SUMMARY

The term "database schema" refers to the structural design of a database, encompassing the organization of tables, fields, data types, constraints, and relationships between tables. Key components of a database schema include a list of tables with their respective fields, data types (such as numeric and text), constraints (like uniqueness and range), foreign key references, indexes for efficient data retrieval, and security access details. This definition aligns with standard practices in database management and can be visually represented through various tools, including Elasticsearch indexes.

PREREQUISITES
  • Understanding of database tables and fields
  • Familiarity with data types (numeric, text, etc.)
  • Knowledge of data constraints (uniqueness, range)
  • Basic concepts of foreign keys and indexing
NEXT STEPS
  • Research "MySQL database schema design" for practical applications
  • Explore "PostgreSQL constraints and indexing" to enhance data integrity
  • Learn about "Elasticsearch schema mapping" for search optimization
  • Investigate "SQL stored procedures and user-defined functions" for advanced database functionality
USEFUL FOR

Database designers, software developers, and data analysts seeking to understand the structural components of databases and improve their database management skills.

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

thanks for the quick heads up. i actually got it after asking the question, i was stuck in it like 6 hrs(new level of dumbness achieved lol), then i read the next few lines, it became evident.
