Ado 实现C++对象的存取,利用了串行化来实现c++对象保存到数据库，对程序所用方法稍做扩展可将甚至多个图象文件保存到数据库和文件。该方法的实质是使用内存文件 + 序列化保存C++对象，然后把内存文件以BLOB(二进制数据)方式存入数据库。ADO只是访问数据库的方式，也可以使用ODBC等。 -Ado to achieve C++ object access, use of serialization to implement c++ object saved to the database, the program slightly extend the methods used or even multiple image files can be saved to the database and documents. Essence of this method is to use serialization to save memory file+ C++ object, then the memory file to BLOB (binary data) method into the database. ADO is just a way to access the database, you can also use the ODBC and so on.
