Hi,

" .............

In-memory analytics is an approach to querying data when it resides in a computer’s random access memory (RAM), as opposed to querying data that is stored on physical disks. This results in vastly shortened query response times, allowing business intelligence (BI) and analytic applications to support faster business decisions.

As the cost of RAM declines, in-memory analytics is becoming feasible for many businesses. BI and analytic applications have long supported caching data in RAM, but older 32-bit operating systems provided only 4 GB of addressable memory. Newer 64-bit operating systems, with up to 1 terabyte (TB) addressable memory (and perhaps more in the future), have made it possible to cache large volumes of data -- potentially an entire data warehouse or data mart -- in a computer’s RAM.

a lot of other tools are in memory,

In-memory is nothing but your RAM.if you are asking in terms of In-memory analytics, then to retrieve data stored in RAM is the In-memory technique.which is faster to access your data.

there are many in-memory tools in market like Qlikview,Tableau and all..

Let's say the giant is Qlikview in this technique...:)

Please refer reference material for detail basic..

Hi,

When you are accessing Dashboard using AccessPoint or Desktop the entire dashboard data is stored in RAM and then when you change any selections it generates the charts using data in RAM instead of fetching from File System or database. So, that is why you are getting faster results.

Ca pls get me clarfied like every Dash board data will be load into Ram whwn the time of accesses.

compare with other BI tools(Not in memory tools) here how they differ from Qlikview here using ram.

Hi,

Yes Mahesh, every dashboard that you are accessing is stored in RAM and performs operations in RAM directly. In other reporting tools like BO everytime it queries to database and generates reports.
