FIGURE DEFINITION
A Gantt chart is a graphical representation of the duration of tasks against the progression of time. This kind of chart is a useful tool for planning and scheduling project.

Symbols
| Gantt bars indicate the duration of tasks. |
| Milestone markers signal a major turning point in the project such an approval meeting or the release of a product. They can also mark the beginning and end of tasks. | | Links lines show the relationship between two tasks, often indicating that a task can only begin when another ends. |

Data Flow Diagram (DFD) is an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations. DFDs reveal relationships among and between the various components in a program or system. Symbols

External Entities – Squares representing external entities, which are sources or destinations of data.

Process – Squares representing external entities, which are sources or destinations of data.

Data Store – This is symbol used for depository data that allows addition and retrieval of data.

Data Flow –which can either be electronic data or physical items?

 An entity-relationship (ER) diagram is a specialized graphic that illustrates the relationships between entities in a database.
Symbols
Entities the "things" about which we seek information.

Relationship provides the structure needed to draw information from multiple entities.

Attribute the data we collect about the entities.

Exactly-one represents exactly one relationship.

One-to-more represent one is to many relationships.

Greater-than-one represents to more than one relationship.

Zero-to-many used to join zero to many relationship.

A system flowchart is a concrete, physical model that document, in an easily visualized, graphical form, the system’s discrete physical components (its programs, procedures, files, reports, screens, etc.).

Symbols
It is not strictly necessary to use boxes, circles, diamonds or other such symbols to construct a flowchart, but these do help to describe the types of events in the chart more clearly. Described below are a set of standard symbols which are applicable to most situations without being overly complex.

Rounded Box –used to represent an event which occurs automatically. Such an event will trigger a subsequent action, for example `receive telephone call', or describe a new state of affairs.
Box or Rectangle –used to represents an event which is controlled within the process. Typically this will be a step or action which is taken. In most flowcharts this will be the most frequently used symbol.

Diamond –used to represents a decision point in the process. Typically, the statement in the symbol will require a `yes' or `no' response and branch to different parts of the flowchart accordingly.

Circle (Connector) – used to represent a point at which the flowchart connects with another process. The name or reference for the other process should appear within the symbol.

Off Page Connector–This shape means the flow continues on another page. A letter or page number in the shape tells you were to go. It is an alternative to using a circle.

Terminator - This shape tells you where the flowchart begins and ends. It shows the entry point of your flowchart and the exit point. To designate the start of your flowchart, you would fill this shape with words like Start or Begin.

Input/output– A parallelogram is used to show input or output. Examples of input are receiving a report, getting an e-mail, getting an order, receiving data in some...
