Databases

• What are Databases? Databases are structured sets of data. They are used to store, manage, and retrieve information. Databases can handle anything from a small amount of data, like a contacts list on your phone, to large amounts of information, like the entire inventory of an online store.

• Why are Databases important? Here are some key reasons:

  • Organization: Databases provide a structured and efficient way to store and retrieve data.
  • Accessibility: They allow multiple users to access and manipulate data simultaneously.
  • Security: Databases offer features to protect data, including access controls, backup and recovery systemss, and data integrity checks.

• Example - Using Databases in Personal Infrastructure: Suppose you have a large collection of digital photos. You could use a database to organize these photos, making it easy to find specific images. You could store details about each photo, such as the date it was taken, the people in the photo, and the location. This would allow you to quickly find all photos from a specific trip or featuring a particular person.
