在 DBMS 中,可以使用锁来控制多个程序对数据项的访问:当程序要访问数据项时,要给数据项上锁。如果它仅仅是读取数据项,则通常上共享锁,这样其它的事务也可以同时读取该数据项。而若此程序是要修改数据项,则会给它数据项上独占锁,此时其它程序也就不能再访问这个数据项了。
对于同一个数据项,若有不同的程序同时给一个数据项上锁,且其中至少有一个是独占锁时,就表示它们发生了冲突。当发生冲突时,加锁的请求就会被拒绝。
每个加锁请求包含三个元素:锁模式、事务标识符和数据项标识符。两个程序可以同时给数据项上锁,前提是它们没有冲突。
在早期开发阶段,你需要编写一个简单的锁管理程序来处理加锁请求。它使用以下的规则来处理各种请求:
若一个加锁请求与先前的加锁请求没有发生冲突,则 DBMS 许可这个加锁请求;
一旦允许了一个加锁请求,则它将永远锁定数据项,不会改变,也不会释放;
如果一个程序的加锁请求与已有的锁发生了冲突,则 DBMS 拒绝这个加锁请求;
如果一个程序的加锁请求被拒绝,则 DBMS 忽略由这个程序发出的后续所有加锁请求。-the DBMS can be used to control the number of locks on the data, of the visit : When the procedures to access data items, data items to give locked. If it is read-only data, usually sharing locks, such other matters can also read the data item. And if this procedure is to amend the data, it will give information on items exclusive lock, other programs at this time, it will not re-visit this item of data. For the same data, if a different procedure for a data item unlocked but at least there is an

It s not my best code :)
but still worth looking at.
My greatest work is "Real Show", you can
find it on my web site:
http://www.emu8086.com/vb/
I wrote it both in Java and VB, so it
can work directly from your web site !!
I hope to update this sample, and add more effects
in the near future!
