Hello guys, how are you?

Is there any way to reverse engineer a PL/SQL code? In order to look at the modelation of the code and/or dependencies between packages/procedures and tables or something like that?

Thank you!

Hello,

MoDisco official release is currently not containing a PL/SQL model discoverer.
However, there have already been different prototypes of such components based on MoDisco.

For instance, in the context of the ongoing ARTIST collaborative project , a partial SQL model discoverer has been initiated (covering INSERT statements so far).
Also, some years ago, a relational database information discoverer has been prototyped in the context of MoDisco. Some of its elements (e.g. used metamodels) could be of interest for you.

In this context, is there a way to build a PL/SQL discovery model on top of MoDisco/Eclipse? My company desires to have a high level model (UML/Architecture Diagrams ...) of the system that is written in PL/SQL and in a future a possible migration to Java.

Thanks again!

You can develop your new PL/SQL discovery component using any Eclipse-based technology you want, and then package it as a MoDisco model discoverer following the provided instructions and API (cf. MoDisco documentation, section "MoDisco User Guide -> Infrastructure -> Discovery Manager -> Developer Documentation").
For implementing the parsing part, I would recommend you to take a look to technologies such as Xtext for instance.

Thanks for the info!

One last question if Imay..

I saw this example (MoDisco-Demo_September2011) and basically it is demonstrating MoDisco -> Java Model Discovery -> Some transformations (refactoring) and metrics!

There is some example of a fully language change like java -> C++/C# or something like that?

Thanks!

We currently don't have such an example developed in the context of the MoDisco project.
But we would be grateful if you could point us to some scenarios of this kind Smile

Is the Model Discovery Java Open Source? Can I use it as a base project to build my own PL / SQL Model Discovery?
I'm having a little trouble understanding how it all works, for example: how would I use the Xtext as part of the process. Confused

Of course, all the MoDisco project is completely open source. You can get the sources from the installed MoDisco SDK or directly from the MoDisco project Git repository.

For using Xtext as part of your component, and in addition to all the official Xtext resources, I would recommend you to take a look to the source code of the SQL Model Discoverer developed in the ARTIST EU project (as also using Xtext and then packaged as a MoDisco discoverer) .

So...is it just me that finds the documentation for installing the SQL Model discovery impenetrable? Wink

I mean past the point of installing MoDisco which is of course completely straightforward. Is this a plugin or what? How do we actually make use of it?

thanks,

Miles

Hello Miles,
You're right that the installation of this feature is (much) less straightforward that the MoDisco integrated ones.
If this component is finally integrated in the released version of MoDisco in the future, it should be much better Smile

In the meantime, you can find binaries of the corresponding 4 plugins from here, or you can rebuild them from the sources using the link provided in previous post (supposing that you have MoDisco and Xtext already installed).
These plugins can then be installed as any regular deployable plugins.
For running the actual components in your workbench, you can right-click on the input (e.g. SQL source file) and then go the MoDisco "Discovery" menu and select the proper contextual action.
I hope this helps.
