Understanding how relational databases evolved is critical to knowing which platform will best suit your needs in the future. In this video take a look at how relational databases have changed over time and where they might go in the future.
- [Instructor] It's important to understand where AgeBase…differs from a regular relational database,…so let's take a look at that.…And first I want to understand where relational databases…came from and what their main function is.…So a Relational Database Management System is…comprised of several different components here.…First, we have tables and views which are…the logical storage units of data.…Inside of those Tables and views, you have Rows and columns.…Which are similar to what you find in an Excel spreadsheet.…
In the Tables and views you have primary keys, foreign keys,…which define relationships between…different objects in your database.…Each column in the Table or view has a datatype…associated with it, so programming languages can…understand exactly what type of data they're going to get…back when they ask for it from your table or view.…One unique property of Relational Database Management…Systems is that they all support a standard version of…the programming language SQL, it stands…for Structured Query Language.…
