What are the reasons for converting SQL queries into relational algebra queries?

Converting SQL queries into relational algebra queries can enhance understanding of the underlying operations and data manipulation processes. It provides a more abstract representation of query execution, helping to optimize performance by identifying potential inefficiencies in the SQL statement. Additionally, relational algebra serves as a foundational theoretical framework for database theory, aiding in the formal analysis and optimization of database queries. Finally, it facilitates the translation of queries across different database systems by providing a common operational language.
