+-- mappings
+
+-- objectClass mappings: these may be viewed as structuralObjectClass, the ones that are used to decide how to build an entry
+-- id a unique number identifying the objectClass
+-- name the name of the objectClass; it MUST match the name of an objectClass that is loaded in slapd's schema
+-- keytbl the name of the table that is referenced for the primary key of an entry
+-- keycol the name of the column in "keytbl" that contains the primary key of an entry; the pair "keytbl.keycol" uniquely identifies an entry of objectClass "id"
+-- create_proc a procedure to create the entry
+-- delete_proc a procedure to delete the entry; it takes "keytbl.keycol" of the row to be deleted
+-- expect_return a bitmap that marks whether create_proc (1) and delete_proc (2) return a value or not

+-- attributeType mappings: describe how an attributeType for a certain objectClass maps to the SQL data.
+-- id a unique number identifying the attribute
+-- oc_map_id the value of "ldap_oc_mappings.id" that identifies the objectClass this attributeType is defined for
+-- name the name of the attributeType; it MUST match the name of an attributeType that is loaded in slapd's schema
+-- sel_expr the expression that is used to select this attribute (the "select <sel_expr> from ..." portion)
+-- from_tbls the expression that defines the table(s) this attribute is taken from (the "select ... from <from_tbls> where ..." portion)
+-- join_where the expression that defines the condition to select this attribute (the "select ... where <join_where> ..." portion)
+-- add_proc a procedure to insert the attribute; it takes the value of the attribute that is added, and the "keytbl.keycol" of the entry it is associated to
+-- delete_proc a procedure to delete the attribute; it takes the value of the attribute that is added, and the "keytbl.keycol" of the entry it is associated to
+-- param_order a mask that marks if the "keytbl.keycol" value comes before or after the value in add_proc (1) and delete_proc (2)
+-- expect_return a mask that marks whether add_proc (1) and delete_proc(2) are expected to return a value or not

--- entries
-

--- referrals
-
+-- objectClass mapping: entries that have multiple objectClass instances are listed here with the objectClass name (view them as auxiliary objectClass)
+-- entry_id the "ldap_entries.id" of the entry this objectClass value must be added
+-- oc_name the name of the objectClass; it MUST match the name of an objectClass that is loaded in slapd's schema

+-- referrals mapping: entries that should be treated as referrals are stored here
+-- entry_id the "ldap_entries.id" of the entry that should be treated as a referral
+-- url the URI of the referral

values (4,'http://localhost');
-- procedures
-
+-- these procedures are specific for this RDBMS and are used in mapping objectClass and attributeType creation/modify/deletion
