Guidewire Query API General Best Practices - CORRECT
ANSWER-Use the property reference (EntityType#Property) for
type-safe access to the properties on the query entity type
Use the property reference to filter query results, join to another
entity type, order rows in the result set, or to specify a column
for a row query
Use query.contains() after other query.compare() operations
against indexed columns for better performance against large
data sets
Guidewire Query API - Denormalized columns improve
performance of - CORRECT ANSWER-Ends with searches
Case-insensitive searches
Guidewire Query API Anti-Patterns - Bring back only the data
you need by - CORRECT ANSWER-Avoid filtering query
results in memory

Perform filtering in the database
Avoid the use of where(), first(), last(), firstWhere(), and
lastWhere()
Guidewire Query API Anti-Patterns - use dot notation with care
because - CORRECT ANSWER-accessing foreign keys or array
fields retrieve additional entities into memory
Guidewire Query API Anti-Patterns - Check for existence of an
entity when the number of results is not important by -
CORRECT ANSWER-Verifying the results of a targeted query
are not empty
Avoiding hasMatch(), countWhere(), and select().Count
How to count on DB level?
Guidewire Query API Anti-Patterns - When a count is

Support database aggregate functions (Avg, Count, Min, Max,
Sum)
