Since We Last Met.....

Well, it was a good, long run. But the time has come for me to hang up my

hat, kick off my shoes, and relax a bit. After almost six years of doing this,

I’ll be stepping down as President effective January 1, 2001. In the amount

of time I’ve been in this position, LA Fox has gone from a local FoxPro

“watering hole” to a nationally-recognized group featuring nationally-

recognized speakers; the newsletter has become a 10-page staple every

month that gets circulated all over the country; LA Fox has its own award-

winning website. I don’t and won’t presume to take credit for any of this.

I’ve had a lot of support along the way from every corner of the FoxPro

community, as well as the LA Fox Board of Directors I’ve been so proud to

be associated with. That’s why it’s so important to fill out the “Membership

Survey” on page 7. Whoever steps into this position will need the same

guidance and support I had when I was new to all of this. Since I won’t be

vanishing off the face of the earth any time soon, I’ll still be around to lend

whatever support or guidance I can. I’m deeply grateful to everyone for their

support over the years and I can’t help but feel that our collective lives have

all been changed or affected by this experience.

Thanks,

Data. Developers use a DataNavigator for scrolling and editing an in-

memory XmlDocument. DataNavigators are functionally equivalent to the

W3C Document Object Model (DOM), but are more efficient and provide an

object model that maps nicely to the relational data view. DataNavigators

support XPath syntax for navigating the data stream. ADO+ also provides

an XMLDocument class for developers who want to continue to use the

DOM as an object model for XML rather than the more efficient

DataNavigator model.

Since all data can be viewed as XML, developers can take advantage of

ADO+ transformation and validation services for any data. ADO+ defines a

general transformation architecture that consumes a DataNavigator and

produces a new XmlReader. The .NET Framework provides a specific

transformation component that supports the W3C XSL Transformations

(XSLT) specification. ADO+ also provides a validation engine that uses XML

Schemas to validate an XmlReader. ADO+ supports schemas defined via

DTDs, XSD, orXDR.

Microsoft technologies. She is the author of Designing Component-based

Applications (Microsoft Press, 1998).)
