyday work, PlantUML is versatile enough to provide for a range of requirements.
