| Code Examples | DataSources are the files that execute functions that talk with a source
that stores or supplies data to the application, such as MySql,
PostgreSql, Oracle, DB2, MS Sql Server.
The DataSource abstracts the sending, retrieving, saving, and
deleting data to the model so that the model really behaves the same
regardless of what external source processes the data.
=> When creating custom DataSource, make sure the file name is
lowercase and has _source.php appended. An XML DataSource could
be named, for example, xml_source.php and would be placed in the
app/models/datasources directory. Naming the class object in the
DataSource file (in this case, for the XML DataSource) is done with
the following syntax:
class XmlSource extends DataSource {} |
