+TESTS TO ADD
 
+* CACHE-TABLE-QUERIES
+* Test that ":db-kind :key" adds an index for that key. This is complicated by different
+  backends showing autogenerated primary key in different ways.
+* Large object testing
+* Test bigint type
+* :db-constraint tests
+* test *db-auto-sync* 
+* test SELECT caching
+* for-each-row macro
+* universal-time 
 
+COMMONSQL SPEC
+
+* Incompatible 
+
+ >> The functional sql interface 
+  
+    SELECT 
+      o keyword arg :refresh should function as advertised 
+
+ >> Symbolic SQL syntax 
+
+      o Complete sql expressions (see operations.lisp)
+
+         nvl (Oracle specific) 
+         userenv (Oracle specific) 
+	 minus (Oracle specific: does the same as EXCEPT) 
+
+      o variables (e.g., table identifiers) should be instantiated at runtime 
+
+
+VARIANCES FROM COMMONSQL
+
+UPDATE-OBJECT-JOINS:
+ Rather than simply reading the values for each
+ object, to meet CommonSQL spec need to generate a single
+ query to read values for all objects, up to max-len count.
+
+COMMIT,ROLLBACK,START-TRANSACTION: 
+ When COMMIT or ROLLBACK are called outside of WITH-TRANSACTION, an sql 
+ transaction must be explicitly started first with START-TRANSACTION. 
+
+OPTIMIZATIONS
+ 
+* Revisit result-type list creation,perhaps caching
+
+POSSIBLE EXTENSIONS
+
+* port Oracle backend to UFFI
+* large object support 
+* add support for prepared statements
+
+
