Input Controls
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 be data integrity errors that could occur and cause information to be incorrect in the database. There are advantages and disadvantages to restricting user interfaces to limit a person ability of typing in too much information or maybe not enough information.
Although there are many different types of input controls in this paper there will be only four of them that are addressed in this paper; this would include input mask, validation rules, source documents and batch input. First let’s talk about input mask. Input mask is an appearance that helps to characterize what type of contact is allowed in a given field on a template. The main purpose behind the input mask is to keep the data entry process somewhat the same and decrease the chances for incorrect data to be entered into the field. The input field entry can be configured to allow automatic field input as a way of saving time and resources. Input mask is created doing the process of computer programming. The fields on the template are recognized with specific control values. The values make it impossible to enter data that is not compatible with the values. An example of that would be when a field that contains an input mask that only allows letters will automatically reject the input of numbers and another one would be automatically converting the input into an adequate format an example of that would be when the input mask requires that the date field on the template specifies a format that is structured as
