Replacement for Time Series Wizard in Oracle BI

Using TODATE and AGO in OBIEE

AGO function provides a shift backwards in Time. So basically, this would help in analyzing monthly sales with last month sales, Quarterly sales with Last Quarter sales etc. Also, Todate and AGO can be used nested within each other.

For this TIP we will be assuming the following hierarchy in the time dimension.
Year --> Quarter --> Month

One of the most important things that one should take care while creating a time dimension is that, the lowest chronological key should be a unique key. And all the above levels should have unique identifiers. For example, if you have columns Year, Quarter and Month, you need to make Quarter and Month unique by appending Year to both Quarter and month.

Now lets look at the syntax of AGO function.
AGO (<measure>, <level>, <shift needed>)
Example:
AGO (BISE1_TUTORIALWH.SALES.AMOUNT,BISE1_TUTORIALWH.TIMESDim.”Month”, 1)

What this would basically do is it would calculate the value of the measure for the previous Month (level of the time dimension shifted by one month).

Similarly, the syntax of TODATE function
TODATE (<measure>, <level>)
Example: (for Year to Date)
TODATE (BISE1_TUTORIALWH.SALES.AMOUNT,BISE1_TUTORIALWH.TIMESDim.”Year”)

What this would basically do is it would summarize the value of the measure from the start of the year till date. Similarly to calculate the Month to Date values use Month level instead of Year.

If you had gone through my blog entry here, i would have talked about using UDML as a way for automating migration from dev to test/prod environments. But the major problem with UDML is that one cannot update the passwords of Connection Pools, Users etc since the UDML expects them to be encoded. In such a case, for updating passwords alone we can use an undocumented command line switch option for the AdminTool. For example, look at the screenshot below.

Inherited Colour Vision Deficiency

Image
Red/green colour blindness is a common hereditary condition which means it is usually passed down from your parents. Colour blindness is usually passed from mother to son on the 23rd chromosome, which is the sex chromosome. Chromosomes are structures which contain genes – these contain the instructions for the development of cells, tissues and organs. If you are colour blind it means the instructions for the development of your cone cells are wrong and the cone cells might be missing, or less sensitive to light or it may be that the pathway from your cone cells to your brain has not developed correctly. The X chromosome is the sex chromosome: males have an X chromosome and a Y chromosome and females have two X chromosomes. For a male to be colour blind the faulty colour blindness gene only has to appear on his X chromosome. For a female to be colour blind it must be present on both of her X chromosomes. This is why red/green colour blindness is far more common in men than women. Bl...
