  • Re: Feature Request: Merge entity types

     Hi Tyler, That's a very interesting report.  Looks like you have overcome one of the main barriers to progress = "I have never heard of that so it can't be any good". [quote user="Tyler Young"]"and the tool generates a nice clean 5th-Normal Form database for you", database guys tend to shudder in ...

  • Re: Feature Request: Merge entity types

    A quick update for everyone that's interested: I carried on paring down the large model for a couple of days, then everyone else lost patience and wanted faster results. They decided that since we had such good results with building from the ground up on the first section I tackled, that we could use the same process and get quicker traction ...

  • Re: One tab per Object type: How do I expand an object type to show related facts?

    You could try zooming out and dragging things from the context window into an empty area, then deleting all the shapes that were previously there. The down side is that you've now lost all your beautiful layout. Sorry, not terribly helpful. To my knowledge there's no "get what's not on this page" filter.

  • Re: Cardinality constraints

    Hi JB, Dr. Halpin has formalized all ORM constraints such that an unpopulated relational database (the empty set) is always valid. So, for example, the set comparison constraints include subset, equality, and exclusion because these are not violated by empty sets. However, other set comparison operators (proper subset, proper superset, proper ...

  • Cardinality constraints

    I've got a question about cardinality: Is there a way to say # in {0,10} for example, a jury has either 12 members or 0 members. In the book, Information Modeling and Relational Databases it says you can use # = 12, but this doesn't account for the empty set when a table is created, but doesn't show an example of how to account for ...

  • Re: it is possible to link more than one object type to a label type

    Many things are possible, but not all are meaningful. The question you should ask is "what is meaningful". In my language, "Colors with Information" doesn't look like a meaningful fact type. "ColorSet includes Color", "Color is represented by RGBValue", etc, look like more meaningful things to say. You ...

  • Re: it is possible to link more than one object type to a label type

    Many thank for your feedback.. Concerning the WebsiteDesignElements this is part of a large conceptual schema. And this is really what I mean: a single instance designates a plurality of things. I am just wondering is the value type (information) is correct represented. Beouse I linke it with several object type. I am asking this because I ...

  • Re: it is possible to link more than one object type to a label type

    Sure, why not? You probably want to ensure that the same WebsiteDesignElement name doesn't get used for more than one of the related types though, using a mandatory exclusion (X-OR) constraint. But is it possible that what you really mean is that these are subtypes (all kinds of WebsiteDesignElement)? That will use a subtype connector, and ...
