TEN RELATED HOW TO's:
This method of problem analysis is widely used in IT, manufacture industries and chemical engineering. If you want to take a fresh look on your problem, you can draw a fishbone diagram with ConceptDraw DIAGRAM software, which supports both MAC OS and Windows. You can see and download fishbone diagram samples and templates in ConceptDraw Solution Park.
This Fishbone (Ishikawa) diagram can be applied as template for performing the cause and effect analysis of a service industry problems. It can help to determine factors causing problems. Causes in this diagram are categorized according to the 4S’s principle that means Surroundings, Suppliers, Systems and Skills. Grouping causes allows to reveal main interactions between different events. This diagram was made using ConceptDraw Fishbone diagrams solution. It can help to reveal the causes effected a complicated issue. Of course it can be used together with other methods of approaching to the problem solving.

It is very difficult to get into database model idea without any examples. To create one, you can use Chen’s notation for Entity Relationship Diagrams (ERD) and try to see all the peculiarities yourself. This notation describes entities and relations as basic geometric shapes like rectangles and diamonds.
Chen notation for Entity-relationship diagrams is used for designing relational databases. It depicts the database entities as a set of subjects. For example events, people, ideas, etc. All entities has common characteristics (attributes). Any object of the system is identified as the sole and unique. The name of entity should indicate the class or type of the the whole object, not a given example. The connection commonly represents a relationship between entities. Conceptdraw Entity-Relationship Diagrams (ERD) solution provides the libraries with ready-to-use ERD element fitting Chen's notation objects and relationships.

The entity–relationship (ER) model is a data model that lets graphically represent the information system and depict the relationships between people, objects, concepts, places, and events within a given system. It is also convenient to use the ER Diagram for Cloud computing representation and description the Cloud computing architecture, design them with pleasure using the extensive tools of the Cloud Computing Diagrams solution from the Computers and Network area of ConceptDraw Solution Park.

A database is a data collection, structured into some conceptual model. Two most common approaches of developing data models are UML diagrams and ER-model diagrams. There are several notations of entity-relationship diagram symbols and their meaning is slightly different. Crow’s Foot notation is quite descriptive and easy to understand, meanwhile, the Chen notation is great for conceptual modeling.
An entity relationship diagrams look very simple to a flowcharts. The main difference is the symbols provided by specific ERD notations. There are several models applied in entity-relationship diagrams: conceptual, logical and physical. Creating an entity relationship diagram requires using a specific notation. There are five main components of common ERD notations: Entities, Actions, Attributes, Cardinality and Connections. The two of notations most widely used for creating ERD are Chen notation and Crow foot notation. By the way, the Crow foot notation originates from the Chen notation - it is an adapted version of the Chen notation.

The first thing that usually comes to mind when talking about database models is ER-diagrams, and the ways to create them. The second most recognizable notation is the Crow’s Foot, which visually differs from Chen’s notation. Actually, it doesn’t matter which notation you’ll use for your entity relationship diagram (ERD), but the content is what matters.
When designing an Entity-Relationship Diagram one need to use a certain notated symbols that were developed and standardized especially for databases description. First of them - the Chen’s notation had a linguistic origin. It includes rectangle boxes to show entities that may be described as nouns, and the relationships between them described as verbs depicted in a form of diamond. Finally the Chen’s notation was simplified up to the Crow’s Foot notation. It represents a relationship as labeled line. It is precisely this notation is shown in the given figure. ConceptDraw DIAGRAM together with its Entity-Relationship Diagram (ERD) solution is designed to support professionals who deals with creating ER diagrams using the element of both - Chen’s and Crow's Foot notations.
