DB2 vs MS SQL

DB2:

IBM developed the Database named DB2. It is a database that follows relational database management system principles. By using DB2, we can fetch the data, analyse it and store it efficiently. DB2 is based on Object-Oriented features and non-relational XML structures. It is a group of related data management products that include data servers developed and marketed by IBM. It is developed on a concept based on SQL, i.e., standard query language on the relational database system, which means DB2 uses SQL queries to retrieve and store the data into the Database. We can use DB2 on AS/400 IBM mainframe and personal computers.

DB2 also supports the storage of non-relational formats like XML and JSON DP. It is not open-source but provides some free distributions, and IBM fully owns it, and if we want to run on large servers, we should have to pay for the licensing.

Let's see some advantages:

DB2 has been around for years and has matured as a robust RDBMS.

1. Powerful Structures Query Language

2. Various Platform support.

3. IBM Support

4. Fetching of data is significantly fast

5. It provides high security

6. It is independent

7. It provides very high concurrency, Allowing multiple applications and users to access the data parallelly and Concurrently.

8. Redundancy is low

9. It provides flexibility with the designs

10 It offers easy access, and user is not required to know the physical relationships of the Database they wish to access

11. It is reliable, secure and offers high availability

12. It can efficiently handle large volumes of data

13. It can work with various operating systems

What is SQL Server:

It was released approximately 32years ago as a relational database management system. It is used for other applications to perform storing and fetch information. It was initially named SQL server 1.0 by Microsoft. It consists of a 16bit server and operating system OS/2. It has various versions launched to date. It has launched editions for 2-5 users and individual users like Standard, Web, and Enterprise. Workgroup and Express were launched for business. It also provides special editions that offer cloud-based services, and they are known as Azure.

All the communications and operations performed by SQL with the client are stored and sent to Microsoft via the application Tabular Data Stream. TDS is an application that serves the service of transferring data between the server and a client. It is present in various languages like English, Chinese, Spanish, Russian, Japanese, and many more.

Both the servers DB2 and SQL are better in their ways and offer unique features. Working on a Windows SQL server compared to DB2 or other servers offers speedy access to the data. However, both the servers offer a Graphic user interface to the users. Speaking of the cost of the license, DB2 is expensive for SQL.

When purchasing the SQL server licenses, it contains four products: Analysis services, Integration services, Database engine, and reporting service. While in DB2, we have to pay for four products separately. The drawback of DB2 is we need an Enterprise edition server while SQL can be used on laptops and personal computers.

Disadvantages of DB2:

- The delivery of developer tools by IBM is late.

- The BIND is time-consuming

- It is a little behind in rolling out the next-generation features.

Disadvantages of Microsoft SQL Server:

- The importing and exporting process is tricky; it consists of a lot of steps and is better for flat files.

- Getting help form microdot is complicated other web sources are speedy.

- The documentation is not proper; we can get a better explanation elsewhere
