Firebird System Tables (Part III)

This article idea (Part III) is belong to the someone that put comment on my previous article, so I just accomodate his/her idea. And I already arrange to become a view like this:

CREATE VIEW "vSYS_FindDependencies"(
"dependentName",
"dependentType",
"dependedOnName",
"dependedOnFieldName",
"dependedOnType")
AS
select RDB$DEPENDENT_NAME,
case RDB$DEPENDENT_TYPE
when 0 then 'Table'
when 1 then 'View'
when 2 then 'Trigger'
when 3 then 'Computed field'
when 4 then 'Validation'
when 5 then 'Procedure'
when 6 then 'Expression index'
when 7 then 'Exception'
when 8 then 'User'
when 9 then 'Field'
when 10 then 'Index'
when 14 then 'Generator'
else RDB$DEPENDENT_TYPE
end DEPENDENT_TYPE,
RDB$DEPENDED_ON_NAME, RDB$FIELD_NAME,
case RDB$DEPENDED_ON_TYPE
when 0 then 'Table'
when 1 then 'View'
when 2 then 'Trigger'
when 3 then 'Computed field'
when 4 then 'Validation'
when 5 then 'Procedure'
when 6 then 'Expression index'
when 7 then 'Exception'
when 8 then 'User'
when 9 then 'Field'
when 10 then 'Index'
when 14 then 'Generator'
else RDB$DEPENDED_ON_TYPE
end DEPENDED_ON_TYPE
from RDB$DEPENDENCIES;

The idea is to know the dependency on some entity in the database. Perhaps it is also usefull for everyone.
