OBIEE How to get started

About two to four times a week I get an email or an OTN request from people who want to get started as an OBIEE consultant. In this “sticky” article I want to give you some basic starting points.
Get familiar with the basic terminology:
Before you start with anything get up to speed with dimensional modelling.

(Get familiar with the works of Ralph Kimball)
Brush up your modelling capabilities, ADAPT is a good method to start with:
Read up on your Data Warehouse /  BI basics:
Get a clean (virtual) machine and first install an Oracle database. The 10g express version is OK for starters.
Maybe you want to brush up your DB skills:
Next get the latest version of OBIEE
Download the documentation:
If you have everything installed work trough the OBE tutorials on OBIEE.
Don’t not only copy the click but be sure you understand what is happening!
Download and install the extended sales sample RPD and CAT. Dissect every report and dashboard to understand how the reports work.
Have a good look around at the OTN forums. Most questions have been asked before.
Read the works of Stephen Few on how to design a good dashboard from the visual standpoint:
Learn to create reports and dashboard which people need, which is often completely different of the reports and dashboard they intentionally asked for…
If your start an 11g project brush-up your weblogic skills:
Configure your OTN account so that you “watch” certain users. Looking around at the forum you soon learn which users give the most valuable answers.
Start following the OBIEE related blogs. At this moment there are about 10 your really need to watch. (Check my blog list).
Must read material:

If you need more practices check out the Oracle Learning Library:

    great post John.
    Do you know who moderates the OTN OBIEE forum? It would be great to get this made as a sticky on there.

    Just a note on your very useful note: the 2nd link regarding dimensional modeling is defunct!

    Hi,

    I have a strong Finance & Accounting background - but I have implemented Cognos Planning budgeting and forecasting software - have some elementary knowledge. I also have implemented Crystal Xcelsius dasboards at number pf paces.Would it a good idea for me to learn OBIEE reporting and dasboarding?

    Thanks,
    AS

    @barun,

    It's always good to learn something new, but the basics,(dimensional modeling) is much more important then the tool!

    Regards

    Hi! Would you know how to setup a measure that would get the previous year data?
    Let's say I have Current year data 2009, how will I build the formula for the column that would generate the Previous Year data?
    In my Date dimension table, I have Current Year and Previous Year columns.

    Also, how will I setup the formula to get the percentage change of this 2 fields?

    Thanks!

    @Katherine,

    Simple make an alias of your fact table shifted one year back.

    regards

    Hello Sir:

    I had a problem with our OBIEE Analytics, when I run it in our Development Environment, I could see the data results. But when in Production, i get the message "NO DATA
    Your selection didn't result any data. KINDLY TRY AGAIN !!!"

    What seems to be the problem, I am just new to this OBIEE and there was no knowledge transfer.

    Thanks...

    John Minkjan said...

    @arze arce,

    Did you change the connection pool? Does the view data in the physical layer give you the required results?

    Regards John

    Great post, John...especially for a novice like me.
    I have attended a training course in
    OBIEE and familiarized myself with the tool.
    I am planning to search for a job in OBIEE and got to know that it is not possible to get a break as a fresher. Min 5 yrs experience is required....
    Can you let me know your thoughts regarding my job search in OBIEE as a fresher? Or, your guidance in my going further with OBIEE?

    Thanks a lot.
