Hi,

Qikview is in-memory analysis tool means all analysis done in the System RAM when accessing the QVW and the calculation and other manipulation is also done there. But the data is loaded in the QVW file but when accessing this QVW the data loaded into the RAM for analysis and it give result from there.

Find some attached documents

Hi,

that's easy: The concept is that everything - the complete code of the software as well as the working_data - is

helf in working_memory. That means that no access to the harddrive is necessary for the execution of the program, which in turn makes the thing run a lot faster than is access to the harddrive were necessary.

You can find a detailed explanation of how it works on Wikipedia.

SAP has the same technology with HANA and I guess other tech_companies have it too in the meantime.

In our times where memory is quite cheap, that is a very attractive concept for many software products.
