What is a .QVD file?
A .QVD file is a type of database file that is specifically used by a program called QlikView. QlikView is a tool designed for business intelligence, which means it helps businesses understand their data better, such as sales, revenue, costs, and profits. The .QVD file stores data in a special way that makes it very fast for QlikView to use. When the data from a .QVD file is needed, QlikView doesn't read it from the hard drive like most programs do. Instead, it keeps the data in the computer's memory (RAM), which is much faster. This is like keeping your tools on a workbench instead of putting them back in the toolbox every time you use them. Because of this, when you open a .QVD file in QlikView, it can quickly access and analyze the data for reports or to help make business decisions.
The .QVD file is an "uncompressed RAM image," which means it is a direct copy of what was in the computer's memory when the data was last used in QlikView. This helps the program to open and load the data very quickly because it's already in the format that the computer's memory uses.
To open a .QVD file, you need to use the QlikView program by QlikTech International. However, it's important to note that this program has been discontinued, which means it's no longer being updated or officially supported. Despite this, if you already have QlikView, you can still use it to open and work with .QVD files.
.QVD files are important for businesses that use QlikView for analyzing their data. This could include looking at past performance, understanding current trends, or making predictions about future activities. The fast access to data provided by .QVD files helps make these analyses quicker and more efficient, which is valuable for making informed business decisions.
