represents a cursor for traversing or iterating over multiple records in a
database. It is the same as the Cursor, except that it includes the value
property.
provides a connection to a database; you can use an Database object to
open a transaction on your database then create, manipulate, and delete
objects (data) in that database. The interface provides the only way to get
and manage versions of the database.
provides asynchronous access to an index in a database. An index is a kind
of object store for looking up records in another object store, called the
referenced object store. You use this interface to retrieve data.
represents an object store in a database. Records within an object store are
sorted according to their keys. This sorting enables fast insertion,
look-up, and ordered retrieval.
provides access to results of asynchronous requests to databases and
database objects using event handler attributes. Each reading and writing
operation on a database is done using a request.
static, asynchronous transaction on a database using event handler
attributes. All reading and writing of data is done within transactions. You
actually use Database to start transactions and Transaction to set the
mode of the transaction (e.g. is it readonly or readwrite), and access an
ObjectStore to make a request. You can also use it to abort transactions.
