1) Many of the topic titles are vague.
a) Almost all of the titles for the built-in function topics do not indicate that the topic is about a "function".
The word "function" should be added to all of the reference topics (In the Reference Manual) that discuss the built in functions
b) Almost all of the titles for the data type topics do not indicate that the topic is about a data type.
The words "data type" should be added to all of the reference topics (In the Reference Manual) that discuss the data types
c) Some of the SQL statement topic titles do not include the word "statement" in the title and they should.
2)Some of the topics use the same title, but discuss very different things. Each topic title in the Derby documentation should be
LOCK TABLE statement in the Reference Manual (http://db.apache.org/derby/docs/dev/ref/rrefsqlj40506.html)
and in the Tuning Guide (http://db.apache.org/derby/docs/dev/tuning/ctunoptimz11775.html)
This is just one of several examples.
