(I'm pulling all this from memory when I read up on it a couple years back so 
if I am mistaken feel free to correct me).

There are a few other reasons to think twice about sqLite. One that comes to 
mind is that there is no real typing. If you write text to an int column it 
will happily do so. Normally an SQL database will throw an error. If you count 
on error callbacks to check for data consistency (I do not because I don't want 
to have to write a function to parse the many things that might go wrong with a 
DB write) then this will be an issue.

Another is that sqLite does not support all the SQL query statements that mySQL 
or MSSQL and other high end SQL databases might <glances over at Lynn>. I 
understand each has a superset of statements for special purposes. I am talking 
about things you might expect are supported of fully supported, and will be 
surprised to find it doesn't.

Thirdly, you cannot simply update an sqLite schema any way you like. It only 
supports one auto-incrementing column, and new columns are appended to the end 
of the schema. To insert a new column before another column, you need to dump 
the data, create a new schema, then import the data into the new schema.

The big reason I can think of to use it is that it is very easy to set up and 
maintain. Security is handled by the file system it sits on. It's not 
accessible via network protocols. It can be backed up and restored with simple 
file protocols. No worries about data dumps and restores.

Here is a useful article on sqLite limits:

Having said that, the SQLite website is itself driven by a SQLite database,
which they use as an example of how SQLite can work in a networked
environment under reasonably heavy, read-only loads.  Of course they have
almost exclusively readers, except when they themselves are changing the
website due to a new release or something similar.  As you say, WAL allows
concurrent reading with one writer so even that probably isn't a problem in
their environment.
