Intermediate-level algorithm

Intermediate-level database operations in SQLite include complex queries, joins, subqueries, and transactions. These skills are important for efficiently retrieving, updating, and manipulating data in a database. By mastering these operations, developers can optimize the performance of their applications, ensure data integrity, and create more complex and powerful functionalities. Understanding how to use joins and subqueries allows for retrieving data from multiple tables and applying filters, while transactions ensure that database operations are atomic and consistent. Overall, these skills are essential for building robust and scalable database applications.
