Edgar F. Codd


Edgar F. Codd was not a technology term, but a renowned British computer scientist, best known for his significant contributions to the field of relational database theory. He formulated the 12 principles known as ‘Codd’s 12 rules’ that define what a Relational Database Management System (RDBMS) should adhere to. He was also the inventor of the relational model for database management which revolutionized the way databases function.


The phonetics of the keyword “Edgar F. Codd” would be “Ehd-gahr Ef Kohd”.

Edgar F. Codd is an important figure in the field of technology primarily due to his significant contributions to database theory. He was an English computer scientist who worked for IBM. Best known for inventing the relational model for database management, this was a groundbreaking development when it was introduced in 1970 and still serves as the foundation for many relational database management systems today. These systems include popular software like MySQL, Oracle, and Microsoft SQL Server, showing the extensive influence of his work. Codd’s defining principles for data manipulation, known as “Codd’s 12 Rules,” also remain essential guidelines in designing and assessing database systems. His work revolutionized the way data is stored, retrieved, and organized, making his name synonymous with advancements in database technology.


Edgar F. Codd is not a technology term, but rather the name of a pioneering computer scientist renowned for his significant contributions to database technology. Codd is famously known for developing the ‘Relational Model’ for database management which serves as the theoretical basis for relational databases. Before his model, databases were hierarchical and had a tree structure, but after Codd’s formulation, the idea shifted to a “relational” approach which enabled faster and more flexible information retrieval. The relational model allows databases to be set up and handled using a standard, universal method, irrespective of what is stored in them.Codd’s Relational Model led to the derivation of SQL (Structured Query Language), a standard programming language used in managing and manipulating databases today. His model created languages for data definition, data manipulation, as well as data control. This simplified the process of data management, serving as the foundation for many database solutions that we use in various sectors, including technology, healthcare, finance, and education, to name a few. Hence, the work of Edgar F. Codd has had an immense and enduring impact in the realm of digital data storage and manipulation.


Edgar F. Codd was a British computer scientist who has made significant contributions to the development of relational database theory. Here are three real world examples of his influence:1. SQL Databases: Codd’s theories laid the foundation for the Structured Query Language (SQL), now ubiquitously present in most major databases used in the computing world today, such as PostgreSQL, MySQL, and SQL Server.2. Online Transaction Processing Systems: Formulated based on Codd’s relational database models, Online Transaction Processing (OLTP) Systems like Oracle, DB2, and Informix, are used in many industries, from banking and finance to healthcare and e-commerce. These systems enable a large number of users to manage data and conduct transactions simultaneously.3. Data Warehousing: Solutions like Amazon Redshift, Google BigQuery, or Microsoft Azure SQL Data warehouse are built based on Codd’s principles. These data warehousing solutions allow businesses to sort, analyze, and utilize their data efficiently, supporting decision-making and business intelligence operations.
