    1. Don't Use Size=1 or Font-Size=xx-small

    Tip: Do not use the smallest standard font size of "1" and "xx-small" for any text you actually want a visitor to read. The smallest font size should be reserved for text you don't care if the visitor reads like the copyright notice at the bottom of the page.

    3. Aggregation

    Short Definition: Aggregations indicate a whole-part relationship, and are known as "has-a" or "is part of" relationships. An Aggregation relationship is indicated by a line with a hollow diamond.

    4. Association

    Short Definition: An Association is a generic relationship between two classes and is represented a line connecting the two classes. This line can be qualified with the type of relationship, and can also feature multiplicity rules such as one-to-one, one-to-many, many-to-many, 0 or 1 to many, etc.

    5. Composition

    Short Definition: A composite relationship means that a class cannot exist by itself. It must exist as a member of another class. A composite relationship is indicated by a solid line with a solid diamond head pointing to the part class. Alternatively, you can show this relationship graphically with the part class nested in the whole class.

    Nicole is positive our CMAS expired 6/30/2008.

    Because the other contract expired June 30th, they might be dating the PO in June. If so, we "may" be okay because the PO will clearly say the work will start on July 1.

    Not sure if this will help but it's at least a possibility and can buy us some time while we renew.



    Regarding...
    Work After Expired CMAS
    Can a CMAS contractor provide products or services after the CMAS contract expires?

    Hi Graham,

    >>...customer in a Customer table and orders would be in an Orders table?

    Yes customers in customer table and orders in the orders table as usual.

    >>...how many orders have been placed by a specific Customer belong in the Customer library (class) or in an Orders library?

    Since Number of Orders is a property of a customer, I would put that property in the Customer class but you are correct that that custom method would indeed count the values from the orders table. It uses the orders.db table. Although classes frequently map 1 to 1 to tables in a database, when creating reusable code, you need to switch your thinking. You need to switch from a data-centric view to an object-centric view.

    >>Or would you have a method in Customer.lib which called a method in Orders.lib?

    If I wanted the ability to retrieve the number of orders of a customer in the Orders class, sure, you could design it that way. And yes, you could use aggregation where the Customer class "has a" orders object in it. In ObjectPAL, you would have to simply make use of an Orders.lib custom method.

    Interesting article.

    I feel the example based on interrogating the 'Customer' table to find out how many orders have been placed somewhat dubious in terms of database design - surely you would only have one record per customer in a Customer table and orders would be in an Orders table?

    As far as OO design goes would a method to find out how many orders have been placed by a specific Customer belong in the Customer library (class) or in an Orders library? Or would you have a method in Customer.lib which called a method in Orders.lib?

    The Future of Paradox Blog

    Authored by , Posted By mprestwood
    If you're still using Paradox for any of your business database applications, you need to put a plan together now for converting to another development tool or at least understand what the future is likely to hold. If you're a power-user or researcher working with data, stick with Paradox at least for now.

    Windows XP Not Supported After June 30, 2008

    Microsoft plans to discontinue sales of Windows XP on June 30, 2008. Because XP is a tried and true OS, and because of numerous problems with Vista, many users and IT departments would prefer to stick with XP. InfoWorld has an initiative to keep XP alive indefinitely. You can help.

    If you've used computers for more than a few years, you know that you don't wonder IF a hard drive will fail - you wonder WHEN. It just happened to me - again. But this time it looks like the results will be pretty painless. The reasons? * RAID Level 1 * Superb Hard Drive manufacturer warranty support
