I have just downloaded Sparx Enterprise Architect 7.5 but unfortunately I am not able to find a getting started guide or something like that.
I have gone through official site of Sparx but there is not step by step guide to learning Sparx EA.
I want a guide that will implement a small project and give instructions step by step so that I can understand and try out Sparx EA.
I did find a few sites selling step by step guides but at this point of time I do not want to spend money on them.
See also Enterprise Architect Product Demonstrations and the UML Tutorials.
Keep in mind, this is a UML tool. It's possible that part of what you need is a step by step guide to understanding UML. If these tutorials don't help you, I suggest UML Distilled: A Brief Guide to the Standard Object Modeling Language (3rd Edition) by Martin Fowler. Before reading this book, I felt that UML was this huge, tangled ball of twine. This book showed me the starting point, from which I was able to unravel the ball of twine.
