Define repeating groups, partial dependencies and transitive dependencies and discuss how they are dealt with in the process of normalizing tables
Repeating group data occurs when multiple values for a particular attribute exist in a specific tuple (row). To avoid data redundancy, repeating group data needs to be removed from the table and placed in a separate table.
A partial dependency occurs when one or more nonkey attributes are dependent on (defined by) only part of the primary key rather than the whole key. This can only occur in tables that have composite (two or more attributes) primary keys. This is resolved by splitting the table in two.
A transitive dependency occurs in a table where nonkey attributes are dependent on another nonkey attribute and independent of the table's primary key. This is resolved by splitting out the independent data and placing it in a new table.
