If you want to learn IBM DB2, you’ve come to the right place. This document will give you an overview of what you need to know to get started.
Getting Started:
Before you can start learning IBM DB2, you need to have a basic understanding of databases and how they work. If you’re not familiar with databases, we recommend that you read our Introduction to Databases article before proceeding.
Once you have a basic understanding of databases, you’re ready to start learning IBM DB2. The best way to learn any new software is by using it, so we recommend that you install the free IBM DB2 Express-C edition and follow along with the examples in this document. You can ask the Remote DBA Administrator for more details.
Basic Concepts:
Before you can start using IBM DB2, you need to understand some basic concepts.
Databases:
A database is a collection of data that is organized in a specific way. A database can be as simple as a list of names and addresses, or it can be much more complex.
DB2 is a relational database management system (RDBMS). This means that it stores data in tables, and you can use SQL to query the data in those tables.
Tables:
A table is a collection of data that is organized into rows and columns. Tables are similar to folders in a filing cabinet – they help you keep your data organized so that you can find it easily.
Columns:
A column is a piece of data in a table. Each column has a name, and all the data in that column must be of the same type (for example, all dates or all numbers).
Rows:
A row is a collection of data in a table. Each row represents one record in the database. For example, if you had a database of customer information, each customer would be represented by one row in the database.
SQL:
SQL (Structured Query Language) is a language that you use to query databases. SQL is very powerful, and it can be used to do things like select specific data from a database, update data in a database, or delete data from a database.
If you’re not familiar with SQL, we recommend that you read our SQL Tutorial before proceeding.
Now that you understand some of the basic concepts, you’re ready to start learning IBM DB2.
Installing DB2:
The first thing you need to do is install DB2 on your computer. The easiest way to do this is to download and install the free IBM DB2 Express-C edition.
Once you have DB2 installed, you’re ready to start using it.
Creating a Database:
The first things you need to do when using DB2 is create a database. A database is a collection of data that is organized in a specific way. You can think of it as a folder on your computer where you keep all your files organized.
To create a database, you need to use the CREATE DATABASE SQL statement. For example, to create a database named “my database”, you would use the following SQL statement:
DB2 is a relational database management system (RDBMS) that supports the structured query language (SQL). DB2 is produced by IBM.
There are several ways to learn about and use DB2. You can attend a formal training course, read a book, or use the IBM Knowledge Center. This document describes how to get started using DB2.
The first step is to install DB2 on your computer. You can download a free version of DB2 from the IBM website. Once you have installed DB2, you need to create a database. You can use the IBM Data Studio tool to do this, or you can use the command line.
Once you have created a database, you can start adding data. You can use the Data Studio tool to do this, or you can use the command line.
Once you have some data in your database, you can start querying it. You can use the Data Studio tool to do this, or you can use the command line.
Conclusion:
DB2 is a powerful database management system that is easy to learn and use. You can install a free version of DB2 from the IBM website, and you can use the Data Studio tool to manage your databases.
