...his personal interviews with cash receipts clerks, Ashton asks you to develop a comprehensive DFD for the cash receipts system. Ashton’s narrative of the system follows: Customer payments include cash received at the time of purchase and account payments received in the mail. At day’s end, the treasurer endorses all checks and prepares a deposit slip for the checks and the cash. A clerk then deposits the checks, cash, and a deposit slip at the local bank each day. When checks are received as payment for accounts due, a remittance slip is included with the payment. The remittance slips are used to update the accounts receivable file at the end of the day. The remittance slips are stored in a file drawer by date. Every week, a cash receipts report and an aged trial balance are generated from the data in the accounts receivable ledger. The cash receipts report is sent to management. A copy of the aged trial balance by customer account is sent to the credit and collections deportment. Shown below are a context and level 0 DFD for the system. Context Diagram Level 0 DFD 1. Using the information above, prepare a document flowchart to document the cash receipts system at S & S.

...E-R Diagram E-R Diagram Entity-Relationship Diagram is a graphical representation of entities and their relationship to each others. It describes how data is related to each other. An entity is a piece of data- an object or a concept about which data is stored. A relationship is how the data is shared between entities. In E-R Diagram, there are 3 main Components: E-R Diagram of a Hospital Management System Data Flow Diagram A Data Flow Diagram (DFD) is a graphical representation of the "flow" of data through an information system, modeling its process aspects. DFD is often used as a preliminary step to create an overview of the system, which can later be elaborated. The purpose of data flow diagrams is to provide a semantic bridge between users and systems developers. The diagrams are: * graphical, eliminating thousands of words; * logical representations, modeling WHAT a system does, rather than physical models showing HOW it does it; * hierarchical, showing systems at any level of detail; and * jargonless, allowing user understanding and reviewing. The goal of data flow diagramming is to have a commonly understood model of a system. The diagrams are the basis of structured systems analysis. Data flow diagrams have the objective of avoiding the cost of: * user/developer misunderstanding of a system, resulting in a need to redo systems or in not using the system. * having to start documentation from scratch when the physical system changes...

...Describe the Gane and Sarson symbols used for processes, data flows, data stores, and entities. Give four examples of typical names for processes, data flows, data stores, and entities. http://www.softtester.org/portfolio/cis244/assignment8.html 3. What is the relationship between a Context Diagram and Diagram 0, and which symbol is not used in a context diagram? A context diagram is a top-level view of an information system that shows the boundaries and scope of the system, whereas a diagram 0 is a DFD that depicts the first level of detail below the initial context diagram and shows major processes, data flows and data stores as well as repeating the external entities and data flows that appear in the context diagram. Data stores are not shown in the context diagram because they are contained within the system and remain hidden until more detailed diagrams are created. (https://ict108businessinformatics.wikispaces.com/Questions+Week+5) 4. What is meant by an exploded DFD? An exploded DFD has a higher-level diagram called the parent diagram, and a lower-level diagram that is referred to as the child diagram. In this sense, a diagram 0 is a child diagram of a context diagram because diagram 0 is a more detailed or...

...SOFTWARE REQUIREMENT SPECIFICATION A Software Requirements Specification (SRS) - a requirements specification for a software system - is a complete description of the behavior of a system to be developed. It includes a set of use cases that describe all the interactions the users will have with the software. Use cases are also known as functional requirements. In addition to use cases, the SRS also contains non-functional (or supplementary) requirements. Non-functional requirements are requirements which impose constraints on the design or implementation (such as performance engineering requirements, quality standards, or design constraints).

A Context Diagram in the field of software engineering and systems engineering is a diagram that defines the boundary between the system, part of a system and its surroundings, which shows the entities that interact with it. This diagram is a high level view of a system. System context diagrams show a system, often software-based, as a whole and its inputs and outputs from/to external factors (Kossiakoff and Sweet 2011). Context diagram represents all external entities that can interact with the system. Context diagrams describe the system in the center, with no details of the structure of its interior...

...Solutions Manual to accompany Accounting Information Systems 4e Brett Considine, Alison Parkes, Karin Olesen, Yvette Blount & Derek Speer by Alison Parkes John Wiley & Sons Australia, Ltd 2013 Chapter 9: Transaction cycle – the revenue cycle Discussion Questions 9.1 Brisbane Ltd has always had a strategy of product differentiation; that is, providing high quality products and extracting a price premium from the market. During the recent economic downturn, Brisbane Ltd has seen its customer base diminish and has decided to move strategically to a cost leadership strategy, that is, to try to sell more products at a lower price. (a) What are the implications of this strategy change for the revenue cycle? (LO1). This strategy change will have big implications for the revenue cycle, which is fundamentally driven by the level of sales. All existing policies and procedures will be geared around volume, pricing and quality targets flowing from the product differentiation (high price / high quality) strategy. To move to a cost leadership (high volume / low price) strategy requires revisiting and realigning existing policies and procedures. (b) What changes would you expect to see in the revenue cycle? (LO4). Assessing changes in the order of the processes in the revenue cycle: 1.1 The inventory check would be performed as described however the policy relating to tolerances on inventory decisions may alter, allowing Brisbane Ltd to...

...ABSTRACT The aim of this study is to design a computerized voting system based upon the electoral process adopted in Pamantasan ng Lungsod ng Maynila. In recent years, information technology has greatly affected all aspects of life, and to a large extent, this includes politics. In order to choose people to various positions different methods have been set up, with researchers continually trying to find improvement to the existing methods. The most recent method to be devised is electronic voting (e-voting). It is meant to phase out outdated paper ballot, punched cards and other mechanical voting systems with paperless electronic or online voting systems. Computerized voting systems endeavour to make elections simple while reducing the total cost of the election. Designing an air-tight and reliable computerized voting system is therefore a great task, in that, the system that must be developed must protect the privacy of the voter, be easily understood and used by the entire voting populace - no matter who they are or where they come from.

...superior to the commonly used Structured Analysis (SA) modeling tools of flowcharts (FC), data flow diagrams (DFD), and entity-relationship diagrams (ERD). Dr. White suggests that using UML diagrams as a tool to document AIS is a viable alternative to the Structured Analysis’s diagrams of FC, DFD, and ERD. What follows in Section II is a brief comparison of the two alternative approaches to systems documentation: Structured Analysis (SA) and Object Orientation (OO). Section III presents the definition and description of the major structural and behavioral elements used in UML including classifiers, instances, relationships, collaborations, activities, interactions, and states. Section IV discusses the organization and presentation of UML documentation of AIS as a collection of diagrams and packages. Section V contains various UML diagrams of the business revenue cycle (system) as examples of how to use UML to document a business system. Section VI contains examples of UML models of two special systems of great importance to accountants: the General Ledger system with an AJE component, and the AIS Internal Control system. Appendix 1 contains a UML glossary of italicized words found in this IDoc. II. TWO APPROACHES TO AIS ANALYSIS & DOCUMENTATION Structured Analysis (SA) Traditionally, the modeling of AIS has used three disparate types of system diagrams: (1) the flowchart (FC), (2) the data flow diagram (DFD), and (3)...
