Agreed! I'm very excited to start using BIML. One of the complaints I've always had about BI (SSRS/SSIS, etc...) is that beyond the SQL code, it's seemed like it was basically presumed that I would rather use a GUI than code things myself, when in fact, for me it's precisely the opposite. I hate GUIs (and the nasty, unmanageable code they tend to generate). I like to have complete control of the code in my projects, and be able to account for every keystroke, what it does, and why it's there. NO GARBAGE CODE PLEASE! :-D
Whenever I inherit code from other developers in my company and it's a sloppy, unreadable mess, I just shake my head and weep for the future of software development... and then I clean up the mess :-P I feel like I'm the only one who cares about clean code (and it's reusability)! So frustrating... I would much rather code my own Reports/SSIS packages, etc... but the XML code generated and used in these RDL/DTSX files is not meant for use in day-to-day coding (all the GUIDs, etc...). However, I have edited the code manually for existing RDL files just avoid openning the GUI and dealing with the overhead there when I just need to make a few minor tweaks ;-)
BIML on the other hand seems like it's going to be a real programming language akin to HTML, etc... A precisely controllable, precisely reproducible and therefore reusable, programming language that is reasonably readable and more importantly writable by people who know how to read/write programming languages.
I hope this just continues to grow in popularity, and eventually, instead of having to compile the BIML code to generate the DTSX, SQL Server will just be able to execute BIML code
Also, I'd like to see BIML (or some other mark-up language, but why not just extend BIML since it's all BI) generating RDL files as well for the front-end element of BI. If this already exists, and I'm just clueless, feel free to gimme a clue
This was my first time hearing about BIML, so it wouldn't suprise me if there's more new goodies for me to learn about.
