The SQL query for the Terra database will depend on the specific task or information you are trying to retrieve. However, a basic SQL query to retrieve all data from a table in the Terra database would look like this: ```sql SELECT * FROM table_name; ``` Replace "table_name" with the actual name of the table you want to retrieve data from. If you want to retrieve specific columns or apply filters, you can modify the query accordingly using the SELECT and WHERE clauses. **

The SQL query for a SQLite database is similar to other SQL databases.

Database normalization is the process of organizing data in a database in a way that reduces redundancy and dependency. It involves breaking down a database into smaller, more manageable tables and defining relationships between them. The goal of normalization is to minimize data redundancy, improve data integrity, and make the database more efficient. There are different levels of normalization, known as normal forms, with each level addressing specific issues related to data organization. **
