php - Creating One-To-Many mapping where Many can be different object types -

I am looking for the feasibility of using a doctorate to recover an existing database.

I have three tables, one stockwork, sales order, work order . Type and not type in the StockRequest field. Used to decide if it is related to the sales order or the workload, and type no is the key to salesorder / work order .

What is the recommended method of maintaining this relationship?

Reading the theory reading, there is a mention of a repository class, which I can use only to get conditional based on the type of maintaining a stockroom entity only.

The other possibility will be the subclass of the StockRequest class so that I have SalesOrderStockRequests and WorkOrderStockRequests

I will make it with heritage and relationship, example:
The abstract class abotorder (generic field) class cells order abber order {} extends the class work order. Eber order {} then class stokeruest {relationship pointing to abstraction} and when you Get order () {$ $ - order; } Examples of theory u are either sales order or work order

MVC2 downloads seem to include only the VS2008 device. Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed.

This is your show-ref . You ask "Is there anything in this safe / head in the safe?" I ask, "what current head exists?" In practice, both of these are fair tests, because once you have a branch, so to achieve the HEAD , some mock values will indicate manually lack of editing It is very diffic...
