Software development technologies
 Wide variety
 Constantly changing
 Constantly updating
Software development I
Software development – is a development of a software product.
Most methodologies share some combination of the following stages
of software development:
 Analyzing the problem
 Gathering requirements for the proposed business solution
 Devising a plan or design for the software-based solution (e.g.




choose tools)
Implementation (coding) of the software
Testing the software
Deployment
Maintenance and bug fixing
Software development II
Software types
 Internet
 Application
Software accessibility types
 Closed source
 Open source
 Free source
 Shareware
 Freeware
 Warez
History of software development
1940 – the beggining of software developement technologies
----1954 – FORTRAN
1958 – ALGOL
1959 – COBOL
1972 – Plankalkul
1975 – Ada
...
Now – Object Oriented programming languages
Programming languages I
 C++
• general-purpose ,object-oriented programming language
• one of the most popular programming languages and is
implemented on a wide variety of hardware and operating
system platforms.
 C#
• object oriented programming language
• developed by Microsoft within its .NET initiative
 Visual Basic
• object oriented programming language
• designed to be relatively easy to learn and use
Programming languages II
 Java
• general-purpose, object-oriented programming language
• intended to let application developers "write once, run
anywhere"
 PHP
•open-source server-side scripting language
• while PHP originally stood for Personal Home Page, it is
now said to stand for PHP: Hypertext Preprocessor
 HTML
• main markup language for creating web pages
• purpose of a web browser is to read HTML documents and
compose them into visible or audible web page
Programming languages III
 CSS
• style sheet language used for describing the presentation
semantics
• designed primarily to enable the separation of document
content from document presentation
 XML
• markup language that defines a set of rules for encoding
documents
• design goals of XML emphasize simplicity, generality, and
usability over the Internet
 JavaScript
• interpreted computer programming language
• originally implemented as part of web browsers so that clientside scripts could interact with the user
Programming languages IV
 jQuery
• open source multi-browser JavaScript library
• designed to make it easier to navigate a document, select DOM
elements, create animations, handle events, and develop Ajax
applications
 AJAX
• Asynchronous JavaScript and XML
• web applications can send data to, and retrieve data from,
a server asynchronously
 Flash
• multimedia and software platform
• used for authoring of vector
graphics, animation, games and Rich Internet Applications
Programming environments
Most popular programming languages
Conclusions
 According to the usage purpose software can be divided into
internet and applications;
 There are different levels of software accessibility
 It is important to choose software development technologies
before creating a program;
 According to TIOBE programming society the most popular
programming language is Java.
