– Link tables in order to light DB tables:• event2user table• users2group table• event2group table• comment2event table

OOP Design

• C# asp .NET language is OOP• ASP.NET for web development: ability to build

pages composed of controls. • The framework allows usage of many languages

such as HTML, javascript• Easy way to use SQL with ASP .NET.• ASP (Active Server Pages) .NET encourages

the programmer to develop Web: appropriate for Web applications

2006 April20

Communication client-server

• Web Server IIS (Internet Information Server): intermediate server

2006 April21

OOP Design: Web Controls

• Web Controls: – code can assign its properties and respond to its

events. – Controls know how to render themselves: produce

segments of HTML and Javascript.

• Web User Controls:– Independent class, with its personal

methods/functions/fields– Used when the object we program doesn’t have to be

visible all the time, depending on the user’s demand.

2006 April22

Other Classes

• Two main WebForms:– Login WebForm: first webpage that the user

see when connecting to the WebCalendar– MainPage WebForm: the calendar page with

all week details and functionalities as previously described.

• Class “Functions” that contains all the “help functions” needed by the forms/web controls.

2006 April23

Graphic design

• Based on simplicity and clarity

• Ergonomic

• Friendly-user design

• Logos according to situation: – simple understanding for new users
