projection: The projection operation treats nulls just like any other value when eliminating duplicates Thus, if two tuples in the projection result are exactly the same, and both have nulls in the same elds, they are treated as duplicates The decision is a little arbitrary since, without knowing the actual value, we do not know if the two instances of null are duplicates or not union, intersection, difference: These operations treat nulls just as the projection operation does; they treat tuples that have the same values on all elds as duplicates even if some of the elds have null values in both tuples The behavior is rather arbitrary, especially in the case of intersection and difference, since we do not know if the actual values (if any) represented by the nulls are the same generalized projection: We outlined how nulls are handled in expressions at the beginning of Section 334 Duplicate tuples containing null values are handled as in the projection operation aggregate: When nulls occur in grouping attributes, the aggregate operation treats them just as in projection: If two tuples are the same on all grouping attributes, the operation places them in the same group, even if some of their attribute values are null When nulls occur in aggregated attributes, the operation deletes null values at the outset, before applying aggregation If the resultant multiset is empty, the aggregate result is null Note that the treatment of nulls here is different from that in ordinary arithmetic expressions; we could have de ned the result of an aggregate operation as null if even one of the aggregated values is null However, this would mean a single unknown value in a large group could make the aggregate result on the group to be null, and we would lose a lot of useful information outer join: Outer join operations behave just like join operations, except on tuples that do not occur in the join result Such tuples may be added to the result (depending on whether the operation is 1, 1 , or 1 ), padded with nulls. c# ocr libraryYou can use WIA library to control the scanning process and tesseractdotnet for OCR.
