2. Software development technologies Wide variety Constantly changing Constantly updating

3. 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

5. Software types Internet Application

6. Software accessibility types Closed source Open source Free source Shareware Freeware Warez

7. 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

8. 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

9. 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

10. 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 client- side scripts could interact with the user

11. 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
