Package Pyblio :: Module Store

Module Store

Overview

Contains the base classes and interfaces used to define a database of records.

The databases can be managed in different physical stores. To create a new database, get a specific store implementation with the get function, and call the provided dbcreate function:

>>> db = get ('file').dbcreate (path, schema)

Once this is done, the database is ready to accept records:

>>> record = Store.Record()
>>> record.add('title', u'my title', Attribute.Text)
>>> key = db.add(record)

See Also: the Database class to know what operations can be performed on databases.
