Hi there.
I'm looking for some guidance on CASE tools and whether my concerns are valid.
Recently I was in a meeting between my employer and an external software company which have a CASE tool currently in beta. They demonstrated this tool to us, showing how you build a UML model in Enterprise Architect (or something like it) and then, through their tool, that UML model is transformed into a Visual Studio project, with C# files, stored procedures for SQL Server, code for the data layer, WCF stuff, logging code and allsorts.
Now, admittedly, I don't see the point in this, as in I'm not convinced it will save that much time (plus it feels like overkill). The tool authors said that a trial of the tool at another company had saved a team there 5 weeks of development time (from 6 weeks down to about 1 week) using this tool. I find the accuracy of that estimate hard to believe.
My main concern is whether using this tool is going slow down my productivity. For example - Say I have a UML model which I built a VS solution from. Now, I want to rename a class method to something else; will this mean having to update the UML model first and then rebuilding the code? Is this how case tools normally work?
Something I will need to check with the authors is the structure of the generated VS solution. I like the Domain Driven Design way of project structure - Infrstructure, Services, Model, etc. I doubt very much this tool will do that.
Also, I've been playing around with Entity Framework Code First and think it's a great way to build the data model. I have nice repositories, unit of work classes and other design patterns that work well with EF. I have data anootations and stuff like that working great. By not having EF (the CASE tool uses it's own data layer code) I'm concerned that this tool's data layer code might not be a nice to integrate in the UoW pattern, repositories, etc. This I will need to verify when I get a closer look at the generated code.
What are other people's experiences with CASE tools? Am I being paranoid about nothing? Am I being unfair - are my negativities unfounded?
EDIT:
I like to use TDD/BDD for building my code, and using a CASE tool looks like it will make this difficult. Again, any feedback on this would be great.
Cheers.
Jas.
