So far we’ve learned about the very basic concepts of Db2, but now I want to dive in a bit and work with tables. Some of the material in blog may take a few more blogs to fully understand, but that is okay. The goal is to get you started. Later we will come back and learn all the details.
We will be using SQL (Structured Query Language) to communicate to our database. DSM (Data Server Manager) is the UI (user interface) that we can use to work with our database, but we should do as much as we can with SQL. Why use code when there is a user interface? I’m glad you asked.

Before building a database for yourself or a corporation, you need to understand a bit about database structure.
We are going to go in some depth on how to design a database, which deals with structuring your database the best way possible. However, I thought it would be appropriate to give an overview of the Db2 structure and start using the database right away.

First off, what is a database? A database stores data, which is any information that might be of use to a company.
Db2 is a database created by IBM that is best known as an enterprise database, so we are talking about a database used by huge companies who have more data than they know what to do with. The great part for us is that that there are multiple editions of Db2 going all of the way up to the enterprise editions, but actually starting with a completely free version. That’s what I’ll be using.
So back on the topic of data. A database will often be used behind the scenes when you are using some software. Anytime you put information in software that you can access at a later time, that information will be stored in a database.
