Two fact tables can connect thru constellation schema. It
is different from Star and snowflake schemas. In
constellation schema , we can join to fact tables
surrounded by dimensions.

Answer / itesh
Yes it’s possible,
Since after all its a table, if you have the proper
relationship no problem,
Conceptually it’s correct to have a have confirmed
dimension but it can be manipulated,
Ex.
I have one fact a table FACT EOD this year i have joined
with EOD FACT Last year with time id .its working fine
Again
If you have two fact table A and B then create a derived
table from B Of the required key and measure only and join
with original fact table A ,
Better check with a sql query.
Nothing is impossible……

Answer / mallika
We can connect two fact tables by using constellation
schema or galaxy schema.
we have 3 types of schemas
star
snowflake
constellation or galaxy
in star schema we have data redundancy.we do not normalize
dimension tables.
in snowflake we normalize dimension tables to reduce space
boyh star aand snowflake we use only one fact and many
dimesion tables.in some situations we have to use more than
one fact table then we use constellation.but its vary
rarely used

Answer / nethaji
Yes,We can connect two fact tables by using confirmed
dimension indirectly or directly by confirmed fact.Here when
a fact appears in more than one fact table we can join using
this fact.
eg:
fact table 1 fact table 2
