Tools

• Language Java
• Database Sybase of Adaptive Server Anywhere
  (ASA)
• PDA OS WinCE

9
Techniques learnt -Java

• Language structure (object-oriented)
• Defining Instantiable Classes
• Input with Applets
• Selection Statements
• Repetition
• Characters and Strings
• Arrays

10
JAVA

• Object-Oriented Programming
• Java application can easily be delivered over the
  Internet, or any network, without operating
  system or hardware platform.
• E.g a pc , a network computer, Internet screen
  phone
• was designed to run programs securely on networks

11
JAVA (cont)

• can work everywhere.
• don't care what kind of computer, phone, TV, or
  operating system they run on.
• allows programmers and users to do with Web
  pages.

12
JAVA (cont)

• The Internet and private networks become our
  computing environment.
• is being built into next-generation telephones,
  TV set-top boxes, and many other consumer and
  business devices.
• can run directly on computer (without requiring a
  browser), or on servers, on large mainframe
  computers, or other devices.

13
Sybase(ASA)

• Adaptive Server Anywhere (ASA) is a fully
  featured DBMS (Database Management System) with
  transactional integrity, automatic rollback and
  recovery, declarative RI, triggers and stored
  procedures.

14
Sybase(ASA) cont

• ASA offers a number of features
• row level BEFORE and AFTER triggers
• long varchar and BLOB (Binary Large Object) up to
  2 gigabytes
• varchar up to 32k
• declarative RI with cascade actions
• all character and decimal data is stored var-len,
  using only the spaceit needs

15
Sybase(ASA) cont

• ASA is designed to be low-maintenance
• File size automatically grows
• self-tuning
• re-uses space from deletes
• ASA also includes
• Java stored procs
• Stored procedure debugger

16
Sybase(ASA) cont

• What platforms are ASA supported?
• E.g.
• Windows 95/98/ME, NT, 2000, CE
• Novell NetWare
• IBM AIX
• Linux (RedHat)

17
Sybase(ASA) cont

• What application is ASA good for?
• It is generally good at OLTP (Online Transaction
  Processing) and can be used as a basis for a
  general database project. 
• A major area for ASA databases is with
  applications that need to distribute the database
  with the application as a general storage area
  for internal components, but the database is not
  a major part of the deliverable. 
• ASA has excellent ODBC (Open Database
  Connectivity) support, which makes it very
  attractive to tools oriented towards ODBC.

18
WinCE

• Which is an Operating System platform for a
  broad range of communication and mobile-computing
  devices.
• The first products based on Windows CE began
  within November 1996 (six years), which is OEM
  version

19
WinCE (cont)

• 32-bit, multitasking and multithreaded operating
  system that providing support for a variety of
  devices.
• Share and exchange information with Windows-based
  PCs
• High performance in limited memory configurations

20
WinCE (cont)

• Why choose?
• User recommend
• Compactable with Java language and Sybase
• Interface is similar with other Windows OS (User
  friendly)

21
Solved Problems

• 1. For define problem
• Base on the real original system, can define
  problem more realistic.

22
Solved Problems

• 2. For DFD
• Can make sure which data flow is really useful
• 3. For database
• No need to make the Food File
• Sybase has been used which suggested by user

23
Solved Problems (cont)

• 4. For Internet
• No need to count internet service time
• 5. For Computer Language
• Which Language should be use?
• Confirmed by user

24
Work done

• Finish system planning
• Finish system Analysis
• Discuss System Requirement
• Studying Java, WinCE, Sybase
• Surfing website
• www.java.sun.com
• www.sybase.com
