CHAPTER 10: System Architecture
checklist
initial cost&TCO
scalability
system's ability to expand,
change/downsize
web integration
avoids many of the connectivity and
compatibilty probs
legacy system
interface requirement
processing options
security isses
planning the
architecture
servers
server
client
companies linked the stand-alone
computers into network
mainframe architecture
server-based
processing
client/server
architecture
overview
design style
fat&thin
client/server tiers
two-tiers design
three tiers design
middleware
enable the tiers to communicate and pass
data back and forth
provides a transparent interface
can integrate legacy system and
web-based application
internet-based
architecture
developing e-commerce
solutions in-house
packaged solutions&
e-commerce service providers
many vendors offer
turnkey system for companies
another option is
managed hosting
corporate portals
provide access for cutomers,
employees,suppliers & public
cloud computing
scalling on dmenad
requires significantly
more bandwidth
web 2.0
wiki
internet operating system
envisions a second generating the web that
will enable ppl to collaborate,interact
& share information more dynamically
processing method
online processing
avoid delays and allows a constant
dialog between the user the system
batch processing
require significant fewer network
resources than online system
combined online & batch processing
network models
OSI reference model
7 layers
layer performs a specific fx
offer a set design standards
network protocols
transmission control protocol/internet protocol
FTP
network topology
hierachical network
bus network
ring network
star network
mesh network
routers
can connect to larger, dissimilar network
gateway
