    Course overview

    Fundamentally, a database management system is a computerized data storage system. Clients are provided with the ability to carry out a variety of actions on such a platform either for managing the database structure or manipulating the data in the database. Vignesh Sekar, a software engineer, and computer science instructor, developed the Database Management System from scratch - Part 1 online certification, which is offered through Udemy.

    Database Management System from scratch - Part 1 online course involves 12 hours of extensive lectures along with 2 articles to offer students a thorough understanding of database management systems from the ground up. Database Management System from scratch - Part 1 online classes teaches about the topics like ER model, relational model, closure operation, functional dependencies, and equivalence checking. By the end of this course, students will be prepared to respond to any question about database management systems in tests like the GATE, ISRO, and PGEE.
