Input Control Jamie Robinson Professor Mohammed CIS 210 August 11‚ 2012 Input Control Input controls are fail safes that ensure that data is entered correctly‚ completely‚ and securely‚ in order to complete forms. As a systems analyst‚ one must focus on input control in every step of input design. There are many types of input control that can be implemented during the design process; all of which have a function necessary to maintain the integrity of the transaction. To list all of the

The objective of input design is to ensure the quality‚ accuracy‚ completeness‚ and timeliness of input data during its conversion from its original source into computer data‚ or entry into a computer application. Data can be entered into a computer application from either manual online input or by scheduled automated processing. Input controls will ensure that data is accurately processed through the application and that no data is added‚ lost‚ or altered during processing (Shu‚ unk). No matter

INPUT CONTROLS CIS210 May 13‚ 2012 ABSTRACT This paper will look at several different input controls‚ what their roles and purposes are and explain the function of each. It will provide examples of what types of data integrity errors could occur if each of the types of controls were not in place and lastly‚ it will discuss the advantages and disadvantages of restricting user interfaces. DIFFERENT INPUTS When data needs to be entered into a system‚ there are various ways to accomplish

Input Controls Raymond Chandler Professor Chad Frommeyer CIS210036VA016-1142-001 (Systems Analysis And Development) 02/11/2014 Input controls are an integral part of a user interface (UI)‚ which enable the user to interact with a software program and its data. Input control includes the necessary measures to ensure that input data is correct‚ complete and secure (Rosenblatt & Shelly‚ 2012). There are many types of input controls that can be used in various applications

Input Controls When we talk about input controls‚ what are we really talking about? Input control includes the necessary measures to ensure that data is correct‚ complete‚ and secure. A system analyst must focus on input control during every phrase of input design‚ starting with source documents that promote data accuracy and quality. (Shelly & Rosenblatt‚ (2012)). Input controls can help the flow of data in a database to be the same format and easy to understand. Without input controls there can

MOPO - OutCome 1: Case Study 1) A goal is a long term target. Requires around 1 – 5+ years of work and is often not specific enough to be measured. It is achieved by completing numerous ‘objectives’ within its framework. Goals are set by top level teams of businesses. They are intentions. An objective is a short/mid term target that is more specific and can be measured. They take around 1 – 12 months to complete. Objectives are created by mid and lower level parts of a business‚ they are made
