Kdb+/q

Kdb+/q can be downloaded from https://kx.com/developers/download-licenses/.

In particular, there are two free versions of kdb+/q: the 32 Bit Personal Edition and the 64 Bit Personal Edition (On-Demand).

Both editions are licensed for personal use.

The 32 Bit Personal Edition:

• is permitted to run on-premises;
• is permitted to run on cloud;
• provides access to KX Fusion interfaces and integrations;
• provides access to community support;
• Linux/Mac/Windows/Raspberry pi versions are available.

The main limitation of the 32 Bit Personal Edition and, more generally, of any 32-bit program, is that it can only ever use up to 4 GB of memory. That's due to the 32-bit address space, since 2^32 = 4,294,967,296 bytes. For some use cases this may be a serious limitation.

The 64 Bit Personal Edition (On-Demand):

• requires "always on" internet connection;
• is permitted to run on-premises;
• is compatible with KX Developer and KX Dashboards Direct;
• provides access to KX Fusion interfaces and integrations;
• provides access to community support;
• gives regular access to upgrades;
• Linux/Mac/Windows versions are available.

The 32 Bit Personal Edition can be downloaded immediately, whereas for the 64 Bit Personal Edition (On-Demand) you would need to request a license. Both editions are available via https://kx.com/developers/download-licenses/.

Integrated development environments (IDEs)

There is no one-size-fits-all IDE for kdb+/q. Therefore we recommend that the reader download some/all of the tools listed above and give them a try.

Q Insight Pad (Windows-only)

Q Insight Pad (sometimes referred to simply as qPad) by Oleg G. Zakharov is a kdb+ client, written in C++ to run under Windows; as a result, it is fast, memory-efficient and easy to use. The author makes a special emphasis on providing a Windows-style GUI that is visual, simple and intuitive.

Q Insight Pad provides simple but useful visualization capabilities.

An unregistered but fully functional version (working with free versions of q) can be downloaded for free from http://www.qinsightpad.com/.

This version expires every 3 months. If you want to license Q Insight Pad for use in your organization, contact the author: http://www.qinsightpad.com/contact.html.
