Description

Introduction

This training provides a comprehensive foundation in kdb+, the high-performance time-series database developed by KX Systems, and its powerful query language q. Widely adopted in industries such as finance, telecommunications, and IoT, kdb+ is designed to process and analyze massive volumes of real-time and historical time-series data with exceptional speed and efficiency.

In this course, participants will gain hands-on experience with kdb+ architecture, q syntax, data modeling, and time-series analytics. By the end of the program, learners will be able to design, query, and manage high-performance time-series databases for enterprise-grade applications.

Prerequisites

1. Basic understanding of databases (tables, columns, queries)
2. Familiarity with SQL concepts (SELECT, WHERE, JOIN, GROUP BY)
3. Basic programming knowledge (any language such as Python, Java, or C++)
4. Understanding of data structures and file systems (recommended but not mandatory)
5. Exposure to time-series data concepts (helpful but not required)
