Data Product
Concept Model: iStandUK General Concepts
A facility that provides controlled access to one or more ATTRIBUTEs.
Notes:
A DATA-PRODUCT will be designed to meet the requirements of a data consumer, and therefore will likely be a transformation from an operational data set, into a smaller set of ATTRIBUTES.
A Data Product may be a traditional database or spreadsheet that is updated periodically; however, a better solution is to provide an API or Data Stream that can be pulled and queried, against a pre-agreed PURPOSE and Terms.
Some partnerships are setting up a ‘Data Mesh’ in which Data Products are ‘nodes’ that are designed for consumers.
A consumer may ‘pull’ from many DATA-PRODUCTs across many Source Organisations. Conversely, a Source Organisation may find that a single DATA-PRODUCT can be re-used to satisfy the requirements of many consumers.

Household
Concept Model: SAVVI Concept Model
A collection of PERSONs who live together at the same RESIDENCE.
Notes:
See definition https://dictionary.cambridge.org/dictionary/english/household
Some use cases may constrain this definition further, such as …
The ONS definition
One person living alone, or a group of people (not necessarily related) living at the same address who share cooking facilities and share a living room, sitting room or dining area.
The Individualised Learner Record definition
A household is defined as a housekeeping unit or, operationally, as a social unit:
- Having common arrangements;
- Sharing household expenses or daily needs;
- In a shared common residence.
A household includes either one person living alone or a group of people, not necessarily related, living at the same address with common housekeeping, i.e. sharing at least one meal per day or sharing a living or sitting room.

Risk Factor
Concept Model: SAVVI Concept Model
A single fact about a Person or Household that can be combined with others to categorise the risk of a VULNERABILITY , and predict NEEDs.
Notes:
Examples of RISK FACTORs include
- Lives Alone
- has a Blue Badge
- has Rent Arrears
- Not Registered with a GP
- No Adult in Household in Employment RISK FACTORs can also be ‘protective’ - that is, information that demonstrates that a risk is reduced, or is already being managed.
A RISK-FACTOR is a type of ATTRIBUTE so that it can be represented as a single fact about a Person or Household; preferably boolean but could have a single value that can be acted on in a Rules Engine.
ATTRIBUTEs support data-minimisation so that only the necessary information is passed, using a precise definition.
ATTRIBUTEs are also useful for other uses such as establishing eligibility for a Service.
