Electronic Data Processing And Information Technology | most organizations Develop run their own applications software for the computers do have data processing departments These include all members of staff whose work is computer in the most cases, a mainframe based system business the rest of the staff of the organization are in one way or Other users of the computer system.
This “ traditional” arrangements of a separate data processing department is especially common in large organizations such as banks, insurance, companies, oil companies, many branches of national and state governments, and the armed forces.
Many smaller companies which make a extensive use of microcomputer and software packages
does not have data processing department instead they have computer units or information system division manned by a computer coordinator or network administrator. The computing environments is usually based on the network of microcomputers, the technical aspects of computer use are often shared by all the staff.
A Typical Data Processing Department
A staff chart of a typical data processing department is (DPD) given in the figure below, The department is headed by a data processing manager who is the key figure in the departments; he represent the department in outside matters within the organization he oversees the efficient functioning of the DPD in the light of the organization’s policy.
He should be a good administrator so as to be able to motivate staff he should have sound business knowledge, he should have knowledge and expertise in data processing, and he should have a long experience and relevant areas. This functions include budgeting, planning, coordination, personnel recruitment, and policy making.
The data processing (DPM) is responsible for the overall running of the data processing department. It is his or her responsibility to approve specific computing projects and ensure that the best use is made of the computing and data processing staff.
And that the department serve the best interest of the company. The data processing manager advises the Company Management on ways of adapting to new technology, and the implications for the company. The data processing is usually in charge of staff appointment. Within, the department.

The Chief system analyst, the chief programmer, and the operations manager or reports directly to the data processing manager. The operations manager may report to the Director of Information Processing or an appropriate head of functional unit, who reports to the chief executive of the organization.
Computer System analyst
System analyst is concerned with planning how work is done on the computer. When a new area of work is to be computerized. The consults with the potential users of the computer and study the existing operation in details.
They then submit a plan of the computerized version of the work, which contains the description of each step, both on and off the computer. The description. Normally includes system flow diagram which illustrates each stage.
The plan is then modified. After discussion with the users and various managers involved system analyst have normally built up their computing experience as programmers, and they have been trained in the system analysis.
- Employees generally prefer applicants who have at least a bachelor’s degree in computer science, information science, or Management Information Science.(MIS)
- Employment is expected to increase much faster than the average, and more new jobs are expected to arise. Than, In all but , a few other
- very good job prospects are expected as organizations, continue to adopt increasingly sophisticated technologies.
Nature of the work
all organizations rely on Computer and Information Technology to conduct business, and operate efficiently . computer system analysis help organization to use technology effectively, and to incorporate rapidly changing technologies into their existing systems.
The work of computer system analyst evolve rapidly, reflecting new areas of specialization and changes in technologies.
Computer system analyst solve computer problems, and use computer technology to meet the needs of an organization. They may design to develop new computer system by choosing and configuring hardware and software.
They may also devise with to apply existing system resources and additional tasks.
Most system analyst work within specific types of computer systems, for example, business accounting or financial systems or scientist and engineering systems that varies with the kind of organization analyst who specialize in helping an organization.
Select it a proper system software and infrastructure, often called system. Architects. Analysis, who specialized in developing and fine tuning systems often known as see them designers.
To begin, and assignments. systems analyst consults managers and users to define the goals of the system, analyst, then design a system to meet those goals. They specified the input that the system will access. Decide how the inputs, will be processed and formats.
The output to meet users needs. Analysts use techniques, such as Structured Analysis data modeling information.
Engineering mathematical model building, sampling, and cost accounting, to make sure the plans are efficient and complete the also may prepare cost benefits and return on investment analysis to help management, decide whether implementing the proposed technology would be financially feasible.
When a system is approved, system analysis, determine what computer hardware and software that will be needed to set it up, the coordinate tests and observe the initial use of the system to ensure that each perform as planned
.They prepare specifications, flow charts and process diagrams for computer programmers to follow.
Then they work with programmers to debug or eliminate errors from the system. System analyst who do more in depth testing, maybe called software quality assurance analysts.
In addition , to running. Tests These workers diagnose problems. Recommend, solution, and determine whether program requirements, have be met.In some organizations programmers, analysts design and update the software that runs a computer.
They also create custom application, tailored to their organization’s tasks, because they are responsible for boths programing and system analysis.
These workers must be proficient in both areas,( A separate section on computer programmers appears elsewhere in the handbook.).As this dual proficiency becomes more common analysis. increasingly working with database object oriented programming languages, client-server applications and multimedia and internet technology.
