3. What are we doing?
Pay attention to emails (class
cancellation, updates, etc.)!
Talk about Phase 1!
Venn Diagrams & Boolean Logic !
Review fields & records & look at a
database
4. Phase 1
"Confusion, frustration, doubt" are
to be expected at this point.!
If you want to meet with me, let's set
up an appointment right now.
5. Boolean Logic &
Venn Diagrams
When you search in a database, you
are doing an "exact match" search!
Based on Boolean algebra (aka
algebra of sets aka Boolean logic)!
Boolean Logic is represented using
Venn Diagrams
6. "Exact Match"
Search
type of algorithm in most databases!
different from "Best Match" search
based on an algorithm (formula) that
evaluates relevance (e.g. Google Search)!
"You get what you ask for" search (you
retrieve exactly the documents that
match the query)

of stored data in a A record (aka tuple) is
database. a single set of related
data held within a
database.
