    <p>I am interested to embed a <a href="http://www.mathworks.fr/products/simulink/" rel="nofollow">MathWorks Simulink</a> like type tool into my application. In this embedded tool units are expressed as blocks with their input and output ports and parameters for each block using my block definition files written in any way that the tool wants. I want the framework to be generic and read the block definitions from somewhere and then allow the user to compose a dataflow of the given blocks based on their definition (preferably comes with graphical editor to do so). I then want the tool to export the user composed dataflow of blocks where I could pragmatically read it in Java (or other languages) and do whatever I need to with it like building an executable version of the given dataflow. </p> <p>I know at advance level, the exported block compositions can be smart enough to be executable but I am ok with exporting the block composition/topology and the input and outputs connected to each other . In other words, I am NOT looking for a dataflow programming language. I am looking for the just the tool-set that allows graphical composition of dataflows and then export the composition as say a json or something that I could load in a programming languages and do whatever with it. </p> <p>The above framework/tool is what Simulink does for blocks coming from its different libraries but I need to embedded such thing in my own tool and was wondering what open source project is close to what I want to do. I guess what I want is a dataflow composition framework. Please correct my view of looking at this.</p>

    1. COI think, there is no standard Dataflow Language exists in the known universe, so there are no editors for it. I've created a *prototype* DF system with a friend of mine, and we are using a simple DF script markup language, which we can display using a small PHP app which translates our DF script to GraphViz script.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
