/*********************************************************************************
* Description: This file handles the Data base functionality for the application.
* It acts as the DB abstraction layer for the application. It depends on helper classes
* which generate the necessary SQL. This sql is then passed to PEAR DB classes.
* The helper class is chosen in DBManagerFactory, which is driven by 'db_type' in 'dbconfig' under config.php.
*
* All the functions in this class will work with any bean which implements the meta interface.
* The passed bean is passed to helper class which uses these functions to generate correct sql.
*
* The meta interface has the following functions:
* getTableName() Returns table name of the object.
* getFieldDefinitions() Returns a collection of field definitions in order.
* getFieldDefintion(name) Return field definition for the field.
* getFieldValue(name) Returns the value of the field identified by name.
* If the field is not set, the function will return boolean FALSE.
* getPrimaryFieldDefinition() Returns the field definition for primary key
*
* The field definition is an array with the following keys:
*
* name This represents name of the field. This is a required field.
* type This represents type of the field. This is a required field and valid values are:
* <20> int
* <20> long
* <20> varchar
* <20> text
* <20> date
* <20> datetime
* <20> double
* <20> float
* <20> uint
* <20> ulong
* <20> time
* <20> short
* <20> enum
* length This is used only when the type is varchar and denotes the length of the string.
* The max value is 255.
* enumvals This is a list of valid values for an enum separated by "|".
* It is used only if the type is <20>enum<75>;
* required This field dictates whether it is a required value.
* The default value is <20>FALSE<53>.
* isPrimary This field identifies the primary key of the table.
* If none of the fields have this flag set to <20>TRUE<55>,
* the first field definition is assume to be the primary key.
* Default value for this field is <20>FALSE<53>.
* default This field sets the default value for the field definition.
