a. Hierarchical model
b. Network model
c. Relational model
d. Object-oriented model

Answer 1

E.F. Codd, who won the Turing Award, created the relational model, where all data is in tuples and relations, and uses declarative operations for queries.

Step-by-step explanation:

The conceptual framework described in the question was made by Codd, who won the Turing Award at age 58 in 1981. This framework is known as the relational model of data management. In the relational model, all data is represented as tuples (which can be thought of as records) grouped into relations (akin to files). Unlike other data models, such as the hierarchical or network models, the relational model uses declarative operations to specify what to get rather than how to get it. This approach allows for greater abstraction and simplicity in database queries and is the foundation of SQL and most modern databases.
