- M: The customisation issue we have addressed by developing the whole system
- M:in an object-oriented language. We wrote our own language called
- M:Smallworld Magik for this, because we felt that all the commercially
- M:available languages had shortcomings for what we wanted to do. This is
- M:closer to Smalltalk than C++ in flavour. We fully support multiple
- M:inheritance, polymorphism, dependencies etc. The vast majority of the
- M:GIS code which we supply is written in Magik, and the customer can extend
- M:and customise the system in Magik.
-
- M:database is completely continuous with no partitions, so we don't have
- M:to worry about edge matching, which is often a significant cost in
- M:data capture.
-
- M:spatial indexing built in at a deep level to give us good performance.

- I tried to send an e-mail message to Peter, but I believe that it did not
- go through. I am interested in further information about the above
- sections I have taken out of his document. When I finger his address I
- get that it is not operating.
- I hope that he can pick this up when he reads GIS-L
- Thank you and Merry Christmas and a Happy New Year
