Which of the following is objective database and not a relational database?
Chọn đáp án đúng:
- Web SQL Database

Solution
To determine which of the options is an objective database and not a relational database, let's analyze each option:
-
Web SQL Database: This is a relational database that allows for SQL queries on client-side browser storage.
-
FileSystem API: This is primarily an API for reading and writing files on the client side and does not function as a database.
-
IndexedDB: This is an object-oriented database that allows for the storage of objects (including files) and is not based on relational data.
-
User Data: This generally refers to any personal data stored by the user, which doesn't specify a database type.
Conclusion
The answer is IndexedDB, as it is the only option listed that is an object-oriented database and not a relational database.
