Hi,

Answer is your question

In Memory

When Application load in Access point the whole application with data is loaded in Memory and keep in memory till you clear your Qlikview Server memory.

Hi Hari,

When you are accessing Dashboard using Access Point 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.

traditional bi tools like cognos or BO fetches the data from disks but qlikview opposes that is the why performance is increased. Hope it will helpful!!

Analyze Big Data with QlikView’s 100% In-Memory Architecture

QlikView’s patented in-memory data engine compresses typical data by a factor of 10, meaning a single 256GB RAM server can load upwards of 2TB of uncompressed data. This represents billions of rows while offering response rates only possible with in-memory architectures. Other QlikView features such as document chaining and binary load further accelerate the exploration of very large data sets. This is the path chosen by many Qlik customers to analyze terabytes of data stored in data warehouses or Hadoop clusters and similar repositories.

Hi,

Data is held in MEMORY on the SERVER, not on the local machine.
