Jan 31, 2019 · A data model is a bunch of tools for describing what our data looks like, the relationship between the data, what the data means, and constraints against our data. There are many examples of data model, including relational model, entity-relationship model, object-based model, semi-structured model, and network model. It can be a natural key, surrogate key, or a composite key. Using our earlier examples, these would be candidate keys for a “customer” table: Social Security Number. Customer ID. First Name, Last Name, Date of Birth. These keys are all candidate keys, as they are an option or candidate to be the primary key.The relational model is one approach for organizing data that has found wide use in database software since it was first devised in the late 1960s, so much so that, as of this writing, four of the top five most popular DBMSs are relational.
