tape to manager Storage: sales file (register tape)‚ cash register 3.2 It is usually not sufficient to use just one documentation tool. Every tool documents a uniquely important aspect of a given information system. For example‚ system flowcharts are employed to understand physical system activities including inputs‚ outputs‚ and processing. In contrast‚ data flow diagrams provide a graphic picture of the logical flow of data within an organization. Each alternative is appropriate for

Data Processing Data Processing is the term generally used to describe what was done by large mainframe computers from the late 1940’s until the early 1980’s (and which continues to be done in most large organizations to a greater or lesser extent even today): large volumes of raw transaction data fed into programs that update a master file‚ with fixed-format reports written to paper. Number System A numeral system (or system of numeration) is a writing system for expressing numbers‚ that is

Flowchart for a Process Paper Operations Management 571 August 28‚ 2010 Flowchart Process There are multiple processes that we do in our daily lives that we would like to take a short amount of time to complete it. "A process is any part of an organization that takes inputs and transforms them into outputs that‚ it is hoped‚ are of greater value to the organization than the original inputs" (Chase‚ Jacobs‚ Aquilano‚ 2006‚ p. 154). Flowcharts are easy-to-understand by demonstrating step-by-step

ETHERS Classification of Ethers: Symmetrical ethers – two groups attached to O are identical Ex. CH3CH2OCH2CH3 – diethyl ether Unsymmetrical ethers – two groups attached to O are not identical Ex. CH3CH2OCH3 – ethyl methyl ether Physical Properties of Ethers: Ethers have much lower boiling points compared to alcohols of comparable MWs. BPs of ethers increases with increasing MW. BPs of isomeric ethers increase with increasing alkyl chain length. BPs of ethers are about the

Programming Logic and Design‚ 6th Edition Chapter 4 Exercises 2. Chocolate Delights Candy Company manufactures several types of candy. Design a flowchart or pseudocode for the following: a. A program that accepts a candy name (for example‚ “chocolate-covered blueberries”)‚ price per pound‚ and number of pounds sold in the average month‚ and displays the item’s data only if it is a best-selling item. Best-selling items are those that sell more than 2‚000 pounds per month. Answer:

(written descriptions) Flowcharts Diagrams Other written material For this subject‚ we only need to discuss two (2) of the most common documentation tools: Data flow diagrams Graphical descriptions of the sources and destinations of data. They show: Where data comes from How it flows The processes performed on it Where it goes Include three types: Document flowcharts describe the flow of documents and information between departments or units. System flowcharts describe the relationship

How can you declare global and local variables in flowcharts? • Global variables are displayed in pseudo code but not in flowcharts directly o In order to declare global variables in a flowchart‚ you’d put that variable in the main part of the program (the main box where other functions will branch off from) for local variables‚ you’d put
