Re: Draw backs of Serialized Objects

Cor,

How would I create a single data source from multiple sources that may not
even be "databases"? For example, we have a state and federal system that
we send up XML queries and are returned XML result which we parse and add to
the final result set. Could I create a dataset (the final result) and
store all related returns into the data set?

Thanks!

Ben Kim

Ben,

You can load datasets in one instructions the sqldataadapter.fill, most
can be done generic as well, than you .

Try to make yourself a complete program
Select in top the Tab Datasource
Select database
Follow the wizard
Select again in top the Tab Datasource
Select that datasource drag it on your form.

Program made to get and update data.

I hope this helps,

Cor

Hello all,

We are diving into VB.NET 2005 head first, coming from a language called
Clarion. What are some of the drawbacks, if any, to serialized objects?
Should we just use streaming data? The environment will be as follows:

Multiple data stores (could be SQL Server databases across LAN, WAN,
internet... could be a mainframe system)
These disparate result sets will be combined into a single return
When returned to the requestor, the results will be displayed in a tree
list view

With that in mind, take a person inquiry. The requestor will be filling
out a "filter" form and sending the request in XQUERY or an XML like
language to a server process which could be located anywhere. The server
process would create separate threaded requests to each data store. Once
each data store has responded (or timed out), the responses are combined
and grouped into like names (IE: Social Security Numbers match and Last
Name as an example). This is serialized into an object or an XML
response is created and returned to the user, in Zipped format most
likely. The requestor unzips or unserializes the response and displays
it to the end user for further action.

In your professional opinion what is going to be the optimal way to
package the request and response given the data could be coming from a
local LAN or across the internet? We are looking for the least load on
the servers and wire/wireless systems and fastest response time.

Any input would be greatly appreciated!

Take care,

Ben Kim
