Give my respect to Jobber. Jobber looks like a fireman of Rolia. When people say: Jobber, please ......I always envy those people whom I never catch up with.

You are flattering me. ....Come in, please.Actually, many people in this forum are more knowledgable than I am. The fact is that they don't want to explain themselves, or they are not good at doing that.
By the way, you usurped my nickname. I hope have not done that by mistakes. In another word, I understand it as your sense of humor.

Coin the new words....I think you haven't got my point. "jabber" is a true English word. For whatever reason, you put it into "jobber". For English-speaking people, this is a word derived from "job". Since we are talking about job things, it is really amazing to see such a migration. If you did it by mistake, it is an amazing one. If it did it on purpose, it manifests your sense of humor.

you said just right, details come in please!有股票数据放在远端,是dbf格式的。我以ftp方式定时(每两分钟)将dbf文件传回的主机。将该数据转到oracle数据库里。
但因为要完成客户对股票交易信息的定制检索,即股票一在价格达到$10时要以短信息通知用户。所以要在股票交易时间内比对两个表--交易行情表与客户定制信息表。现在是在oracl里完成的。但对数据库压力较大。
想将两个表读如内存中草捉。要求用java实现。
其中交易行情表要每两分钟重新读入。要很方便的进行检索。请教在java里才用和钟结构(或几种的结合)能较好的完成这个任务。如能给出较细的方法最好。谢谢
