Evidence types represent the events and circumstances that need to be captured for case assessment purposes. Examples of evidence types include income, income usage, address, employment, bank details, etc. An evidence record is a set of saved information entered for an evidence type. For example, an employment evidence record may include details about a person's job.
An evidence object is a collection of evidence records showing how a piece of information varies over time. For example, a person's employment evidence has changed twice over the years. This evidence object for employment evidence consists of three records - one record for the initial capture, and one for each change in circumstances.
Each evidence type may have several evidence objects associated with it. For example, if a person has two jobs, two different evidence objects are stored. These objects, plus the records for that evidence object, store all necessary information.
