Informatica ETL Developer Overview

Software developers are the creative minds behind computer programs. Some develop the applications that allow people to do specific tasks on a computer or another device. Others develop the underlying systems that run the devices or that control networks.

Software developers typically do the following:

• Analyze users’ needs and then design, test, and develop software to meet those needs
• Recommend software upgrades for customers’ existing programs and systems
• Design each piece of an application or a system and plan how the pieces will work together
• Create a variety of models and diagrams (such as flowcharts) that instruct programmers how to write software code
• Ensure that a program continues to function normally through software maintenance and testing
• Document every aspect of an application or a system as a reference for future maintenance and upgrades
• Collaborate with other computer specialists to create optimum software

Software developers are in charge of the entire development process for a software program. They may begin by asking how the customer plans to use the software. They must identify the core functionality that users need from software programs. Software developers must also determine user requirements that are unrelated to the functionality of software, such as the level of security and performance needs. They design the program and then give instructions to programmers, who write computer code and test it.

If the program does not work as expected or if testers find it too difficult to use, software developers go back to the design process to fix the problems or improve the program. After the program is released to the customer, a developer may perform upgrades and maintenance.

Developers usually work closely with computer programmers. However, in some companies, developers write code themselves instead of giving instructions to the programmers.

Developers who supervise a software project from the planning stages through implementation sometimes are called information technology (IT) project managers. These workers monitor the project’s progress to ensure that it meets deadlines, standards, and cost targets. IT project managers who plan and direct an organization’s IT department or IT policies are included in the profile on computer and information systems managers.

The following are examples of types of software developers:

Applications software developers design computer applications, such as word processors and games, for consumers. They may create custom software for a specific customer or commercial software to be sold to the general public. Some applications software developers create complex databases for organizations. They also create programs that people use over the Internet and within a company’s intranet.

Systems software developers create the systems that keep computers functioning properly. These could be operating systems for computers that the general public buys or systems built specifically for an organization. Often, systems software developers also build the system’s interface, which is what allows users to interact with the computer. Systems software developers are creating the operating systems that control most of the consumer electronics in use today, including the systems in phones or cars.
