    see Data Modeling for a good introduction to data modeling and relational design

    the best tools for creating logical models are paper and pencil

    for very large models, you can use Graphical Modeling Tools

    Logical Design is basically a layout or the structure of how the project/business will flow from scratch going to the objective of the whole process. Normally, these fundamental steps are not so technical at the start, just guidelines or blueprints of how a certain processing will progress or "flow". Then from there softwares and techical designs will step in.

    Yes a Data Flow Diagram is still a logical design as long as it compasses the whole process. It actually depends on the terms used.
