IBM Db2

When I was in need of a database which can support mission-critical application, IBM DB2 came to rescue.

Let’s discuss about this hero in details.

IBM Db2 is a cloud-native database designed to support high-volume, low-latency transactions and real-time analytics. It gives DBAs, corporate architects, and developers a single engine to keep important applications running, store and query anything, and fuel faster decision making and innovation across your organisation. Built on decades of data security, scalability, and availability innovation, keep your apps and analytics secure, highly performant, and resilient anywhere.

First thing first, when i talk about mission-critical application, let’s see what offering from DB2 i have used most extensively.

Db2 is really powerful and scalable database that can be used for a variety of applications, including:

1. Online transaction processing (OLTP)
2. Online analytical processing (OLAP)
3. Data warehousing
4. Big data analytics
5. Hybrid cloud deployments

Db2 offers a wide range of features, including:

1. ACID transactions
2. High availability and disaster recovery
3. Scalability and performance
4. Security and compliance
5. Advanced analytics

At this time, I am pretty sure you are interested to see a sample query, let’s see.

SELECT * FROM employees; 

This query will select all rows from the employees table.

Here is another sample query that selects the first name and last name of all employees who are from the United States:

SELECT first_name, last_name
FROM employees
WHERE country = 'United States'; 

You can also use the WHERE clause to filter the results of a query. For example, the following query selects all employees who have a salary greater than $100,000:

SELECT *
FROM employees
WHERE salary > 100000; 

You can also use the ORDER BY clause to sort the results of a query. For example, the following query sorts the results of the previous query by the employee’s last name:

SELECT *
FROM employees
WHERE salary > 100000
ORDER BY last_name; 

These are just a few examples of sample queries in IBM DB2. There are many other types of queries that you can use, depending on your specific needs.
