This book covers relational database theory as well as providing a solid introduction to SQL, the international standard for the relational database data manipulation language.
The book begins by reviewing basic concepts of databases and database design, then turns to creating, populating, and retrieving data using SQL. Topics such as the relational data model, normalization, data entities, and Codd's Rules and why they are important are covered clearly and concisely.
In addition, the book looks at the impact of big data on relational databases and the option of using NoSQL databases for that purpose.
