I'd also like to get a feel for the magnitude of the task, so I'd like to
ask what database systems you think should be supported.
mysql, postgresql, sqllite are the 3 I am aiming at in my personal
implementation.
I had lunch yesterday with a database expert and discussed the matter
with him. He advised that we take a driver-oriented approach in which we
define a common API for all databases (modeled at high level after e.g.
JDBC to reuse that accumulated experience), and then define a few
drivers for popular DBMSs in hope that users interested in supporting
additional DBMSs will contribute additional drivers using the initial
drivers as a template. Eventually when D and its database API become
successful, DBMS providers themselves will write the drivers.
It would be great if we could leverage another already widespread driver
architecture. There are two that come to mind, and I looked into both:
JDBC and ODBC. The first requires either bridging into Java or
translating Java driver code to D. The second is widespread on Windows
but less so on other OSs. So probably we'll need to define our own
drivers. (This also brings dynamic linking as a possibility.)
