An organized collection of data which is usually stored and accessed electronically using a computer system is known as a database. Complex databases are generally developed through formal design and modeling techniques. The software which interacts with the database, end users and applications is called database management system or DBMS. The main purpose of DBMS is to capture and analyze data. A few different types of databases are in-memory database, cloud database, distributed database and embedded database. A database management system allows the user to view the database on three different levels- external level, conceptual level and internal level. This book discusses the fundamentals related to the development and management of databases. Some of the diverse topics covered herein address the varied branches that fall under this category. This book will prove to be immensely beneficial to students and researchers in this field.
