Entity-Relationship Diagrams (ERD) Data models are tools used in analysis to describe the data requirements and assumptions in the system from a top-down perspective. They also set the stage for the design of databases later on in the SDLC. There are three basic elements in ER models: Entities are the "things" about which we seek information. Attributes are the data we collect about the entities. Relationships provide the structure needed to draw information from multiple entities. Generally

RAW: _______ /63 pts 1. Explain the operation of an encoder. (1 point) ________A device that converts a weighted numeric input line to an equivalent digital code‚ such as hex or octal.____________________________ 2. What does it mean when an encoder is a priority encoder? (1 point) _________The method used to handle multiple key closures. This means that logic establishes a rank order for the keys so that a key closure of lower priority will not change encoding of a higher priority key._______________________

New Er Digram for BIOIn software engineering‚ an entity–relationship model (ER model) is a data model for describing the data or information aspects of a business domain or its process requirements‚ in an abstract way that lends itself to ultimately being implemented in a database such as a relational database. The main components of ER models are entities (things) and the relationships that can exist among them. Entity-relationship modeling was developed by Peter Chen and published in a 1976 paper

Week 1-Discussion 1-Circular Flow Diagram To first explain how the circular flow diagram relates to the current economic situation‚ one must realize that the two‚ three‚ and four sector models no longer apply to the United States any more. Only the five sector model currently applies. The five sector model of the circular flow of income is a more realistic representation of the economy and has a more definitive look as to what and how economics really is in the world. In the more simplistic two

The Power On Self Test When the system is powered on‚ the BIOS will perform diagnostics and initialize system components‚ including the video system. (This is self-evident when the screen first flicks before the Video Card header is displayed). This is commonly referred as POST (Power-On Self Test). Afterwards‚ the computer will proceed its final boot-up stage by calling the operating system. Just before that‚ the user may interrupt to have access to SETUP. To allow the user to alter the CMOS
