    Im doing a system analysis project in college on an airline reservation company, i find it particulary difficult, includes standard Requirements List,ERD's & DFD's. Is there any external websites/experts that i could contact for help or data that i could use

    Sorry OP I have no airline reservation specific links.
    I'm just truly amazed colleges are still teaching SDM & DFDs .. I haven't used them since the early 90s.

    Really, our lecturer told us that what we are doing is current if for example we were in the workplace

    SDM & DFD & ERD were used heavily on most projects I worked on in the late 80s to early 90s. But after the move to OO in the early 90s I never saw them again. UML offered a better fit with Event-Driven software that the then newish GUI environments. Plus UML offered a one stop shop from analysis through design and even coding. I've not been involved with big multinationals in years now, but I get the feeling that uml has fllen by the wayside now to be replaced with "agile" approaches.

    Regarding sample data, you could look in the library for Len Silverston's Data Model Resource Book volume 2. Chapter 8 travel.
    These books describe data models for industry that provide fairly comprehensive coverage of what is necessary for a substantial application.

    e.g. One of the models in volume one is the basis for the Apache OfBiz project.

    I completed a software development degree in 2006, it was a five year course. We never used SDM & DFD & ERD.
