9 Questions
What is the main purpose of the Source Identifier in the Non-integrated model?
Separating business keys by 'source'
Why is the Non-integrated model considered 'not integrated at all'?
It guarantees validity despite not being integrated
What is the significance of the Source of business keys in the context of the Non-integrated model?
It highlights the uniqueness of business keys within each source table
True or false: The Non-integrated model separates business keys by 'source' and ensures the validity of the model by guaranteeing that the source is the source table
True
True or false: The Non-integrated model is a counter-measure for 'overintegrated' models and is not integrated at all, but is guaranteed to be valid
True
True or false: In the context of the Non-integrated model, if multiple tables for customers exist in a data source with overlapping business keys, the source must be the source table to guarantee a valid model
True
Match the following terms with their definitions:
Source Identifier = Identifies the source table in the Non-integrated model Non-integrated model = Counter-measure for 'overintegrated' models and separates business keys by 'source' Overlapping business keys = Occurs when multiple tables for customers exist in a data source with shared business keys Source Vault = Not a Source Vault according to the text
Match the following terms with their meanings:
Counter-measure for 'overintegrated' models = Non-integrated model Valid model guarantee = Characteristic of the Non-integrated model Business key separation = Function of the Non-integrated model Source table guarantee = Ensures the validity of the model in the Non-integrated model
Match the following phrases with their correct descriptions:
Not just the data source = Source of business keys in the Non-integrated model Multiple tables for customers with overlapping business keys = Scenario where the source must be the source table in the Non-integrated model Integrated at all = Characteristic of the Non-integrated model Guaranteed validity = Feature of the Non-integrated model
