Persoanlized Info Links and Scheduled Updates

 imagine a store manager has access to his or her own store.. and can only view that data

Step 1 -- create a information link that is NOT personalized and gets data for all stores.. so if you open this link it will show everything to everyone, lets say it has a column called as "store number".

Step 2 -- Create an personalized info link that brings back list of stores current user has access too
Generally this is will bring very small number of rows a

Step 3 - In the analysis, add the first information link, Don't worry that at this point it is bringing all data.

Step 3 -- Then do Insert column, select  from Information Link and select the link you created in step 2.

Step 4 -- As part of the insert steps, Match the two tables on the store number column and select the correct kind of join

step 5 -- Now Go to Edit >> Data Table Properties >> Select the table from Info Link created in step 1

Step 6) You should see a tab "schedulde updates" updates tab in that view

" In reload the following data for each user"

you should now see two tables and two checkboxes next to it
Select the checkbox for the table coming from info link 2 (personalized)

and then schedule your analysis

how it works..

when scheduled update runs for first time, first Info link brings data for all stores. and look for the and second link brings list of stores that the system user has access too.

However Spotfire has now cached the data for all stores from the main informaion link 

When a new user opens a scheduled analysis, then the lookup query is run for every user(because you checked that box earlier to force it to run for every user)

Once the loop up table is retreived then the join step is done against the cache in memory and the lookup table

Generally the lookup tables are small and are retreived very fast and join happens in memory..

The big infolink however is not reloaded and hence you save time

This set up gives you personalized data even on scheduled updates

Spotfire Writing back to a database

Lot of time users need to write back to a database.

Spotfire provides different ways to do this, Without going thru the code I am going to talk thru the different options available. But if you need detailed instructions, please leave some comments and will try to provide one

1) Stored Procedures.

Advantages : Complex logic is easy to encapuslate in procedures. Also you are not storing username/passwords anywhere 

Spotfire can execute stored procedures and these procedures could be fetching data, or can be procedures that can be run Pre or Post running a query. You can then use procedures that basically update your database table or even inserts new rows in tables.

When using Spotfire information model it allows you to use these procedures which you can repurpose for updating your database.
Spotfire also understands inputs to a procedure and they can be mapped to your marked rows/filtered rows/ properties/constants etc from your analytics.

Steps to do that would be
1)Create a procedure …

Spotfire Information Link caching & Scheduled updates caching

Spotfire Information Links and the entire Information Modelling layer in Spotfire is a great way to democratize your data.
Information links become great starting point for your users to build their analytics without even knowing SQL or where the server is, what table to use and how are they joined  and all the geeky stuff.  In a typical instance there is a high likelihood that some of the information links are shared between different reports.
With new versions of Spotfire now there is an option available to cache Individual Information links.
The data behind the information link is cached at the Spotfire Server level. The cache is a Spotfire specific binary file which is stored on the Hard Drive of your Spotfire server. So you need to ensure that if you are caching there is enough space. 
The cache itself is self cleaning depending on timeouts and validation query. Also a Spotfire server Restart would clear up the cache, so you need to accommodate for that in your planning.
Caching is ge…

Using Accordions in Spotfire Text Areas

Spotfire 6.0 provides great tools for quickly building your dashboard, but here we will learn to spice up things with the help of new 6.0 text area. If you are not aware the new 6.0 Text area supports HTML, Javascript and CSS.
This opens up possibilities for doing a lot more with the text area.
Some of the basic stuff can be seen here
One of the cool things you can do is build an accordion panel in the text area for better utilization of the valuable screen real estate and helping the overall experience.(Watch the 0:15 second video below to see how accordion works - Sorry for the jitter in the video. The screen recorder does not record fast enough)

Here is the html behind the text area : Please note that Spotfire controls are automatically created when you add text area controls, like filters, drop down lists etc.
