The document provides recommendations for developing an e-menu prototype for a Thai restaurant. It discusses software development processes based on RAD, prototyping, and direct observation. System analysis and design documents are created, including use case diagrams, class diagrams, ER diagrams, and workflow diagrams. Technical designs include an initial e-menu design using MVC, communication between .NET and iOS platforms using web services, and Xcode development with classes, view controllers, storyboards, and application settings.

Diagram
• Use Case Diagram
Description
- The use case diagram is an
UML modeling tools for
capturing business requirements
- It can describe what e-menu
system does and the views of
what users needs (Kendall
2011)
Benefit
• It enabled the learner to
understand the scope and
features of systems operated by
external users.

6. 6 2 .2 ) C L A SS DIA G RA M
Diagram
• Class Diagram
Description
- Class diagram is data model of
objected-oriented concept,
which aims to enhance software
quality (Revelle, Gethers and
Poshvanyk 2011)
Benefit
• It enabled the learner to take
advantages from an object-
oriented design e.g. reusability,
abstraction, module integration.

7. 7 2 .3 ) ER DIA G RA M
Diagram
• ER Diagram
Description
- ER diagram is data modeling tool
for linking between data object in
the real-world and data modeling
details (Rob, Coronel, and Crockett
2008).
Benefit
• ER modelling can reduce ambiguity
of communication e.g. defining
primary keys, foreign keys,
relationships and cardinalities.
(Connolly and Begg 2011)

Diagram
• Workflow diagram
Description
- Work flow diagram describes
processes when customers come
until they leave from restaurant.
Benefit
• The work flow enabled the learner
be able to confirm the business
process with the restaurant
manager.
• It also was used to design statuses
of ordering and requesting services
as shown in the next slide.

The classes in this folder are used for
communication with Web Services e.g. generating &
1 10_WebServices All classes
parsing XML, and converting data types between
Web services and Xcode
This Class contains all web services functions, which
are easy to use. The main objectives of this class is
ServiceUtils to encapsulation using web services and to convert
communication with web services from
asynchronous to synchronous.
3 20_Utils This class contains static variables, such as Order,
SharedClass TableNo and ArrayMenuByCategory, to use as
public variables.
This class collects general reusable functions e.g.
GettingStringDataFromSettingFile,
ServiceUtils
ConvertTableNoToNo and ConvertNoToTableNo
functions.
Classes in Folder 10_WebServices are used for communication with Web Services (ASP.Net)
