------------------------------------------------- Methodological Basis of CDSS There are many different methodologies that can be used by a CDSS in order to provide support to the health care professional.[8] The basic components of a CDSS include a dynamic (medical) knowledge base and an inferencing mechanism (usually a set of rules derived from the experts and evidence-based medicine) and implemented through medical logic modules based on a language such as Arden syntax. It could be based on Expert

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

Assignment: Draw and explain a Use-Case diagram for a Library Management System. Introduction: Capturing the dynamic behaviour of a system is one the key aspects to create a model. Dynamic behaviour means the behaviour of the system under operation. Use case diagrams are used in Unified Modeling Language‚ a standard modelling language for the modeling of real-world objects and systems. A use case diagram is to explicitly define the working of a system with in a system boundary. Each system is primarily

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

Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation. A free-body diagram is a special example of the vector diagrams that were discussed in an earlier unit. These diagrams will be used throughout our study of physics. The size of the arrow in a free-body diagram reflects the magnitude of the force. The direction of the arrow shows the direction that the force is acting. Each force arrow in the diagram is labeled

Using Data Flow Diagrams Data flow diagram is used by system analyst to put together a graphical representation of data processes throughout the organization. It depicts the broadest possible overview of system inputs‚ processes‚ and outputs. A series of layered data flow diagrams may be used to represent and analyze detailed procedures in the larger system. By using combinations of only four symbols‚ the system analyst can create a pictorial depiction of processes that will eventually provide
