This is the world's biggest roadmap for learning all about databases, their basic concepts, and their types. It is made for beginners to help them learn the most important skill that is used in every software, website, and mobile application.
A database is a collection of data that is organized in a structured way so that it can be easily accessed, managed, and updated. A database typically contains multiple tables, which are organized into rows and columns. Each table contains data on a specific topic or category, and the columns in a table represent the different attributes or characteristics of the data in that table.
For example, a database for a library might have a table for books, a table for authors, and a table for patrons. The book's table might have columns for the book's title, author, publication date, and ISBN number, while the author's table might have columns for the author's name, birthdate, and biography. The patron's table might have columns for the patron's name, address, and library card number.
