    1. This table or related slice is empty.
    1. COIf we pass in json/atom or xml we would need to parse and validate the inbound message. In particular, if we wanted to consider the DB as an (internal) service then we would want to parse and validate the inbound data, not for business rules, but just enough to parsed data to table fields. By your example I see you are considering a relational DB as an ObjectDB. Interesting.

    2. COYes, off-course everyone knows DAO objects. They abstract the application from the DB, but are themselves affected by changes in the DB. We can abstract this layer further if we consider only calling stored procedures. This is usually implemented by calling 'CreateInvHeader' and 'CreateInvDetails' as per my example. This is not complete abstraction at the business process level, which is what I am trying to achieve. Now, if I pass the database a structured document I have better abstraction and have little need to build aDAO layer. In large teams with dedicated DB dev's this is may be a plus.

    3. COI could be wrong here, having never tried it - but I don't think HttpModule would work in this scenario. The key here is to begin processing the request before the request has been fully received. It seems that by the time HttpModule is called the entire requests has already been read in (albeit not processed) by IIS. The only way to process a large request "while it is being read in" would be by processing the raw stream of data from the socket - or as close as possible to that. ISAPI filter seems low enough for this, if anyone knows better let us know.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
