Ax 2012 component existence in all layers and models - axapta

Question

Can anybody help me how to find a component existence in all layers and models installed in that layer. i.e find all the layers and models in which a particular component(ax 2012) exists.
For example how to find all the layers and models in which CustTable exists.
Is there any class or table that stores this information.
please help me. Thanks in advance.

Comment is limited :(
Do you need to search through source code? Are you searching for merge candidates? Tell me your business requirement.
Here is the query returning elements that contains CustTable within selected models:
SELECT
me.Name ElementName
, Layer.Name Layer
, mm.Name ModelName
, ElementTypes.ElementTypeName
FROM ModelElement me
JOIN ModelElementData med
ON med.ElementHandle = me.ElementHandle
AND me.ParentHandle = 0 -- only root elements
JOIN ModelManifest mm
ON mm.ModelId=med.ModelId
JOIN Layer
ON Layer.Id = med.LayerId
JOIN ElementTypes
ON me.ElementType = ElementTypes.ElementType
WHERE EXISTS (
SELECT null
FROM ModelElement child
JOIN Sources s
ON s.SourceHandle = child.ElementHandle
AND s.LayerId = med.LayerId
AND child.RootHandle = med.ElementHandle
WHERE cast([SourceText] as nvarchar(max)) like '%CustTable%'
)
AND mm.Name IN ('Foundation','I4C')

You can try search within _model databese with next query (this searcehs all code references - table, class, form, dataset, ...):
SELECT TOP 1000 [SourceHandle]
, met.ElementTypeName
, ro.Name object
, me.Name method
, l.Name Layer
, mm.Name Model
, cast([SourceText] as nvarchar(max)) sourceTxt
FROM [Sources] s
join ModelElement me on me.ElementHandle=s.SourceHandle
join ElementTypes met on met.ElementType=me.ElementType
join ModelElement ro on ro.ElementHandle=me.RootHandle
left join ModelElementData med on med.ElementHandle=s.SourceHandle and med.LayerId=s.LayerId and med.ElementHandle=me.ElementHandle
left join Layer l on l.Id=s.LayerId
left join ModelManifest mm on mm.ModelId=med.ModelId
WHERE cast([SourceText] as nvarchar(max)) like '%CustTable%'
If you need all records, remove TOP 1000.

SELECT DISTINCT
ro.Name object,
ro.ElementType type,
l.Name Layer,
mm.Name Model
FROM Sources s
join ModelElement me on
me.ElementHandle = s.SourceHandle
join ElementTypes met
on met.ElementType = me.ElementType
join ModelElement ro
on ro.ElementHandle = me.RootHandle
left join ModelElementData med
on med.ElementHandle = s.SourceHandle
and med.LayerId = s.LayerId
and med.ElementHandle = me.ElementHandle
left join Layer l
on l.Id = s.LayerId
left join ModelManifest mm
on mm.ModelId = med.ModelId
where ro.Name = 'InventDim' order by mm.Name, ro.ElementType
In addition to the query suggested by the authors, a small change was made according to my requirement is giving the right results.
