Across

1. The process of organizing data in a database to eliminate redundancy and improve efficiency.

2. The process of transferring data from one database system or storage system to another.

3. A type of database that provides a non-relational data model, flexible schema, and horizontal scalability, often used for big data and real-time applications.

4. The process of determining the order in which transactions should be executed in a database system.

5. A concurrency control protocol where a transaction acquires all its required locks before starting execution and releases them all at the end. It enforces serializability.

6. A SQL statement that uses parameters to substitute variable values in the query.

7. Security vulnerabilities that occur when user input is directly concatenated into SQL queries.

8. A type of database that organizes data into tables with rows and columns, and establishes relationships between tables.

9. The process of retrieving or restoring data that has been lost, damaged, or accidentally deleted from a database, usually through the use of backup copies.

10. The understanding or awareness acquired through the interpretation and application of information.

Down

11. The property that ensures the database remains in a valid state after a transaction.

12. The property that ensures transactions are executed in a way that they are unaware of each other.

13. The process of undoing all changes made within a transaction and returning the database to its previous state.

14. A concurrency control technique in database systems where transactions are ordered based on their timestamp values.

15. The property that ensures that committed transactions survive permanent system failures.

16. The storage of the same data in multiple places within a database, which can lead to inconsistency and inefficiency.
