In summary: Based on this information, I would say that the table is likely a student table, and the columns correspond to name, roll, and grades. The salary column might indicate the teacher's salary, and the experience column might indicate how long they've been teaching. The subject fields that the teacher teaches might be indicated in the last two columns.

What I guess (based on experience) is it's asking about this.

Table student-:
Name
Roll
Grades

Table Teacher-:
Salary
Experience
Subjects Taught

This is database schema according to my guess. Is this the context used here?
A rather loose definition could be a "schematic of database". Would it be appropriate here?

yes and yes. If you do a google search of "database schema" and clik on images. This will become very clear.
Database schemas will contain:
-list of tables, and what fields they contain
-list of fields, and what kind of data they contain. (numeric, text, etc..)
-constraints on the data (uniqueness, range, list of values to select from)
-fields that are a reference to a record of another table.
-indexes to make looking up data easier.
-security access and user information
-often a way to add code to a database (user defined functions, stored procedures).

and you should be able to find that in an elasticsearch index in some form

1. What is a database schema?

A database schema is a visual representation of the organization and structure of a database. It outlines the tables, columns, relationships, and constraints within a database.

2. How is a database schema used?

A database schema is used to define and organize the data in a database. It serves as a blueprint for creating and managing the database, and ensures consistency and accuracy of the data.

3. What is the importance of a database schema?

A database schema is important because it helps to maintain data integrity, facilitates data manipulation, and allows for efficient data retrieval. It also helps to ensure that the database is easily understood and maintained by multiple users.

4. How does a database schema differ from a database model?

A database schema is a specific implementation of a database model. A database model is a conceptual representation of a database, while a database schema is a physical representation of that model.

5. Can a database schema change over time?

Yes, a database schema can change over time as the needs and requirements of the database evolve. Changes to the schema can be made through database design and management tools.
