Would someone be willing to offer a simple example of each to >help make the distinction clearer? I've given this a different subject line because it is a different thread. I've long felt a need for event-based software that would take a different approach to ordinary lineage-linked genealogy software and take a different approach. It woudl be useful for family history research rather than pure genealogy, and for other kind of historical research as well. I've even developed a sort of data model, which I've semi-implemented in creating a database to illustrate it. Let me try to give a concrete illustration of the difference. Say you are writing a biography of a person, and you want software to help you in your research. In a hypothetical event-based program you would enter people who impinged on the life of your subject as you do with genealogy software. Some would be genealogically related and some not. The birth event, for example, would have your subject's birth, with parents (obviously), but others like midwives, obstetricians and so on also linked. Twenty-one years later there might be a 21st birthday party, and you would have that as an event, and a description of the event, and then link people in your database to the event -- friends and relatives who attended. After entering a lot of events in the subject's life, you could create a chronology of the events, and of the people associated with your subject at each stage - parents, friends, teachers, classmates, bosses, and so on. If you were doing a biography, you could include in notes on various people their recollections of the subject, and the subjects recollections of them. In this hypothetical program, it should be possibly to import family relations (via GEDCOM) from lineage-linked software, but also from address books etc. Such software could be used for other purposes. Onme of the things I do research on is African Independent churches. I have three different databases or datasets -- churches, leaders and events. It would be useful to be able to link them in a relational database, but I don't have the skill to design such a database. Also, as software goes obsolete one would spend more time on redesigning it than entering and manipulating data, so you would never get any reseach done because you would always be tinkering with the tools. I once tried to do it with Paradox, but now everyone uses Access, and it would have to be rewritten from scratch, and I've never found books on Access that can tell me what I used to know about Paradox. So I lumber along using an old DOS program called Inmagic, which serves my purpose. I'm playing with a Windows program called askSam (I also continue to use the DOS version) which I use for entering raw genealogical data from different sources and material for other research projects. These are useful research tools, but an event-based relational program would be a useful addition. -- Steve Hayes from Tshwane, South Africa Web: http://hayesfam.bravehost.com/stevesig.htm Blog: http://methodius.blogspot.com E-mail - see web page, or parse: shayes at dunelm full stop org full stop uk
