What kind of issues can cause performance problems in the database tier of a web app driven by a MS-SQL database?

Are there any tools (ideally free) that can identify the root cause of such performance issues, if yes can you please detail?

Out of interest if a web app or maybe even an internal intranet app goes sluggish is it typically a result of an issue in the db tier, or elsewhere?

Are you performing regular maintenance on the database?  Reindexing, updating of statistics, backups?

Not being a DBA myself, can you let me know how...

reindexing
updating of statistics
backups

...affect performance.... and how someone could check if it is or is not being done?

Reindexing organizes the data in the database to make searching it faster.
Updating statistics helps SQL Server to determine ABOUT how many records exist in a table or index.
Backups are necessary and if you have the database in full recovery mode without doing transaction log backups then the log will fill forever.

I know there is the sql server best practices analyzer, does that identify if this sort of thing is being done or not? And does it only report on things that are essentially risks - or other stuff too?

I assume a process whereby re-indexing takes place on routine basis is more beneficial on larger databases? What is your recommendation on how often to reindex?

Statistics is what SQL Server uses to help determine the best query plan.  If SQL Server expects a particular table and criteria to return 5 rows, but instead it returns 5000, then the join type that it uses in the query may be completely wrong.
