Difference Between Db2 and SQL Server (With Table)

In the world of computers, Servers play a crucial role. The term server means to give/provide services. A server can be a part of a hardware or software doesn’t matter, but its main work is to provide the functionality to other programs present in the computer known as clients. The whole structure works based on a client-server model. There are different kinds of servers such as database server, mail servers, print servers, game servers etc. Db2 and SQL Server are part of the database servers.

Db2 vs SQL Server

The difference between Db2 and SQL Server is that both are developed by different companies. One is being developed by IBM, and the latter is being developed by Microsoft Corporation. While Db2 is a family of data management, which includes database servers as well. SQL is a Relational Database Management. There is also a difference in the operating system. While SQL uses Linux and Windows, Db2 uses AIX, HP-UX, Linux, Solaris, Windows, z/OS.

Db2 is a group of database management system including database server as well developed by IBM Company in the year 1989. Earlier it supported the relational database management system, but now it is changed to support an object-related database management system. Db2 was released as a platform-specific product to support different operating systems.

SQL is a relational database system by Microsoft Corporation in the year 1993. It is a software product that has a database server as well. Its main function is to store and retrieve the data from the servers. Microsoft has launched different editions of SQL server to serve different audiences and cater to their needs.

What is Db2 Server?

Db2 Server is a system that uses hybrid data to simplify and unify the entire core or system of database management. Apart from these, Db2 also allows different functions such as access, sharing and analyzing the data of any type, whether it be structured, semi-structured and unstructured. Wherever the information is stored in Db2, it will perform the same functions mentioned above.

Db2 was launched in the year 1993. It comes in the size of 1.6 GB. It is written in the language C, C++, Assembly and Java. Db2 has APIs and other methods which can access that includes JDBC, JSON, ODBC, ADO.NET, style queries, and XQuery. Its secondary database models include Document and RDF store. It is available in the English, Spanish, French, German, Russian, Japanese language. The family of Db2 includes Db2 Database, Db2 Warehouse, Db2 on Cloud/Db2 Hosted, Db2 Warehouse on Cloud, Db2 Big SQL and Db2 Event Store.

Db2 supports the Sharding Partitioning method. It also supports the coalescence of the Eclipse and Visual Studio integrated development environments. One of the features of Db2 is to handle the error in computer programs. It was developed by a researcher named Edgar F.Codd, working in IBM in the 1970s.

What is SQL Server?

SQL Server, released by Microsoft almost 32 years ago, is a relational database management system. It is software that does the function of storing and retrieving the information for other applications. SQL Server was the first SQL product of Microsoft named- SQL Server 1.0. It has a 16-bit server and OS/2 operating system and works even to date. 

Microsoft has launched different edition for different users. For 2-5 or individual users, it has launched mainstream editions such as Enterprise, Standard and Web. For businesses, it has launched Workgroup and Express. SQL also has some specialized versions which provide cloud-based service known by the name Azure. 

All the things which SQL does or communicate with its clients are recorded or sent to Microsoft through Tabular Data Stream(TDS). 

TDS is an application that transfers data between a database server and a client. SQL is available in many languages like Russian, Spanish, English, Chinese, Japanese etc. Formally it was written in C & C++ languages. It can run on a different system that was earlier not possible such as AIX, HP-UX, Linux, Solaris and Windows.

Main Differences Between Db2 and SQL Server

  1. Db2 is developed by IBM. SQL is developed by Microsoft Corporation.
  2. Db2 was released in the year 1989.SQL was released 3 years after Db2 released i.e. 1993.
  3. Db2 has an operating system that works on Unix-like, Linux and Windows. SQL works on many operating systems such as AIX, HP-UX, Linux, Solaris, Windows, z/OS.
  4. DB2 is written in many languages C, C++, Assembly and Java. Initially, SQL was written in only two languages: C & C++.
  5. Companies like Wells Fargo, Citi, JPMorgan Chase etc., use the Db2 server. Companies like Wells Fargo, Citi, JPMorgan Chase uses the SQL server Bank of America, UPS etc. Bank of America uses both servers.

Conclusion

Both SQL and Db2 servers are good in their way and have their unique features. SQL server, in comparison to Db2 and other servers, provides faster access to the data while working on Windows. While SQL and Db2 both provides a Graphic User Interface (GUI) to their users. If we talk about taking the license of these servers, then Db2 is much costlier than SQL.

Db2 Server for 10 users cost 2 lakhs approx. SQL Server for unlimited users cost 2 to 3 lakhs. SQL Server comes in a bundle containing 4 products, namely, Database Engine, Analysis Services, Reporting Service & Integration Services. In Db2, all 4 products have to be purchased separately. One of the drawbacks of the Db2 Server is that it requires an Enterprise edition server, whereas SQL can run on any laptop or computers. If we count pros and cons of both SQL server is much better than Db2.
