Step-by-step explanation:
A schema is an overall logical view of the relationships among data elements in a database. So the correct answer to the question is a) Schema. A schema defines how the database is structured and organized, including the tables, fields, and relationships between the tables.
Databases are used in many applications ranging from websites, banking systems, to content management systems, and understanding a schema is fundamental for querying the database, designing it, or making changes to its structure. Queries, which are requests for data retrieval from a database, rely on the schema to determine how to fetch the information. Indexes are used to speed up search queries on a database, and a record is a single entry in a database table.
