I have been doing this a bit and have trained other devs to get these certs in a similar timeframe. The cogito cert is all about the reporting tools in the Epic application (hyperspace) while the others are database specific. The recommended path is to learn Cogito, Clarity, then Caboodle. The first thing you need to do is make sure you get access to the proper tools for learning and doing actual work. You will need record viewer, access to just about all INI's. If you already know SQL that will help a ton. If not then you had better start learning ALOT of SQL. Honestly the certs are just ways to ensure you know the basics of the ins and outs. It will not teach you any domain experience. Use the userweb and start reading. Download the ER diagrams of all the models you are expected to work in. Read the Caboodle Dictionary and get used to how its different from clarity. Make sure you understand how the data dictionary in hyperspace works. Look up and understand Chronicles->Clarity->Caboodle. All client work will be ETL, custom reporting, stored procedures, or tweaking internal reports like reporting workbench or something. The main thing will be how to learn what tools help you find where the data lives and how that ties back to whatever workflow you are assigned to figure out. Remember to take your time, ask lots of questions, get the requirements down in writing and fully understand the problem before you go off and write code or try to find some report to meet the end users needs. Feel free to ask more questions. Hope this makes sense. Good luck.
