Client Side Datase / MemoryTables

[salman]

Hi,
We are working on an stock market application to buy and sell stock
market shares. Clients are connected through local lan, we are easily
maintaining and updating the client database when client perform any
operarion like sell/buy shares.
We are planing to use our applicaion from dailup connection or
internet, but we are facing a problem that we are using normal database
operation like insert/delete/update, which takes lots of time on
internet while our application requiment is real time operation.
So we plan to use In-Memory Database sort of thing or Memory Tables in
client application so that client could not change the database entries
manually and application could perform easily and fastly.
My question is that how can we create these memory tabels/database, is
there any API available to create these things, or we have to create
our own API, or any other solution for that problem.

Thanks Peter!
We are supposing that client system does not have any database like sql
or oracle etc.
and also we don't want to change our client application (something will
be possible). So we want to create tables in client memory so that
application read/update data from memory to save time without
read/update from our server, we known that there would be requirement
to load data in clinet memory each time the client application
start/connect with server (like - synchronize all ServerData and
MemoryData at start of application)

Thanks.
