* 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:
*           �   int
*           �   long
*           �   varchar
*           �   text
*           �   date
*           �   datetime
*           �   double
*           �   float
*           �   uint
*           �   ulong
*           �   time
*           �   short
*           �   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 �enum�;
* required  This field dictates whether it is a required value.
*           The default value is �FALSE�.
* isPrimary This field identifies the primary key of the table.
*           If none of the fields have this flag set to �TRUE�, 
*           the first field definition is assume to be the primary key.
*           Default value for this field is �FALSE�.
* default   This field sets the default value for the field definition.
