It includes hands-on examples and activities. IBS DB2 helps us to deploy and build critical applications in our organizations. DB2 supports the OLAP and OLTP types of operations and handles two kinds of workloads.

DB2 Tutorial Explain

The DB2 tutorial provides us with the advanced and basic concepts of the DB2 database. We can design DB tutorials for beginners as well as experienced people. DB contains the database server, and IBM Corporation developed it. It is a relational management system that stores, manages and retrieves data quickly. DB2 tutorial includes the DB3 tutorial includes multiple topics.

The DB2 tutorial includes the topics such as why we use DB2, what is the use of DB2, how we can install the DB2, how we can create the database by in DB2, how we can connect to the DB2 database, what is activate and deactivate database, how we can configure the database, how we can configure the database manager in DB2, how we can create tables in DB2, how we can list the tables in DB2, what is triggers in DB2, what is indexes in DB2, what is constraints in DB2, what is views in DB2, and what are sequences in DB2.

Why do we need to learn DB2 tutorial?

DB2 is the family of DBMS, and all sizes of organizations use this database. DB2 provides the transactional and analytical operations on data to keep the analytics efficient and transactional workflows. DB2 offers integrated support of the NoSQL capabilities that include the graph store, XML, and JSON. DB2 is a group of data that is collected in a unit. The DB2 database is a large data set whose primary purpose is to store the specified information.

The DBA uses the DB2 to create and use the DB2 database. The DB2 database operates on the server to manage the DB across multiple environments. DB2 database enables multiple concurrent users to access data. DB2 prevents unauthorized access. Also, it will provide utilities to back up the data that offer data management capabilities. DB2 database contains a logical structure that DBMS manages separately.

The physical storage of data is managed in DB2 without the effects of any logical storage structures. DB2 database is created from DDL language commands and is composed of the tables, tablespace, rows, columns, views, indexes, procedures, and other structures of SQL language.

DB2 offers multiple features to improve data and database management, including actionable compression, which delivers storage space. In DB2, multiple query predicates are evaluated without any decompression of data. HTAP performance is accelerated from the DB2 column to store the instruction on various data.

Applications

Below are the applications of the DB2 database. Below is the application of the DB2 database as follows. We can create multiple applications in the DB2 database.

Internet bookshop – This application contains a simple website of bookshops. We can search the database as per books. We can also create a new account and add items to the basket, then place the basket items order.
Student registrar – This application allows students of college universities to view their scheduled courses; they can sign up for new classes and modify the existing schedule.
Internet airline – This is a simple airline website. We can also create a new account and book the ticket.
Online pharmacy – This application allows doctors and patients to create online orders.

At the time of installation of the applications, we need to install the DB2 database in our system. The figure below shows how we can download the IBM DB2 in our system.

We can also create the DB2 application to use the IBM cloud. The below figure shows how we can make the DB2 database application use the IBM DB2 cloud as follows.

Example

To create the database in DB2, we need to execute create database command. To activate the database, we need to manage to activate the power. To deactivate the database, we need to use deactivate control.

To create a database in DB2, we need to use the below command. Below we have created a non-restrictive database name as a test as follows.

db2 create database test

To create a database in DB2, we need to use the below command. Below we have created a non-restrictive database name as a test1 as follows.

db2 create database test1 restrictive

Below we have activated the test database. To activate the database, we need to execute the below command as follows.

db2 activate db test

Below we have activated the test database. To activate the database, we need to execute the below command as follows.

db2 deactivate db test
