A database is an organized collection of structured information, or data, typically stored electronically in a computer system. As per the database diagram, the data can be easily accessed, managed, modified, updated, controlled, and organized. It should be noted here that most databases use structured query languages (SQL) for writing and querying data. As the course choosing database diagram image shows, databases are designed to hold larger collections of organized information as it allows multiple users at the same time to quickly and securely access and query the data using highly complex logic and language.
