Application Development and Programming Languages - Essay Example

Application Development and Programming Languages Object oriented language and imperative language differ from one inmany way as follows; Programmability of programming language refers to the ability of that language to modify itself as per the programmer’s requirements. Object oriented programming language, like java, provides an easy programmability procedure. Codes developed in one module can be reused in another module. The modules are easy to develop as they use real world objects, compare to imperative language like Pascal where code are written from top to bottom and, there is no reusability of the codes.

Maintainability is the ease with which a programming language can be maintained so as to find out bugs or their cause, correct the bugs or their cause. It is easier to maintain a well design and implemented object-oriented system than well designed imperative system. This is due to the facts that object oriented language is more complicated than imperative language because of the use of polymorphism and inheritance; these make it difficult to identify errors and their causes as it cause indirection in the program.

All system implementation requires both good interactive performance and good run time performance. It is difficult to satisfy these needs using a pure object oriented language since it requires a lot of optimization such that interactive performance suffers; the performance can be improved by adopting adaptive recompilation which helps improve the system’s responsiveness to programming changes. Lack of dynamically dispatched calls in an imperative language like C improve performance since they do not encourage factoring codes into small, reusable units, thereby reducing the frequency of the expensive operations.

Frequent calls not only hinder optimization and slow down execution with dispatch overhead per second. Imperative language uses top-down programming development tool where a problem is broken down into several pieces and work on each piece separately. This makes other project work difficult to reuse. Object oriented language use object which are modules containing data and subroutines, the object can communicate with one and another through Message passing and can be reused. Object that contains same data type and do respond to the same message is of the same class.

Scripting language supports scripts and is a high level programming language. It is interpreted and executed at run time rather than allowing traditional compilation by computer’s processors. Client-side scripting languages affect the data as seen by end user of a web page. Examples are JavaScript, Ajax. Server-side scripting language manipulates data in the database, on the server. Examples are PHP, ASP. The scripting language is added within HTML tags to add functionality to a web page like serve dynamic advertisements, graphical displays or different menu styles.

Scripting language that I will use to develop a highly interactive Web application is JavaScript; it will make the application more dynamic as I can create special animation on web pages like rollout, rollover and other types of graphics that would leave an amazing on the applications’ users mind. JavaScript is also used for validation purpose. Integrated development environment was at first possible when developing using terminal, which were not supported by early system as they used to enter programs with punched cards before compiling them.

The first integrated development environment was Maestro I, developed in 1970s. Soft bench was one of the first integrated development environment with plug-in. Today most of them are menu-driven and with a lot of graphics like Eclipse, Netbeans. There are many reasons for using IDEs as the allow autocomplete, these make one not necessary remember all the code procedure. Visual debugger enables one to find errors from the codes easily. Furthermore, it allows source control as one check the changes, add files to the commit, write a comment and push it.

Lastly it enables doing all the work in the same platform. The IDE that I will use is Netbeans as it is easy to interact with and provide many palettes components that I can utilize in developing Java, C, C++ and PHP applications. It also allows me to organize my project files and identify coding errors in each file that may occur. Netbeans also uses colour syntax code for easier reading. Reference Agrawala, A.
