Overview of this book

Moodle is the de facto standard for open source learning platforms. However, setting up and managing a learning environment can be a complex task since it covers a wide range of technical, organizational, and pedagogical topics. This ranges from basic user and course management, to configuring plugins and design elements, all the way to system settings, performance optimization, events frameworks, and so on. This book concentrates on basic tasks such as how to set up and configure Moodle and how to perform day-to-day administration activities, and progresses on to more advanced topics that show you how to customize and extend Moodle, manage courses, cohorts, and users, and how to work with roles and capabilities. You’ll learn to configure Moodle plugins and ensure your VLE conforms to pedagogical and technical requirements in your organization. You’ll then learn how to integrate the VLE via web services and network it with other sites, including Mahara, and extend your system via plugins and LTI. By the end of this book, you will be able to set up an efficient, fully fledged, and secure Moodle system.

Moodle contains a powerful caching framework called Moodle Universal Cache (MUC), which allows certain functions to take advantage of different configured caching services (https://docs.moodle.org/en/Caching). A typical example of a function that makes use of caching is string fetching, especially when multiple languages are supported.

The MUC background

Before we take a look at how MUC works, let's explore some basic concepts first, namely cache types (modes), cache stores, and cache definitions.

Cache types

There are three different cache types in Moodle, often referred to as cache modes:

  • Application cache: The application cache deals with operations that are Moodle-specific, for example...
