[dna-issues] [JBoss JIRA] Updated: (DNA-49) Sequence DDL files

[ https://jira.jboss.org/jira/browse/DNA-49?page=com.atlassian.jira.plugin.... ] Randall Hauch updated DNA-49: ----------------------------- Fix Version/s: 0.7 (was: Future Releases) Assignee: Barry LaFond (was: Bojidar Penchev) Complexity: High (was: Medium) Priority: Major (was: Minor) Barry has picked up this work, and has developed a very nice sequencer capable of parsing the more important DDL statements from several different dialects, and constructing a graph structure that is largely the same for all dialects (though some dialects will result in dialect-specific properties and maybe nodes). The sequencer attempts to detect the dialect by running multiple parsers and finding the one with the "best fit". One very interesting capability of this sequencer is that, although only a subset of the (more common) DDL statements are supported, the sequencer is still extremely functional since it does still add all statements into the output graph, just without much detail other than just the statement text and the position in the DDL file. Thus, if a DDL file contains statements the sequencer understands and statements that the sequencer does not understand, the graph will still contain all statements and those statements understood by the sequencer will have their full detail. Since the underlying parsers are able to operate upon a single statement, it is possible to go back later (after the parsers have been enhanced to support additional DDL statements) and re-parse only those incomplete statements in the graph. Support for additional statements and additional dialects will be added in the future under different issues. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
