System overview

An OS2Datascanner installation consists of three components: the administration interface (a Django app), the scanner engine (a set of system services), and the report interface (another Django app).

The administration interface is used to build up scanner jobs: sources of scannable things and rules to search for in them. The details of these jobs are stored in a PostgreSQL database. It's intended for use by an organisation's administrators or data protection officers.

The scanner engine, also known as the pipeline, consists of five stages built around RabbitMQ message queues. Each of these stages is a program that reads a message, carries out a small, simple job, and then sends one or more messages to another stage. At a high level, the scanner engine receives scan requests from the administration interface and produces scan results.

The report interface displays the results of the scanner engine. It shows matched objects and details of why they were matched, and allows users to flag certain results as irrelevant. It's intended for use by all of an organisation's employees.
