Make sure you read the N5 post on design notations<\/a> for examples of Structure Diagrams, Flow Charts and Pseudocode.<\/p>\n

Wire-Framing<\/strong>: A wireframe can show how a website will look and how its navigations structure works; can be as simple as a rough sketch or can be a detailed design showing colour combinations and images<\/p>\n

Entity Relationship Diagrams<\/strong><\/p>\n

Relationships can be represented graphically using an Entity-Relationship (ER) diagram.<\/p>\n

There are many different notations for ER diagrams, we will use crow\u2019s foot notation.
\n\u2022 The names of entities are written in boxes joined by straight lines.
\n\u2022 At the \u201cmany\u201d end the line forks.
\n\u2022 At the \u201cone\u201d end the line it judt joins the box.<\/p>\n

\"ERD\"<\/p>\n

Data dictionaries<\/strong><\/p>\n

A data dictionary is a design notation used to show the fields required in each table of a relational database, including field types, validation required, etc.<\/p>\n
