b. low cost.
c. ease of implementation.
d. efficiency

Answer 1

The advantages of relational data models include reduced information redundancy, easy interpretation and communication, and efficiency.

Step-by-step explanation:

The advantages of relational data models generally include:

1. Reduced information redundancy: In a relational data model, data is organized in tables, and each piece of data is stored only once. This reduces redundancy, as data does not need to be repeated across multiple tables.
2. Easy to interpret and communicate: Relational data models use a tabular structure that is easy to understand by both humans and computers. This makes it easier to interpret and communicate the data.
3. Efficiency: Relational databases are highly optimized for querying and retrieving data. They use indexing and other techniques to quickly locate and retrieve the required information, making them efficient for data management.
