Diagrams and charts are visual representations of information. They are useful for documenting facts, drawing plans, and capturing ideas and enhance communication, learning, and productivity.Taiwan mrt map
These visuals show relationships or connections between entities. Some show a directional flow of steps or information, as we see in flowcharts and network diagrams. Others display hierarchies, as in organizational charts and cause-and-effect diagrams. A Venn diagram is a chart-based diagram that illustrates the overlap among sets of data. These diagrams present statistical data graphically. The most common among these are the bar graphline graphhistogram, and pie chart.
An advantage of using graphs is that they can show changes over time or a comparison of numbers much more clearly than a data table can do. These types of diagrams show the elements in a system. Many schematic diagrams use standard symbol sets. They may be representational and drawn to scale, such as in a floor planwhere they must convey precise measurements and placement of elements.Name plates for workstations
Some schematics are more abstract, such as a circuit diagramin which the drawing shows the layout of a system, but not how it will actually appear in the physical circuit. SmartDraw helps you create over 70 different types of diagrams. Thousands of templates and powerful automation let you create diagrams as fast as typing a text document. Try it for yourself.

UML can be applied to diverse application domains e. It can be used with all major object and component software development methods and for various implementation platforms e.
UML is a standard modeling languagenot a software development process. UML 1. UML is intentionally process independent and could be applied in the context of different processes. Still, it is most suitable for use case driven, iterative and incremental development processes.
UML is not complete and it is not completely visual. Given some UML diagram, we can't be sure to understand depicted part or behavior of the system from the diagram alone. Some information could be intentionally omitted from the diagram, some information represented on the diagram could have different interpretations, and some concepts of UML have no graphical notation at all, so there is no way to depict those on diagrams.

For example, semantics of multiplicity of actors and multiplicity of use cases on use case diagrams is not defined precisely in the UML specification and could mean either concurrent or successive usage of use cases. Name of an abstract classifier is shown in italics while final classifier has no specific graphical notation, so there is no way to determine whether classifier is final or not from the diagram. Activity diagrams and sequence diagrams were enhanced.
Activities were redesigned to use a Petri-like semantics. Edges can now be contained in partitions. Partitions can be hierarchical and multidimensional. Explicitly modeled object flows are new. Classes have been extended with internal structures and ports composite structures. Information flows were added. A collaboration now is a kind of classifier, and can have any kind of behavioral descriptions associated.
Interactions are now contained within classifiers and not only within collaborations. It is now possible for use cases to be owned by classifiers in general and not just packages. New notation for concurrency and branching using combined fragments. Components can no longer be directly deployed to nodes. Artifacts should be deployed instead. Artifacts can now manifest any packageable element not just components, as before.
It is now possible to deploy to nodes with an internal structure. New metaclasses were added: connector, collaboration use, connector end, devicedeployment specification, execution environmentaccept event action, send object action, structural feature action, value pin, activity final, central buffer node, data stores, flow final, interruptible regions, loop nodes, parameter, portbehavior, behaviored classifier, duration, interval, time constraint, combined fragment, creation event, destruction event, execution event, interaction fragment, interaction use, receive signal event, send signal event, extension, etc.
Integration between structural and behavioral models was improved with better support for executable models. There are no longer two separate infrastructure and superstructure documents, the UML 2. Package merge is no longer used within the specification. UML 2.

Information flowsmodelsand templates are no longer auxiliary UML constructs. At the same time, use casesdeploymentsand the information flows became " supplementary concepts " in UML 2. They also moved and rephrased definition of qualifiers. There are few clarifications and fixes for stereotypes, state machines, and activities. Use cases are no longer required to express some needs of actors and to be initiated by an actor.
You can proceed to UML 2.For fast, easy-to-use piping and instrumentation diagram software, SmartDraw is the smart choice.

An entity relationship diagram is a specialized graphic that illustrates the relationships between entities in a database. ER Diagram software is an excellent communications tool, which can be used to confirm business requirements and provide direction to the architecture and design team as they move forward with physical database design rapidly. It's affordable and easy for illustrating the entity relationship diagrams by simply drag and drop.
Then add a connector among the entity relationship shapes, style and color that you want, An additional arrow style can be attached to the connector to illustrate the relationship between the different entities. Works on Mac OS X Edraw Max supports five types of entity relationship diagram. The different entity relationship diagram is using the different symbols to represent the relationships between entities in a database for most information management projects. But ER diagrams often use boxes to represent entities.
Diamonds are normally used to represent relationships and ovals are used to symbolize attributes. The following symbols of entity relationship diagram is based on the Chen ERD. Chen ERD uses rectangles to represent entities, and diamonds to represent relationships appropriate for first-class objects. If an entity set participates in a relationship set, they are connected with a line.
Attributes are drawn as ovals and are connected with a line to exactly one entity or relationship set. The following Martin ERD symbols is based on the symbols used in the Martin notation to draw object-oriented analysis and design diagrams.
Object Role Modeling is commonly used to describes the database of a model for information and rules analysis, ontological analysis, and data modeling in the field of software engineering: what objects may exist, what object classes they belong to, and what relationships exist between objects.Distribution waterfall model
The steps involved in creating an entity relationship diagram are:. When you create an entity relationship diagram, one of the first things that you should consider is the entities about which you wish to record information.
For example, in a family database, you probably wish to record information about member, house, job, love, contact, etc. However, in a relational database you record not only details about the entities but also the relationship between them. For example, in the family, members are assigned to house and every member is appointed to be in charge of each love and job. Entities are the "things" about which you wish to record information in a database.
There are relationships between entities which fall into three types: one-one, one-many, many-many. Any many-many relationship must be resolved into two one-many relationships. Examples of Entity Relationship Diagram.Ncis jack and faith
An entity relationship diagram example, showing a simple database for the business order process. The entity relationship diagram shown in the above image contains six entities - supplier, customer, order, item, product and shipment.
There are five kinds of relationship such as supplied by, requested on, used in, included on and sent by. In our example, every entity includes some attributes associated with each entity. In a real-world example, each one of these would likely have many different attributes.
