Concept explainers

Design of user interface

The complete process of designing the user interfaces in software or the various digital devices with an emphasis on the appearance or style is known as user interface (UI) design. The User interface (UI) design is defined as the technique that is used by the designers to produce visually pleasant software or digital device interfaces. The designers just strive to design user interfaces that are simple to use and are enjoyable to use. Graphic user interfaces and other sorts of user interfaces, such as voice-controlled interfaces, are referred to as UI design. The user interface design anticipates what users will do and incorporates elements that make those actions easy to access, understand, and utilize. The user interface includes interaction design, visual design, and information arrangement.

Learning Objective PI3.2 Understand the process of entity-relationship modeling. STEP 1: Background It is very important that you understand the connections among entities, attributes, and relationships. This section has defined each of these terms for you. Typically, entities are described by their attributes, and they are related to other entities. For example, if "student name" is the entity, then age, gender, country of origin, marital status, and other demographic data are the attributes (characteristics) of that particular student. That student is also related to other entities such as financial information, major, and course information. STEP 2: Activity An entity-relationship model is one of the most challenging aspects of designing a database because you have to (1) understand the rules that govern how processes work and (2) be able to define and describe these rules in a picture. This section has provided you with the necessary tools to draw a basic ER model. Imagine the…
