+is a collection of tools that make it possible to define this behavior in
+another way. First, the ".h" file is replaced with a relational database schema

+each of the ".c" module files is replaced with a ".sql" version in which all
+data manipulation in the bodies of C functions and procedures is re-coded by
+using a variant of the static embedded SQL protocol.
 
 Note that each of the tools comprising the LDI system define the behavior of
 such a process or thread, and are therefore also coded in this manner. Thus, the
-tools themselves also constitute important benchmarks for their own evaluation.
