ODB is an open source, Cross-platform, and Cross-database c++++ Object Relational Mapping (ORM) system. It can put C + + objects into the http://www.aliyun.com/zixun/aggregation/22.html "> relational database, without having to manually write any mapping code for tables, columns, or SQL."
ODB the execution transformation between the persistent class and the database that is automatically generated by the compiler, which is a true C + + compiler that can be compiled by portable C + + compiler rotation. ODB is not a framework, it does not dictate how you write applications, but it can be tailored to your style and architecture designed for C + + object persistence and non-interference in any other functionality.
ODB version 1.6.0 introduces a new conceptual feature that views are the result of a read-only mapping of one or more persisted objects or database tables, or the execution of a native SQL query. Other important features in this release support the deletion of persistent use of a query expression, support and mapping of smart pointers, ODB null semantic objects, and support for mapping blob types to std vectors < character >.
