Question

how is database developed​

Answer 1

Answer:

HEY!!

Explanation:

We can use the waterfall cycle as the basis for a model of database development that incorporates three assumptions:

We can separate the development of a database – that is, specification and creation of a schema to define data in a database – from the user processes that make use of the database.

We can use the three-schema architecture as a basis for distinguishing the activities associated with a schema.

We can represent the constraints to enforce the semantics of the data once within a database, rather than within every user process that uses the data.
