system development life cycle

system life cycle
is a process to create a system that involves the following steps
1 of 20
feasability
is the solution possible? economical to produce?
2 of 20
analysis
this defines the problem that needs to be solved
3 of 20
design
working out the best method to solve the problem
4 of 20
implementation
is the process of creating the system and putting it in to the working place. there are a couple of types:direct, parallel and pilot conversion
5 of 20
maintenance
this is the process of keeping the system running smoothly, ironing out glitches and adapting it if the problem changes
6 of 20
deliverable
this is the final system that is produced given to the client
7 of 20
waterfall method
one step followed by the next step, followed by the next following into the next
8 of 20
spiral method
rapid prototyping followed by extensive maintenance to make it suit the problem
9 of 20
requirement specificaion
what is needed to do
10 of 20
DFD
data flow diagrams
11 of 20
system flowcharts
a way of representing data flow around the system
12 of 20
data dictionary
a list of every pice of data that is stored in the system
13 of 20
dry run testing
walking through the process ignorign existing flows
14 of 20
unit testing
testing small sections of the program to make sure it function properly
15 of 20
integration testing
the process of bringing all the modules together and testing them together
16 of 20
system testing
testing everything on the complete product
17 of 20
acceptance testing
these are automated test written by the customer to check that the system has been implemented properly
18 of 20
blackbox
testing algorithms
19 of 20
phased implementation
parallel new and old system run at the same time
