 need info about extensibility in other databases Hi there, after we have GiST with concurrency and recovery support (thanks to PosGIS community for support) I'd trying to find info about level of extensibility support in other major RDBMS's like Relational Extenders of DB2, Cartridges in Oracle and (?) in MS SQL. With current GiST one could develope new datatype, index access methods and queries and everything will have automatically concurency and recovery support. New datatype could be not just a subset of existing types, but completely new. What's about other RDBMS ? btw, "GiST programming tutorial" is available in Russian, http://www.sai.msu.su/~megera/postgr..._tutorial.html Regards, Oleg __________________________________________________ ___________ Oleg Bartunov, sci.researcher, hostmaster of AstroNet, Sternberg Astronomical Institute, Moscow University (Russia) Internet: oleg@sai.msu.su, http://www.sai.msu.su/~megera/ phone: +007(095)939-16-83, +007(095)939-23-83 ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster      |
