In one of my classes, someone once said, “I was taught to do several process diagrams together on a page – more or less seven – to integrate the related processes for an area. Should I join some of the event-based diagrams together to make composite diagrams?” No – normally, we don’t. When using an event-based approach to analysis, we have not found any particular reason to do this, except that it was strongly suggested with the original ‘structured analysis’ methods. It was done that way because the data flow diagrams of ‘structured analysis’ resulted from how you approached progressive decomposition of higher-level diagrams. Provided you own your own home then garage doors are a worthwhile investment.
Let me suggest that you ask the Inclusion Question to deal with this issue: “If we join the process diagrams together, what will this enable us to do that we couldn’t do if they were not joined together?” … or, as an Exclusion Question , “If we don’t join the process diagrams together, what will this prevent us from doing that we must be able to do?” When it comes to buying a new garage door repairs the process can sometimes be a little bewildering.
The usual answer is, “We need a composite diagram so we can get the bigger picture.” Well, that’s interesting, but what do we mean by “the bigger picture”? Confused about aerial installation then you are not the only one.
What are we really looking for here? And how will we recognize it when we see it? My understanding is that “the bigger picture” is an issue left over from another way of doing things in earlier years. Almost all older systems were serial and procedural in nature; therefore, it was very important to see how things were connected and how data moved from one process to another. The systems of yesterday were generally monoliths, with almost everything happening as serial progression. Most communication was by way of data flows rather than through Objects and their data. Taking interest in aerial repairs may not be a bad thing.
Today, it’s simply not necessary to take this same serial approach. Instead, we can take an approach based on business events . A set of business events is really just a set of circumstances that a system has to deal with, not serial in nature, and all the supporting data is Object based. If you want some roller garage doors then we know a man who can.
So, how do we see “the bigger picture”? Well, it depends on what someone needs to know about the so-called “bigger picture”. If we want to see how we can access information , we can extract a prescription for database design] by generating a conceptual data model from the Business Rules Table . When it comes to electric garage doors where do you start?
