Entity Relationship Diagram - ERD - Software for Design Crows Foot ER Diagrams

There are many ways to describe a database structure. One of the most usual is to draw an entity relationship diagram (ERD) using a Crow’s Foot notation to represent database elements. If you don’t want to draw it on paper, you should use an appropriate software. An entity-relationship (ER) diagram is used to show the structure of a business database. ERD represents data as objects (entities) that are connected with standard relationships symbols which Illustrate an association between entities. ERD, there is a wide range of ERD notations used by data bases architects for reflecting the relationships between the data entities. According to the crow’s foot notation relationships are drawn as single labeled lines designating a certain kinds of relationship. Crow foot notation is a most frequently used ERD standard, because of improved readability of diagrams, with a more accurate use of space on the page.Entity Relationship Diagram Software, Design Elements - Crows Foot (Windows, Macintosh)

Process Flowchart

When trying to figure out the nature of the problems occurring within a project, there are many ways to develop such understanding. One of the most common ways to document processes for further improvement is to draw a process flowchart, which depicts the activities of the process arranged in sequential order — this is business process management. ConceptDraw PRO is business process mapping software with impressive range of productivity features for business process management and classic project management. This business process management software is helpful for many purposes from different payment processes, or manufacturing processes to chemical processes. Business process mapping flowcharts helps clarify the actual workflow of different people engaged in the same process. This samples were made with ConceptDraw PRO — business process mapping software for flowcharting and used as classic visio alternative because its briefly named "visio for mac" and for windows, this sort of software named the business process management tools. This flowchart diagram shows a process flow of project management. The diagram that is presented here depicts the project life cycle that is basic for the most of project management methods. Breaking a project into phases allows to track it in the proper manner. Through separation on phases, the total workflow of a project is divided into some foreseeable components, thus making it easier to follow the project status. A project life cycle commonly includes: initiation, definition, design, development and implementation phases. Distinguished method to show parallel and interdependent processes, as well as project life cycle relationships. A flowchart diagram is often used as visual guide to project. For instance, it used by marketing project management software for visualizing stages of marketing activities or as project management workflow tools. Created with ConceptDraw PRO — business process mapping software which is flowcharting visio alternative or shortly its visio for mac, this sort of software platform often named the business process management process flowcharts, flowchart symbols, process flow diagram, workflow diagram, flowchart maker

Data Flow Diagram

There are many ways to define the flow of information within a system. Structured-systems analysis method often uses data flow diagrams to show data flow, data storages and data processing visualization. These diagrams are easy to develop and quite useful. Here is a dataflow diagram presenting an example of the manufacturing process flow. The oval process shapes represent a process that controls data within the current system. The process may produce data or make some action based on data. Data flows are represented by lines. They show the movement of information through the system. The direction of the data flow is depicted by the arrow. The external entities are shown by rectangles. They represent the external entities interacting with the system. The data store objects (unclosed rectangles) are used to show data bases participating in a process flow.Data Flow Diagram

Data Flow Diagram (DFD)

In software engineering, it is important to understand how the system would cooperate with external sources, like data sources. To give this information a visual representation, data flow diagrams (DFD) were used for years. The entire system is usually divided into smaller ones, and all of them process data flows in appropriate ways. The visualizing business processes which engages the data transfer, is commonly preformed using DFDs (data flow diagrams). DFD is used to show the data flow processing and transformation. This DFD represents the electronic system of a customer purchase. It was created using Gane/Sarson notation. Data flow diagrams helps you to sort through and clarify transferring process making it available for analysis, and representation. ConceptDraw DFD solution introduces the vector library, containing the full set of icons from DFD notations.Data Flow Diagram (DFD)

Entity Relationship Diagram Examples

An abstract representation is usually the first thing you will need while developing a database. To understand the ways that databases are structured, you should look through entity-relationship diagram examples and see the notations features and attributes. With an entity-relationship model you can describe a database of any complexity. This Entity-relationship diagram is a tool for software developers. It enables every element of database to be managed, communicated and tested before release. This ERD was created using symbols advocated by Chen's notation. Because of a linguistic origin of the Chen’s notation, the boxes representing entities could be interpreted as nouns, and the relationships between them are in verb form, shown on a diagram as a diamond.Entity Relationship Diagram Examples
