> if b.title_sci=b.title, then we get cc=0

get it, or set it? If the former, what guarantees that the rule is followed?

> if b.title_sci<>b.title then we have to see the master

That contradicts what you wrote before: if base.title_sci = base.title or b.issn1=b.issn2 or b.issn=b.eissn then this is match and CC=0 else cc=1. Which is correct?

> if in master this m.title_sci is dog and for the same row m.title= cat

Loose language yields errors. Especially when writing specs, be literal. Do you mean: if m.title_sci <> m.title?

> then this is match as per the master(a way we say this is match
> though the colun doesnt match in base table )

You seem to mean to say this is a condition for (i) setting and (ii) consulting the corresponding master row. Is that correct?

You've given apparently inconsistent variants of the condition for setting and updating the master version of the row. We're writing pseudocode for a requirement. It needs to be unambiguous. Here's your requirement as I understand it so far, unresolved issues I've so far identified are in comments:

in a join of b to m on (title_sci, title, issn1, issn2, issn, eissn, databas) ...

if b.title_sci=b.title or b.issn1=b.issn2 or b.issn=b.eissn then 
  set                   -- WHAT IF B.CC=1?
  if then
    ???                        -- YOU SAID SET b,cc=0 BUT IT ALREADY IS 
  else if m.title <> m.title_sci
    set .cc=0                  -- OR M.CC?
  end if
end if

For readability & clarity, please put your corrected spec, in a format like the above, inside a pair of BBCode code tags (the 1st tag is the word "code", the 2nd is "/code", each surrounded by square brackets).
