Welcome, everyone. This is Dr. Super And today we will be going through our first lecture for our database class. I need to operate under the assumption that not everyone in the class has had experience with databases in the past. And so this first lecture is intended to bring everyone up to the same basic level of understanding with respect to several important database concepts. We have several objectives, which we will seek to achieve in this lecture. These are listed on the screen right now. First, we want to try to understand why storing data in a list is not necessarily a very good idea. It can cause many types of problems. Second, we want to see if we can gain some insight into why an organization might want to use a database. Third, we will see how the notion of related tables of data, which forms a core part of the relational database model, provides a basis for eliminating many of the problems which are associated with storing data in a list. We'll also explore the various components and elements that comprise a database or a database system. And we will learn about the purpose of something that we call a DBMS, a database management system. And along the way, we're going to explore some of the functions that a robust database application can provide to us. What, then, is the purpose of a database? Well, it's important to remember that a database does not have just a single purpose. Instead, there are several key advantages that databases provide. First, a database provides a repository for storing data. That's kind of implicit in the name. Database implies that we have a place to store data. However, what might not be so obvious is that databases provide an organizational structure for data. That is, we don't just have a place to store data, but the database also provides an organized structure into which those data can be placed. Finally, a database provides us with a mechanism for interacting with our data. Now, interacting with data can generally be described in four different operations. Here they're listed as querying, creating, modifying, and deleting data. But there's another more interesting acronym, which may help you to remember this. And that acronym is CRUD, C-R-U-D. This stands for create, read, update, and delete. These are the four basic operations that we can use when interacting with data. A key point to remember here is that, in business, there are many natural, hierarchical relationships among data. For example, a customer can place many orders. Another way of saying that is many orders can be associated with the same customer. Or another example is a department can have many employees, but a given employee might work in one, and only one, department. So these are hierarchical relationships among the data. And a relational database allows us to model and represent these relationships. Let's take a look at a list of data. What I mean by a list here is a simple, two-dimensional table of data. And in this table, we...
