dataobjectinstantie

In data modeling, dataobjectinstantie refers to a concrete occurrence of a data object type. It is the actual data record that fills the structure defined by the dataobjecttype and represents one real-world item or event. The type specifies the attributes, data types and constraints, while the instance holds the specific values.

An instance is identified by a unique key; attribute values capture the state at a point in time. Instances can be created, modified or deleted, and may link to other instances via identifiers or references. This linkage enables relationships such as one-to-many or many-to-many between different data objects.

Example: if the dataobjecttype is Customer with attributes such as customerId, name, email, and address, a dataobjectinstantie would be a specific record like customerId=123, name="Ada Lovelace", email="[email protected]", address="1 Computing Lane".

Lifecycle and governance considerations accompany the management of dataobjectinstantie. Instances are stored, persisted, and subject to data quality checks, privacy rules, retention policies, and access controls. Audit trails may document creation, modification and deletion events, supporting data provenance and compliance requirements.

Relation to broader data architecture: dataobjectinstantie is the concrete data that applications query, report on and analyze. It interacts with dataobjecttypes (schemas or classes), storage mechanisms (databases, data stores, or object models) and metadata about lineage, ownership and quality. In practice, the term is used to emphasize the distinction between the abstract definition of a data object and its actual manifestations.
