Why is COBOL Still Used? Get Expert Advice

COBOL is a programming language that was designed exclusively for the business industry. It was the first-ever high-level programming language that was simple enough for people to read and write. COBOL is like the English language is structured the same way and can be understood by people who are not technical experts. The USA's Department of Defense introduced COBOL in 1959 to serve as a common language for business applications. Large companies generally use it in their financial and administrative systems because it is so easy to read and update.

COBOL has been around for over 60 years because of a few key reasons.

1. Dependable Systems

Banks and government offices rely primarily on COBOL systems established many years ago. These systems have already become, thus, deeply incorporated into their everyday activities, so it is supposed to be null and void if the institutions attempt to rebuild them anew. Using COBOL technologies improves the running of the affiliates, and thus, it has become an irreplaceable component of these organizations.

2. Cost Efficiency

Fixing and updating COBOL systems usually costs less than developing new systems. The approach favors companies that do not have to build new software. Replacing COBOL systems would be prohibitively expensive so most companies continue to use and modernize them instead.

3. Proven Stability

COBOL is very reliable in handling large transactions almost with zero errors. Thus it becomes an undisputed option in tasks of utmost importance where data precision is a must. COBOL is an aged and superior language that can handle big data tasks without a problem.

4. Skilled Workforce

Even though it seems like there are fewer COBOL programmers, there are still many skilled people who know this language. Many companies train new workers to keep their IT operations running smoothly, making sure there are always capable COBOL programmers available.

While COBOL is old, it has kept up with new technology to stay useful.

1. Integration Capabilities

COBOL can operate alongside modern systems and databases, which allows companies to include new features without rearranging everything. This also enhances businesses' COBOL applications with the latest technology. For instance, COBOL is compatible with modern APIs and cloud-based services, which simplifies organizations' work by introducing new technologies.

2. Cloud Computing

Some companies are making a migration of their COBOL applications to the cloud. This makes them more scalable and better for disaster recovery, but the reliability of COBOL still remains. Migration to the cloud allows companies to save bucks and work better with heavy operations. Cloud computing also has better security and compliance functionalities which are very important to many sectors.

3. Continuous Improvement

One of the ways COBOL has been able to keep abreast is by making some changes to the language one of which includes the use of new compilers. There are COBOL compilations that can be used in modern programming methods. This has allowed COBOL to be integrated into new development environments, enhancing COBOL’s relevance. Glacier Point was COBOL’s first attempt to modernize a language that was, in the past, rewritten anew from scratch to become current with the technology of the day. This occurs because companies will need to use applications that can interact dynamically with one another. But even this access nowadays can succeed off one resource only so cloud computing and SAAS have become very popular concepts.

Even though COBOL is old, learning it can be useful, especially for those interested in working with legacy systems or industries that still rely on COBOL.

1. Online Resources

There are many online tutorials and courses for learning COBOL programming. These are good for beginners and experienced programmers. These resources allow for self-paced learning, making them accessible to everyone. Websites like Udemy, Coursera, and even YouTube offer courses on COBOL programming.

2. Educational Programs

Some universities and technical schools offer courses in COBOL programming. These programs ensure that new generations of IT professionals can maintain and develop COBOL systems. Various professional training programs focus on COBOL, providing intensive learning opportunities for those aiming to specialize in this language.

3. Community Support

There are communities of COBOL developers who offer support and share knowledge through forums, user groups, and networks. These communities help learners and professionals stay updated with best practices and new developments in COBOL programming. Websites like Stack Overflow and GitHub have active COBOL communities where developers can ask questions and share their knowledge.
