ODB C++ ORM 1.1.0 adds support for containers, relationships, composite values

[boris kolpackov]

I am pleased to announce the release of ODB 1.1.0.

ODB is an open-source object-relational mapping (ORM) system for C++. It allows you to persist C++ objects to a relational database without having to deal with tables, columns, or SQL and without manually writing any of the mapping code.

Major new features in this release:

* Support for storing containers in the database, for example:

    #pragma db object
    class person
    {
      ...

      std::set<std::string> emails_;
    };
                                                                

* Support for unidirectional and bidirectional object relationships, including lazy loading. For example:

    #pragma db object
    class employer
    {
      ...

      #pragma db inverse(employer_)
      std::vector<lazy_weak_ptr<employee> > employees_;
    };

    #pragma db object
    class employee
    {
      ...

      shared_ptr<employer> employer_;
    };
                                                                

* Support for composite value types, for example:

    #pragma db value
    class name
    {
      ...

      std::string first_;
      std::string last_;
    };

    #pragma db object
    class person
    {
      ...

      name name_;
    };
                                                                

* Support for optional object cache (session).

* Support for native SQL statement execution.

* Support for customization of object pointers that allows you to use smart pointers to return, pass, and cache persistent objects.
