All of the options mentioned define the structure of a database. Here's how:

1. Tables: A database is structured into tables. Each table holds information about a different aspect. For example, a university database may have separate tables for students, courses, and professors.

2. Attributes: These are the properties or characteristics of the records that help to define the nature of the data in a database. For example, in a table for students, the attributes could be student ID, name, major, etc.

3. Records: These are the rows in the table, each of which contains information about a specific instance or object in the table. For example, a record in the students table could contain the information for one particular student.

4. Keys: These are special attributes used to relate tables in a database. They ensure each record within a table can be uniquely identified and help establish relationships between the tables. For example, student ID could be a key in the students table.

So, all of these elements - tables, attributes, records, and keys - work together to define the structure of a database.
