Parser
Refactoring
• Challenge:
– Overly
complex,
hard
to
add
new
syntax
• SoluNon:
– Create
an
internal
parse
tree
borom-­‐up
– Create
an
AST
(Abstract
Syntax
Tree)
from
the
parse
tree
and
the
user's
context.
– Have
syntax
rules
that
are
more
precisely
defined
and
are
closer
to
the
SQL
standard.
– More
precise
error
messages
– Berer
support
for
larger
syntax
rules
in
the
future
