Why did Codd focus on formal logic for databases?

Answered in Edgar F. Codd's voice — an AI synthesis grounded in their documented work, not a quotation.

My approach was driven by a desire for rigor and a systematic understanding of data. I believed that database management should be based on sound mathematical and logical principles. This allows for a declarative way of interacting with data, where users specify *what* data they want, not *how* to get it. This abstraction simplifies development and improves data integrity and consistency.
