Programming Languages and Their Use Cases

Every now and then, another rating of the most popular programming languages arrives, prompting decision-makers to question the choice of language for their new project. Luckily, various ratings by RedMonk, GitHub, PyPL Index, Tiobe, Stack Overflow and suchlike depict that the changes on the top 10 languages list are subtle. We have compiled our own go-to guide to the best coding languages in relation to the business challenges they address.


Factors to Consider

Before we proceed to the list, let’s explore the various factors that may influence our choice. Frequently, the team’s skillset is the only determinant. However, making the decision solely using this factor is likely to bring difficulties in the future.

On top of the existing team’s expertise, there are technical aspects that should be prioritized when deciding on a language:

  • Technological characteristics and performance capabilities of the language — elasticity, coding speed, performance, memory consumption, IDE availability, error handling
  • Technological considerations — infrastructure, platform, technology, legacy codebase, frameworks, architectural environment
  • Security considerations
  • Economic considerations — the costs of licensing, employee training and codebase migration
  • Legal considerations
  • Project’s business objective that the ultimate solution is expected to address

The business objective is the aspect that we would like to consider closely. In this brief overview, we will leave out the technicalities and focus on the most popular languages with respect to the business needs they meet.


С has influenced, directly or not, many others, including C++, C#, Go, Java, JavaScript, Objective-C, Perl, PHP, Python and Swift. Most of them inherited its control structure, syntax and some basic features.

High speed, stability, efficiency and availability are among the reasons why C is popular for addressing various technological and business challenges. Moreover, other languages’ libraries, interpreters, compilers and reference implementations are often written in C, which is why it is used as an intermediate language.


Released in the early 80s as the extension of C — “C with Classes” — C++ has significantly improved over time and has transformed into a high-performing language. A lot of vendors implement it as a compiled language — IBM, Oracle, Intel, Microsoft and others.

Like its ancestor, C++ was initially designed for system programming and embedded development. Now, its use spans resource-limited software — video games, desktop enterprise applications, servers — and high-speed applications. It is also a good choice for scientific computing and mathematical software.


Another offspring of С, C# was created as its incremental compiling version — even its name indicates it. Called after a musical note, the sharp sign depicts that this language is just a semitone different from its ancestor. The project has failed, but the name is still alive.

In 2001, Microsoft once again created the language for its .NET initiative, to develop software components that are deployed in distributed environments. Since then, C# powers solutions based on the .NET framework and serves enterprise and game development, data visualization and storage.


Go, frequently referred to as Golang, is a rising star, and we could not leave it out in the cold. Google’s pet project, this modern language was designed to create distributed systems and powerful software that can address “real-world challenges,” such as low-speed program setup, uncontrolled dependencies, duplication, cross-language interoperability and many others.

Since its creation in 2009, Go has been steadily gaining momentum, and it now occupies the 11th position in TIOBE Index for February 2020. Some experts predict that the chances that one day Golang will substitute C and C++ are high.


This general-purpose, object-oriented language named after coffee has been on the market since 1996 and is not about to roll over. In fact, statistics show that Java is the number one programming language when it comes to the number of job postings. Write Once, Run Anywhere, as Java’s slogan asserts — what this all about?

With Java, a business kills two birds with one stone: it can build any software, from comprehensive business systems to desktop software to robust Android-based mobile applications. This versatile language is also efficient in creating data visualization software, distributed systems, data storage solutions and Big Data management software.

No, JavaScript does not have any relation to Java, except that both of them have similar syntax and standard libraries — they are very different when it comes to other characteristics. JavaScript is a core web development technology that enables page interactivity. A large majority of websites rely on it to manage client-side behavior.

Over time, the use of JavaScript outgrew the client-side, and now it also spans the development of web and mobile applications, distributed systems, non-browser software and the server-side of website deployments.


The acronym PHP was originally short for “Personal Home Page.” Over time, it morphed into “PHP: Hyertext Preprocessor” — it is obvious that was designed for web development. Since its release in 1995, PHP has powered thousands of websites and is still the number one web development language. It continues to become ever more efficient, cost-effective and faster.

WordPress, Drupal and Joomla use PHP as the server-side language, with Facebook and Wikipedia relying on it as well. Besides its use in the web context, PHP also enables the development of graphical and drone control applications.

Amazing but true, this language was not called after a snake — instead, it’s named after Monty Python! For almost 30 years, Python has been proclaiming code readability and visual succinctness, heavy use of significant whitespace, English keywords instead of punctuation and logical coding as its design philosophy.

Python serves for a wide variety of purposes: the development of extensive web applications, data storage, Big Data processing, data science, data visualization, video games, artificial intelligence and machine learning, and information security. For many operating systems, Python has become a standard component. Also, it is the number one choice when it comes to script writing, complex structure rendering and natural language processing.


