7 Software Development Models You Need To Know

2. HTML and CSS

HTML (HyperText Markup Language) is a software engineer programming language designed to create web pages which are pieces of information presented on the World Wide Web.

Advantages of HTML:

  • The language is widely used with lots of resources supporting it and a huge community behind it.
  • Can work smoothly on almost any current browser.
  • The process of learning HTML is quite simple.
  • Open source and completely free.
  • Markups used in HTML are usually concise and uniform.
  • The World Wide Web Consortium (W3C) operates the main web standard.
  • Easy to integrate with backend languages ​​like PHP, Node.js,…

Disadvantages of HTML:

  • This language is mainly applied to a static website. For dynamic features, you need to use JavaScript or a 3rd party backend language such as PHP.
  • Users must create individual web pages for HTML, even if the elements are the same.
  • Some browsers are slow to accept new features. Sometimes older browsers don’t always display the newer tags.

CSS (Cascading Style Sheets) is the definition of how an HTML document should be displayed. CSS is especially useful in Web design. It makes it easy for designers to apply the designed styles on any page of the website quickly and synchronously.

Advantages of CSS:

  • The ability to save time
  • CSS for fast page loading
  • Easy to perform maintenance
  • CSS has the wide property
  • Good compatibility
  • Disadvantages of CSS:
  • CSS works differently for each browser
  • This software engineering language is quite difficult for newbies
  • The format of the web is potentially at risk

3. JavaScript

JavaScript is a popular programming language used to create interactive web pages. It is integrated and embedded in HTML to make the website come alive. JavaScript acts as part of the web page, and the executable allows Client-Side Scripts from both the user side as well as the server side (Nodejs) to generate dynamic web pages. It is an interpreted programming language with object-oriented capabilities, which is one of the 3 main languages ​​in web programming interrelated to build a vibrant, professional website.

The advantages of using JavaScript are:

  • Less server interaction – You can validate user input before sending the page to the server. This saves server traffic, which means less load on your server.
  • Immediate response to visitors – They don’t have to wait for the page to reload to see if they forgot to enter something.
  • Increase interactivity – You can create interfaces that react when the user hovers over them or activate them via the keyboard.
  • Richer Appearance – You can use this software engineer language to include items like drag and drop elements to slide the Rich
  • Appearance for your website visitors.

Limitations of JavaScript:

  • The client-side does not allow reading or writing in the file. This has been kept for security reasons.
  • Cannot be used for network applications because there is no such support.
  • Doesn’t have any multithreading or multiprocessing capabilities

4. Java

Java is known as a high-level, object-oriented, and strong security language, it’s also defined as a Platform. Java was developed by Sun Microsystems, started by James Gosling that released in 1995. Java works on many platforms such as Windows, Mac, and different versions of UNIX. It is a purpose-built programming language, developed for distributed environments and software processes. The language is an independent platform, with no restrictions on any particular hardware or operating system. It provides users with the facility to be able to “write once, run anywhere”.


  • Java is an independent platform.
  • Java is an object-oriented software engineer language.
  • The main reason for Java’s safety is Java doesn’t use pointers.
  • Java can achieve multithreading.
  • Java is powerful because it has many features like garbage collection, no pointers, and exception handling.
  • Java is an easy-to-understand language.
  • Efficient memory management is implemented using the Java Programming Language.


  • Poor performance, invalid caching configuration, and deadlock between processes.

  • Although the use of this type of language is said to be simple, the learning process can be difficult, especially in the setting environment.
    Ruby’s syntax is biased towards freedom, so it’s inconsistent and difficult to manage.
  • Programmers can take a long time to read and understand Ruby code written by others. Therefore, it takes time to edit later.
  • Ruby is a scripting language, so it runs slowly. Therefore, Ruby’s problem-solving time is still much slower than some other programming languages.

6. PHP

PHP stands for Personal Home Page which has now been converted to Hypertext Preprocessor; is one of the multi-purpose scripting software engineering languages. PHP is commonly used for developing server-side web applications. Thus, the PHP programming language can handle functions from the server side to generate HTML code on the client such as collecting form data, modifying the database, managing files on the server, or other operations.


  • First of all, PHP is open source. So the installation and use of PHP language are very easy and the most popular installation is on popular WebSevers such as Nginx, and Apache.
  • It’s a free source code and it’s shared a lot on forums so you can easily copy and install it using existing websites or contexts.
  • PHP is easy to learn and easy to use, it has great flexibility for solving problems
  • This is a language with the largest community today
  • High-security capabilities with different security layers make the website’s operation more stable and secure.

  • Only partial control: Due to many security rules in the enterprise, databases will not be fully controlled.

8. C

C is the world’s most popular programming language, which is simple and flexible to use. It is a structured independent programming language and is widely used to write applications, operating systems such as Windows, and many other complex programs such as Oracle database, Git, Python Interpreter, etc.

In addition, many programmers, when learning C programming, refer to C as the “mother language”. Because C is the basis and foundation for other languages, and if the programmer learns C programming well, other languages ​​such as C++, C#, and Java can be easily conquered.


  • High performance
  • Flexibility:
    – C can be used to write applications on 8bit microcontroller systems and can also be used for applications on 64bit systems, or supercomputers all that is needed is a suitable compiler.
    – Ability to execute algorithms
    – C also provides a standard library with hundreds of functional functions, math tools, and more.
    – Logical syntax


  • The size of the array must be fixed
  • The array allocation memory bytes are sequentially sorted
  • Inserting and deleting elements of an array takes a long time

9. C++

C++ is an object-oriented software engineering language developed by Bjarne Stroustrup. It is developed on the foundation of the C programming language, so C++ has both programming styles like C. It is considered a “hybrid” language and a middle-level language because it has the properties of both low-level programming languages ​​(Pascal, C…) and high-level programming languages ​​(C#, Java, Python…).

C++ programming language has the extension .cpp


  • C++ is an object-oriented programming language
  • C++ allows comfortable memory management
  • C++ is a low-level language that easily interfaces with hardware
