In this course, you will be introduced to databases and explore the modern ways in which they are used. Learn to distinguish between different types of database management systems then practice basic creation and data selection with the use of Structured Query Language (SQL) commands.
Databases work by organizing and storing information in a structured or unstructured format, allowing easy access, retrieval, and modification. At the core of every databasesystem is the Database Management System (DBMS)—a software layer that acts as an intermediary between users and the raw data.
We explore main DBMS types, their features and applications, help choose optimal solutions, and discuss professional development paths in this field. This guide is valuable for both beginners and those looking to structure their database knowledge or planning to develop in this direction.
In the image shown above, a database is used in a database management system (DBMS) for short, is a form of software that allows an organization to access and manipulate data that will be showcased in a form that is unable to be changed by other applications and users.
This chapter introduces the basic concepts of databases and database management system (DBMS), reviews the goals of DBMS, types of data models and storage management system.
A typical DBMS has a layered architecture. The figure does not show the concurrency control and recovery components. This is one of several possible architectures; each system has its own variations.
A database is one of the essential components for many applications and is used for storing a series of data in a single set. In other words, it is a group/package of information that is put in order so that it can be easily accessed, manage, and update.
Instructor: Laks V.S. Lakshmanan Textbook: Database Management Systems by Raghu Ramakrishnan & Johannes Gehrke 3rd Edition. Most (not all) of my slides are based on the above textbook.
This course will provide students with a general overview of databases, introducing you to database history, modern databasesystems, the different models used to design a database, and Structured Query Language (SQL), which is the standard language used to access and manipulate databases.