SQL, or Structured Query Language, was created almost 50 years ago to manage data that are held in databases and ensure the smooth communication of data repositories with other system components. Now, it is the standard language for relational database management systems.

RDBMS solutions from prominent market players, such as Microsoft, Oracle and Ingress, all use SQL; however, almost all of them combine it with their special-purpose proprietary extensions. A tool to query data from RDBMS, SQL also processes streams and handles structured data.


Developed by Apple as an alternative to Objective-C, Swift seems to eliminate the need for its predecessor. Sometimes called as “Objective-C without the C,” it operates under a principle of up-to-date programming concepts and has a simple syntax. Software for macOS, iOS, Linux and other native operative systems for Apple is the area on which Swift focuses.

Follow Your Goals

As it follows from the list, there is no one-size-fits-all solution. That is why we recommend going by a business goal that software is expected to support in the first place. Once you get a clear idea of a solution you need to develop, you can pick languages that can help you achieve it. Then, you can dig deeper and select the one that meets all your considerations — technological, economic, legal and security.

How Mobile Fits Into Your Centralized IT Strategy

Do you have a centralized IT strategy? If so, do you also have a mobile strategy? How does mobile fit into your overall centralized IT strategy? These are important questions to answer. According to PwC’s 18th Annual Global CEO Survey, 81% of CEOs see mobile technologies as strategically important for their organization. In addition, 86% say that a clear vision of how digital technologies can create a competitive advantage is key to the success of their investments. It’s great that most CEOs understand the importance of mobility. However, when it comes to the execution of mobile projects, app development becomes decentralized and fragmented. According to a report, 46% of CIOs say fragmentation is the reason why their mobile strategy lags behind. This can cause serious issues as a lack of a mobile strategy will lead to redundancy, inefficiency, uncontrolled costs, and even apps that fail. CIOs need to address the issue of fragmentation so that they don’t wind up overspending on enterprise apps that don’t even work.

IT Strategy

So what can CIOs do? First, you need to look at all current mobile apps that have been deployed, all applications, technologies, and also the policies and procedures that are set in place for employees. Is your company ready for mobility initiatives? Is the infrastructure in place to handle mobile apps and the technologies that go along with them?

If the organization hasn’t deployed any mobile apps, then it would be a good idea to start by creating an enterprise mobile strategy. In the strategy, you’ll need to identify areas in the business where mobile could enhance processes. To do that, you’ll need to get some researchers to conduct user research, which helps uncover areas where processes could be made more efficient. Investing in research early will improve the success of your mobile app. When creating your strategy, make sure that your mobility and company goals are aligned. This will help you when it comes time to design and develop your mobile apps. By having aligned goals, the mobile agency will be able to create apps to help you reach your KPIs. Creating a mobile app isn’t as simple as you’d think especially if you want the app to transform your business processes.

If your company has mobile apps already, it would be a good idea for you to figure out the personas and how they are using mobile. For example, are warehouse managers using mobile apps to ensure that inventory levels are correct? Are you using mobile to make sure that all products have been inspected and are of high quality? Are these mobile apps designed so that they can actually enhance and improve work or do they just add more stress to workers? Also, is the user experience consistent throughout all apps and technology at the company? Creating a great user experience is key especially in getting your workers to adopt and actually use these mobile apps. Your apps need to be able to sync information to a central database and to your existing systems.

One important area to consider when aligning your mobile and IT strategies is the policies and procedures that will be used to govern these technologies and users. One way to govern these policies and procedures is by creating a Mobile Center of Excellence or MCoE. An MCoE can ensure consistency for all your mobile projects across your organization and tie everything back to your core business objectives.

Security is a huge issue and users need to understand how apps can be used so that data doesn’t accidentally get leaked out. Even if the information does get leaked out, your company needs a plan in place to fix the issue quickly so that data won’t get into the wrong hands. To protect your company, you should apply enterprise mobile security best practices such as using multiple forms of authentication, creating separate, secure mobile gateways, and performing regular mobile security audits. In addition, you should use a mobile application management system (MAM) and mobile device management (MDM), provider. What is the difference between a MAM and MDM? A mobile application management system or MAM helps companies control individual apps and user authentication. Mobile device management or MDM provider gives IT control over devices so if a mobile device is lost, it can be remotely wiped so that all private company data can be removed. Just having a MAM or MDM may not be enough though – you will need to integrate all your mobile devices into a centralized vulnerability management strategy. Taking these steps will help your company protect its data and lessen the impact of security breaches.

By including your mobile strategy into the company’s centralized IT strategy, you’ll be able to align your goals for mobility with your company’s overall goals. Want to learn more about creating a mobile strategy? Check out our guide below.
