View (database view)

In business intelligence and data analytics, a view when talking about databases, is like a customizable snapshot of a more complex data set. It’s not a physical copy, but rather a saved query that lets you look at specific slices or aspects of the data without having to sift through the whole database every time. Imagine if every time you wanted to read a book, you could automatically flip open to your favorite chapter—that’s what a database view allows users to do with their data.

Views are really handy because they let you focus on just the bits of data you need. For instance, if you’re only interested in seeing sales data from the last quarter, you can create a view that shows you only that. The beauty of a view is that it’s dynamic; if the underlying data in the database changes, so does the data in the view. This means you’re always looking at the most current information without the need for manual updates.

Using views is also a smart move for security and efficiency. You can give team members access to just the data they need without exposing sensitive information that’s not relevant to their work. Plus, because views are based on queries, they don’t take up extra storage space in the database. They’re an essential tool for data professionals who need to turn complex databases into clear and useful information, helping businesses make informed decisions quickly and safely.
