Object Oriented Analysis Approach | Module Oriented Analysis Approach |
System is seen as collection of objects, each with a
functional purpose |
System is seen as a set of functions, data,
process and their inter-relationship |
Easy maintenance of system and at low cost | Maintenance is costlier. Proper and detailed
documentation is needed |
Since Object can be reused in different applications, it promote reuse of code in large system |
Reuse of code is limited and infrequent |
Simpler to implement in Distributed system | Difficult to implement in distributed system |
Leads to system that are more flexible to change | Lead to less flexible system |
Ideal for large system | Ideal for small systems |
