组织地址
原标题:Organize address cache

我需要在我的Sql数据库中安排处理——坐标。 储存地址的最佳做法是什么? 是否需要压缩对加以描述或使用?

edit: Ok, let s I reassert my question. How to store long (up to 512) string in database if I need to search by exactly this string in future.

最佳回答

如果你绝对相信你的搜索扼杀能够实现正常化(例如:缩小所有额外空间,强迫降低案例等),以避免含糊不清,而且你需要寻找完全的匹配(即,你要么发现完全是正常的扼杀,要么不需要通过旁观、声音、部分配对等进行搜索,这就是我如何阅读你“正是这样描述”的话),你可以考虑计算扼杀的散码,把它列入行文和索引。

如果你使用重代码功能,使数人回归,你将有一个非常有效的准入指数。 当然,你仍然能够保持原封顶的印刷场和不同的准入方式。

可能的问题:虽然散列码能够尽量减少散射碰撞的可能性,但不能保证不会发生,因此,你也应当加以管理。

此外,除非你有很多地址和地址,否则,我怀疑速度的提高将值得一提。
