  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.
  44 *
  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.
  47 *
  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
  55 *
  56 * The field definition is an array with the following keys:
  57 *
  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:
  60 *           �   int
  61 *           �   long
  62 *           �   varchar
  63 *           �   text
  64 *           �   date
  65 *           �   datetime
  66 *           �   double
  67 *           �   float
  68 *           �   uint
  69 *           �   ulong
  70 *           �   time
  71 *           �   short
  72 *           �   enum
  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.
