RE: Query kernel
For the front end (such as OQL), have you considered using JavaCC to
recognize the statements and create the appropriate QueryObjects used by the
QueryKernel? I believe there are grammars currently for OQL and others that
are freely available.
Just my two cents, even though it may not directly effect the design of the
kernel.

Subject: Re: Query kernel
hi falko,
i had some doubts while thinking
about the kernel.
it has to have front ends for OQL, SODA etc etc
say for OQL, we need to have some interpreter that
converts the queries to some statements which will
be understood by the kernel.
and the kernel returns the result of the query
in a manner understood by the front end which then
outputs it to the user.
if all the above is fine then it is just
a matter of retrieving data from the DB.
what other functionalities do u think this kernel should have??
reply soon please
bye
das
