E-R Diagram Introduction:- In 1976 ‚Chen developed the Entity-Relationship Diagrams ‚a high-level data model that is useful in developing a conceptual design for database . An ER diagram is a diagram containing entities or “items”‚ relationships among them‚ and attributes of the entities . The E-R model is one of the best known tools for logical database design. Within the database community‚ it is considered a natural and easy-to-understand way of conceptualizing the structure of database.

Dependencies and Network Diagram The network diagram is a schematic representation showing the sequence and relationship/ dependency of the tasks along with their duration. All the tasks‚ except the first and the last‚ are linked with at least one predecessor and successor to have a proper sequence of work. This logical dependency between the tasks will determine afterwards the duration of the project. There are four types of dependencies which define the relation between pair tasks Finish-to-start

Component Diagram Notations The component diagram’s main purpose is to show the structural relationships between the components of a system. In addition‚ component diagrams are useful communication tools for various groups. In creating a component diagram‚ there are different notations that can be used to show the different relationship of each component within the system. The component diagram notation set now makes it one of the easiest UML diagrams to draw: * COMPONENT A component can

AnalasysiPROCESS ANALYSIS WRITING Firstly‚ Process or processing typically describes the action of taking something through an established and usually routine set of procedures or steps to convert it from one form to another‚ such as processing paperwork to grant a mortgage loan‚ processing milk into cheese‚ or converting computer data from one form to another. A process involves steps and decisions in the way work is accomplished‚ and may involve a sequence of events. The source of this information

Lynnzie Tompkins December 6‚ 2014 Dr. Jutila Flow Cytometry (BIOB413) A look into Flow Cytometry Flow cytometry is a widely used practice in the biotechnology field; it is mainly used routinely for the diagnosis of health disorders. However‚ flow cytometry is also commonly used‚ as an application for basic research. Simply‚ flow cytometers are automated machines that determine properties of individual cells (e.g. cell size‚ cell granularity‚ and total DNA). Cytometers are similar to microscopes

greek words: cyto- cell‚ and metry - measurement. So cyto-metry is about making cell measurements. To elaborate‚ flow cytometry is a technique for analysing particles (cells in this case) which are suspended in a fluid stream by flowing the cells past an interrogation point. A light source is directed on to a hydrodynamically focused stream to create a zone for interrogation. As cells flow through this interrogation zone they scatter the light‚ at this point any fluorescent compounds that are inside
