Application Programmers Overview
Application Programmers are virtually the computer-physicians, knowing exactly what kind of programmes to induct in the PC, inspecting their validity and usefulness i.e. whether it suits the web purpose, just like a doctor examining some new implants into the body of a patient to verify if it has attuned to the whole set-up in perfect coordination.
As the doctor decides on the kind of inductions according to the patient needs, similarly the Application Programmers also write user-friendly programs in compliance with the customer needs. The programmes may be divided into general-purpose programs for a large and growing number of users or specific programs for individual use.
Application Programmers are truly the wizards of software operations. They are responsible for the entire running of the system as they are the ones who write, test programs, integrate them, evolve complex supporting documentation and maintain the detailed instructions, that computers must follow to perform their functions.
Application Programmers tell the computer what to do, such as which information to identify and access, how to process it, and what equipment to use. Conceiving, designing and revising the entire existing packaged software, from time to time are some of the foundamental tasks performed by them.
After the design process is complete, it is the job of the programmer to convert that design into a logical series of instructions that the computer can follow. Application Programmers then code these instructions in a conventional programming language, such as COBOL or one of the most advanced object-oriented languages such as Java, C++, or Smalltalk.
Different programming languages are used depending on the purpose of the program. Many Application Programmers update, repair, modify, and expand existing programs. For this purpose, they sometimes also use computer-assisted software engineering (CASE) tools to automate much of the coding process.
This also yields more reliable and consistent programs and increases programmers' productivity by eliminating some routine steps. Programmers test a program by running it, to ensure that the instructions are correct and it produces the desired information. If errors do occur, the programmer must make the appropriate change and recheck the program until it produces the correct results.
This process is called debugging. Application Programmers may continue to fix these problems throughout the life of a program. Application Programmers are often known as Computer Software Engineers, System Analysts, Computer Scientists, Database Administrator or Application Engineers
Tasks and Duties of an Application Programmers :
• Create Database tables
• Update, modify and maintain these tables
• Write simple SQL queries and embed them in an application program
• Optimize SQL queries
• Recognize Database objects and keywords
• Implement simple level security for Database tables
Depending on their interests, Application Programmers can specialize in:
a) Databases
b) Computer games
c) Operating systems
d) Networking
e) Graphical user interfaces
f) Financial applications.
Application programmers typically know multiple programming languages and have experience with multiple operating systems. They typically specialize in one of two broad categories of software:
1. Application Software is what most people are familiar with. Application software includes programs like computer games, MS Word, Quicken, Lotus 1-2-3, Oracle, and TurboTax.
2. System Software provides the interface between the computer hardware and software applications. Systems software includes device drivers, utilities, networking software, compilers, and operating systems such as MS Windows, MacOS, and Unix.
