data-flow diagrams (DFDs) were introduced and popularized for structured analysis and design (Gane and Sarson 1979). DFDs show the flow of data from external entities into the system‚ showed how the data moved from one process to another‚ as well as its logical storage. Figure 1 presents an example of a DFD using the Gane and Sarson notation. There are only four symbols: Squares representing external entities‚ which are sources or destinations of data. Rounded rectangles representing processes

Describe at least two benefits of using enterprise systems. More and more organizations are seeking to integrate the core functions of their business with technological advances. Enterprise systems facilitate this integration process through a single software architecture that links all aspects of business to function as one unit. Enterprise systems also commonly known as ES are comprehensive‚ large scale application-software packages‚ which use powers of present day information

An ER diagram is a diagram containing entities or “items”‚ relationships among them‚ and attributes of the entities . The E-R model is one of the best known tools for logical database design. Within the database community‚ it is considered a natural and easy-to-understand way of conceptualizing the structure of database.

FISHBONE DIAGRAM The cause-and-effect diagram was initially developed by Japanese quality expert Professor Kaoru Ishikawa. In fact‚ these diagrams are often called Ishikawa diagrams; they are also called fishbone charts for reasons that will become obvious when we look at an example. Cause-and-effect diagrams are usually constructed by a quality team. For example‚ the team might consist of service designers‚ production workers‚ inspectors‚ supervisors‚ quality engineers‚ managers‚ sales representatives

Decomposition Diagram An analyst first must understand an organization’s business functions before he or she can begin developing information systems. The functional decomposition diagram (FDD) is a business planning tool that depicts the hierarchy of business functions‚ processes‚ and subprocesses within an organization that are later described in detail using process models (chapter 6). The exercise of breaking down‚ or decomposing‚ the business functions into processes makes complex systems much easier

What Benefits are Likely to Result from an Increasing use of Computers? A computer is a device that accepts information in the form of digitalized data and manipulates it for some result based on a program or sequence of instructionson how the data is to be processed . Modern computers inherently follow the ideas of the stored program laid out by John Von Neumann in 1945 . Essentially ‚ the program is read by the computer one instruction at a time ‚ an operation is performed and the computer then

Gear in Draw-works. Draw-works is the machine on the rig consisting of a large-diameter steel spool‚ brakes‚ a power source and assorted auxiliary devices. The primary function of the draw works is to reel out and reel in the drilling line‚ a large diameter wire rope‚ in a controlled fashion. The drilling line is reeled over the crown block and traveling block to gain mechanical advantage in a "block and tackle" or "pulley" fashion. This reeling out and in of the drilling line causes the traveling
