Review Questions

Define detail reports, exception reports, and summary reports. Explain the concept of a control field and how it is used to produce a control-break report.

- A detail report produces at least one line of output for every record processed. In an exception report, only those records that satisfy a specific condition are reported.

- A summary report displays only subtotals and totals.

- A control field is a field that controls the output by determining its sequence and defining a control break.

- A control break occurs when the value of a control field changes. It uses one or more control fields and generates some type of special output, such as printed subtotals or totals, at control break points.

Explain the concept of human-computer interaction (HCI). Why is this important? How does it impact the work of the systems analyst?

New System Design

...Introduction I have written this proposal to offer a new system design for our invoicing process. Recently we switched to a new filing system for invoices. We used to keep all paper invoices and file them according to customer. At the end of the year, we pulled all the invoices, filed them into boxes, and moved them into storage. This system was very inefficient, so we decided to start scanning the invoices and corresponding documents and saving them to the server in a specific folder for invoices. Although we have benefitted greatly from no longer keeping paper invoices, we are still much disorganized, and we waste a great deal of time searching for invoices. Customers will often call asking for a proof of delivery after we have already sent the invoice, but they have not yet received it. When this happens, we need to search through a file with often more than 50 invoices, and then send the customer a copy. Many customers would rather wait on hold or wait with you on the phone while you search for the file, instead of having you call them back. This process can take anywhere from 5 to 8 minutes, while the customer sits waiting on the phone. We go through this same process when a customer calls with a question on an invoice they have received. Customers sometimes get very agitated when you cannot find the information right away. There are also instances when our server is down and we cannot access information stored on the server, which is where the...

System Analysis and Design

... into a single, integrated information system. APPROACHES TO ANAYSIS AND DESIGN A Framework for Analysis and Design Methods The framework we’ve adopted identifies three distinct categories of systems model that can be found in a development method. These categories of model are de.ned as • the business system model; • the data structure model; • the dynamic behaviour model. This framework for analysis and design methods can be mapped onto some of the earliest approaches to systems development. These early methods were extended in the 1970s with the development of structured methods, and the framework usefully classifies the models used in this approach. The framework is also applied to the object-oriented approach with a degree of success. Other approaches described in the text .t less well, and from this we are able to suggest their suitability for particular types of application development. Developers in the 1960s placed a heavy emphasis on programming skills, and logic or flowcharts were one of the principal planning tools in application development. As applications became more complex, and management information systems demanded greater and greater amounts of systems integration, the need for a higher level of systems planning was identified. This led to the first analysis and design method to be formally de.ned, being known as the NCC (National Computing Centre) method. The principle models or techniques in this approach were: • The systems .Flowchart...

... by John Papproth You can script anything! Page 5 of 16 The WScript object allows you to:  create objects,  connect to objects,  disconnect from objects,  sync events,  stop a script's execution programmatically,  output information to the default output device (either a Windows dialog box or the command console). You create a WshShell object whenever you want to run a program locally, manipulate the contents of the registry, create a shortcut, or access a system folder. The WshShell object provides the Environment collection. This collection allows you to handle environmental variables (such as WINDIR, PATH, or PROMPT). You create a WshNetwork object when you want to connect to network shares and network printers, disconnect from network shares and network printers, map or remove network shares, or access information about a user on the network. The FileSystemObject is used to provide access to a computer’s file system. Limited Input and Output to the Window’s Desktop – Inputbox, Msgbox, and wshShell.PopUp: For returning input text from the user, VBSCRIPT provides an INPUTBOX function that accepts three string values as input parameters: a prompt, a title for the window caption, and a default value. If the OK button is clicked, the value entered by the user is returned as a string. If the CANCEL button is clicked a zero length string is returned.

Accounting System Analysis & Design

...BKAS3063 ACCOUNTING SYSTEM ANALYSIS & DESIGN ANSWER FOR TUTORIAL 3 There are several methods that systems analysts use to determine requirements for a proposed system. The requirements gathering techniques can be categorized into traditional, modern, or radical. The traditional requirements gathering techniques are interviews, questionnaires, , and documents analysis. The modern requirements determination techniques include Joint Application Design (JAD), group support systems, prototyping, and CASE tools. Business Process Reengineering (BPR) is a radical method for determining system requirements. Each of these approaches has advantages and disadvantages to system implementation and operation. 1. Briefly describe systems analysis and the major activities that occur during this phase of the systems development life cycle. (4 Marks) Answer: Systems analysis involves determining how the current information system functions and assess what users would like to see in a new system. Requirements determination, requirements structuring, and alternative generation and selection are the three primary systems analysis activities. 2. Describe THREE (3) traditional techniques for collecting information during analysis. When might one be better than another?

...Tasks 1. Jesse wants me to recommend a vendor who offers an ERP strategy. I need to review the SAP and Oracle Web sites, and at least two others that offer ERP solutions, and reply to her with the results and the reasons for my recommendations. After further review and research on the different ERP vendors, my recommendation is to choose SAP because of following reasons: • Scalability • Reliability • Wide range of services offered • Reputation in the market • More built in practices Even though the cost is a little higher, SAP still is the first choice of businesses. 2. Visit SCR's data library to review SCR's network configuration and then send Jesse a recommendation for the TIMS system architecture. She wants me to suggest an overall client/server design, number of tiers, and network topology. She also asked me to comment on these issues: legacy data, Web-centricity, scalability, security, and batch processing that might be needed. Jesse said it was OK to make reasonable assumptions in my proposal to her. I would suggest two-tier client-server architecture for TIMS because it meets the demands of TIMS.I really think that a star topology will support the network requirements of TIMS with a switch, server, and connected laptops and workstations. SCR is a new company and they don’t have that much data in its TIMS record so legacy systems are not required and if there is any old outdated data that needs to be converted or transferred because of less...

...3.1 Design of the whole system As mentioned before, safety issue in sharing economy has arouse public’s concern, as robberies or rap cases are reported by media one after another. Because of this, we hope to design a safety system that are able to protect both service providers and receivers’ safety to the greatest extent during the entire service process. In the following, we will take Uber as an example to introduce in detail how this system works in different stages. 3.1.1 Registration When users register an account, they are required to fill in basic personal information and set one or more contact persons. Information integrity contributes to investigation on condition that incident unfortunately happens. Contact person chosen by users can share the users’ location and will receive warning once the users encounter dangers during the service process. Besides, since in most cases, it is service receivers who encounter dangers, service providers will be asked to uploading their police certificate and complete real-name identity authentication by uploading their ID card when register in order to ensure that these providers are credible and reliable 3.1.2 Ride process Passengers A.
