Repository
is a collection of something- commonly stored in DB
26

32
The procedure is a set of instructions for a person to follow when operating an information system
creating an account Uploading a file entering data
33
Structured processes
are formally defined standard processes structures processes are commonly used to support day-to-day operations, scheduling shifts, calculations -steps are fixed the same way every time
34
Dynamic processes
more adaptive and even intuitive can be used to help make decisions

75
crows foot notation
one or zero looks like an O and a 1 one and only one is 2 lines Zero or many is a triangle then an O one or many is a triangle and a line
76
normalization
converting poorly structured table into multiple well-structured tables
