ESRI products can use many RDBMSs with the aid of ArcSDE, Oracle being one of them. They make a big deal out of partnering with Oracle but without SDE you cannot fully utilize Oracle's Inherit Spatial Technology and even then it's problematic. Intergraph on the other hand can fully utilize Oracle Spatial. Any application that recognises the Oracle Spatial type can benefit from the addition of Radius Topology. Basically it's an addition to the relational model that allows the storage, interpretation and retrieval of spatial elements directly in the DB. The main reason this is beneficial is speed and having your data in an open environment. OpenGIS is a concept that has not quite been realized yet because one of the two biggest players in the filed does not want it to be fully open. They are "protecting their customer base through proprietary formats" was a comment the owner once made. I think we all know what that really means. And to their credit they have recently implemented some widely accepted standards such as VBA. Not a big deal in the ESRI world because they have Spatial Data Engine(SDE) that they use as a good between for supported RDBMSs. Essentially does the same thing, you just need to buy it too :o) I'm posting this thread to DBATech too (for futher discussion if needed). :o) > -----Original Message----- > From: accessd-bounces at databaseadvisors.com > [mailto:accessd-bounces at databaseadvisors.com]On Behalf Of Charlotte > Foust > Sent: Tuesday, September 16, 2003 10:41 AM > To: Access Developers discussion and problem solving > Subject: RE: [AccessD] OT: Today's GIS > > > I thought Oracle was the RDBMS of choice for ESRI. > > Charlotte Foust > > -----Original Message----- > From: John B.
