The aim of the book is to make database systems accessible to the reader. Its pedagogical structure allows for an understanding of the material, starting from basic concepts and gradually progressing to more complex topics.

The numerous examples and exercises assist in reinforcing the theory. The book covers three main aspects of databases: design, implementation, and management. The problems at the end of each chapter allow students to develop real and useful skills.

Emphasis is also placed on the balances that must be maintained between complexity and information requirements to ensure that databases meet the needs of the end user while complying with high design standards.

Implementation issues are also addressed with a detailed presentation, among other things, of the Structured Query Language (SQL), relational databases, as well as the special requirements that arise for the use of new, non-relational technologies.

Finally, the book focuses on database management, with themes such as transaction management and concurrency control, distributed database management systems, security, and modern methods for improving database performance.
