My understanding is that we are stuck at this place:

One position:

 We support all data types native to the machine on which the client is

run. The ADO handles all conversions, gives native type for each channel

connected, gives sizeof infromation for allocating storage, and returns the

value in that type of variable - where the space is provided by the user.

The other position:

 We support a limited number of types that support all of the data that

we need to support. The server puts the data into one of these limited set.

Otherwise, it is the same as above.

The difference in the two, is that the ADO handles many different types in

the first position and in the second position the server has to put data

into one of the limited set and the ADO only handles the limited set.

Is this right?

In the first place - the ADO is big and handles a lot. In the second place,

it is small and does not support everything.

Our clients will be about 70% JAVA, and 30% C. How much work is required to

get the functionality in the first option into all of these platforms? How

much is it in the second options?

Where is the example codes that implement the various client functions with

the proposed libraries?

Where is the protocol that was going to be placed on the wiki?

Thanks,
Bob
