integrated new structured query facility (DBQuery) into the servlet demo (MetaCatServlet)
removed debugging code
fixed QuerySpecification to produce SQL that does UNION or INTERSECT set operations for query group combinations
finsihed basic functionality for structured queries based on the DBQuery and QuerySpecification classes
added code to build an index of the paths through the DOM tree to each node in the tree as the node is being inserted
db trigger xml_nodes_before_insert no longer in use
for safe nodeid generation
completed work on creating structured query prototype in DBQuery and QuerySpecification classes
added missed conn.close()
continued work on structured query. Now QuerySpecification generates SQL for a given xml input, and DBQuery uses that SQL to send the query to the db
fixed string broken over two lines
documentation cleanup
minor modifications to fix problems introduced with AccessionNumber module
docid is varchar2(55)new table xml_acc_numbersclear out db trigger xml_documents_before_insert
docid is String
docid is Stringdocid is generated from AccessionNumber.generate() call
gen acc # in new connectionchanging to static methodsinclude action parameter
continued work on structured query -- now it reads the queryspec xml docuemnt and can digest its contents
continued work on developing structured query functionality using the QuerySpecification class -- incomplete still
minor changes to TextNode
added incomplete classes for structured query
added result-set filter to DBSimpleQuery to only return specified document type
changed getDocID() only to: return docid;
put checkURLConnection(systemId) beforeits register in db or using from the parser
rewrote DBSimpleQuery and associated classes to no longer use Oracle's hierarchichal query syntax -- now this should work with any JDBC compliant backend DB
assign rootnodeid, docid for every node in xml_nodes table by given document
to use single transaction
no message
new class for registering of Accession numbers into metacat db
renamed DBSAXWriter to DBWriter
reincorporated Title registration code for documents
updated stylesheet script to reflect new table structure
updated documentation
Renamed DBSAXElement to DBSAXNode
rearranged API for incrementing the node index within the parent node
code consolidation, cleanup, and documentation
improved error handling when docid not found
general module cleanup
renamed ReaderElement to ElementNode
renamed BasicElement to BasicNode
continuing work on changing to DOM Text node model
continued changing to DOM TEXT node model
added new DB SQL utility query
