40 * Description: This file handles the Data base functionality for the application.
41 * It acts as the DB abstraction layer for the application. It depends on helper classes
42 * which generate the necessary SQL. This sql is then passed to PEAR DB classes.
43 * The helper class is chosen in DBManagerFactory, which is driven by 'db_type' in 'dbconfig' under config.php.
45 * All the functions in this class will work with any bean which implements the meta interface.
46 * The passed bean is passed to helper class which uses these functions to generate correct sql.
48 * The meta interface has the following functions:
49 * getTableName() Returns table name of the object.
50 * getFieldDefinitions() Returns a collection of field definitions in order.
51 * getFieldDefintion(name) Return field definition for the field.
52 * getFieldValue(name) Returns the value of the field identified by name.
53 * If the field is not set, the function will return boolean FALSE.
54 * getPrimaryFieldDefinition() Returns the field definition for primary key
56 * The field definition is an array with the following keys:
58 * name This represents name of the field. This is a required field.
59 * type This represents type of the field. This is a required field and valid values are:
73 * length This is used only when the type is varchar and denotes the length of the string.
74 * The max value is 255.
75 * enumvals This is a list of valid values for an enum separated by "|".
76 * It is used only if the type is ?enum?;
77 * required This field dictates whether it is a required value.
78 * The default value is ?FALSE?.
79 * isPrimary This field identifies the primary key of the table.
80 * If none of the fields have this flag set to ?TRUE?,
81 * the first field definition is assume to be the primary key.
82 * Default value for this field is ?FALSE?.
83 * default This field sets the default value for the field definition.
