> Gwen and I have this proposal.
> Most importantly, not to have NULLs representing one too many things!!
> SQ_CONNECTOR -> will be now call SQ_CONFIGURABLE ( it is basically a table to hold
entities that will specify configs)
> Add another field to it, that is CONFIGURABLE_TYPE ( it can be connector or driver at
this point ). we can have a standard id for  Driver that we will use in the SQOOP, having
nulls to represent things is not clean since "none/null" can mean different things at different
> Next,
> We propose to split up the SQ_FORM ( which is the SQ_CONFIG after 1498) to SQ_JOB_CONFIG
and SQ_LINK_CONFIG ( it will parallel the SQ_JOB_INPUT and SQ_LINK_INPUT)
> Direction is only relevant to job config ( and henceforth the job inputs). So we will
store the DIRECTION field in JOB_CONFIG.
> If we want to have SQ_CONFIG, we can have it with the SQ_CFG_TYPE and then it will have
 FK on the SQ_CONFIGURABLE, so we know which entity owns this config easily. 
> We can then have SQ_JOB_CONFIG and SQ_LINK_CONFIG have a FK on SQ_CONFIG.
> Alternatively, dont have SQ_CONFIG, and just have SQ_JOB_CONFIG and SQ_LINK_CONFIG and
have a FK directly to SQ_CONFIGURABLE, both will have the CONFIG_NAME and INDEX fields.
