创建自己的数据库，例如oracle. [英] creating own database like oracle.

问题描述

我们正在开发一个需要数据库的应用程序.
但是我们不能使用oracle，sql，ms访问，因为它们太昂贵了.
如果我使用的是文件系统，则应用程序将变慢，并且可能会出现性能问题.
因此，为了克服这些问题，我们考虑开发自己的小型数据库，该数据库应类似于oracle.

有可能吗?
以及我们如何存储信息，请提供帮助
我们根本不想使用文件系统.

we are devloping an application that needs database.
but we cant use oracle ,sql,ms access because these are too expensive.
if i am using file system then application will become slow and performance issue may come.
so to overcome these problem we thinking to devlop our own small database that should work like oracle.

is it possible??
and how we can store information please help
we dont want to use file system at all.

推荐答案

您应该使用开放源代码且免费的MySql.

您无法创建自己的数据库.

You should use MySql that is Open Source and is free of cost.

You cannot create your own database.

请原谅我说的话，但是算了.您是不是想知道如果开发起来如此容易的话，为什么昂贵的产品如此昂贵?
首先，您需要确定需求和许可限制，而不是寻找解决方案.有多个具有ado.net提供程序甚至linq支持的开源和免费数据库引擎.
这里是一些:
Microsoft SQL Server Express [ Firebird [ ^ ]
MySQL [ ^ ]
PostgreSQL [ ^ ]
Oracle Express [

Forgive me saying this, but forget it. Didn''t you wonder why are the expensive ones so expensive if it would be so easy to develop one?
First off all, you need to determine your requirements, and your licensing constraints, than look for a solution. There are several open source and free database engines that have ado.net provider, even linq support.
Here are some:
Microsoft SQL Server Express[^]
Firebird[^]
MySQL[^]
PostgreSQL[^]
Oracle express[^]

And let''s not talk about non-relational, not sql based servers, and embedded (not client-server) editions...
