Proxy offers are effectively "canned queries" Their main use is to integrate legacy systems, such as existing databases, into an OMG trader You can integrate the legacy system by building a front-end Lookup object and by storing a constraint recipe that constructs the query in the back end's native database language Another (although unusual) use for proxy offers is to build smart factories With this technique, a client can create a new object by submitting a query to a trader It is understood that this query cannot match an existing object but will match an existing proxy offer When the trader calls the Lookup interface in the matching proxy offer, the implementation of the Lookup object creates an object that matches the client's criteria instead of looking it up in a database The newly created object is returned to the client from the import operation From the importer's perspective, nothing unusual has happened; the importer simply went looking for a service and found it However, behind the scenes, the proxy offer was used to create a new object that matches the client's requirements Proxy support is optional, and few trader implementations support proxy offers For this reason, we do not provide further detail about proxies and constraint recipes in this book You can consult the CORBAservices specification [21] for further details 1938 Preferences A service request made by an importer can optionally include preferences, which control the order in which service offers are returned to the importer For example, the importer can request that service offers be returned in order of increasing value of a property or that service offers be randomized Here again is the service request from page 831, modified here with a preference Find the cheapest set of steel radial tires on offer in the San Francisco Bay area with a speed rating of at least 120 mph, size P205/65R15, made by either Bridgestone or Goodyear Make sure that either Visa or MasterCard is accepted for payment This service request not only looks for a set of tires that match our requirements but also makes sure that we get the cheapest such set on offer 1939 Policies Policies control non-functional aspects of a trader For example, an importer can use policies to impose a limit on the number of matching service offers that will be returned from an import operation The specification describes quite a large number of policies; they can be categorized as follows Trader policies Trader policies apply to a trader as a whole For example, a trader can limit the number of offers it will search during an import operation Import policies

Import policies are specified for each individual import operation and affect only that operation For example, the importer can limit the number of matching offers that will be returned Link policies Link policies apply to each individual federation link and are set when a link is created For example, there is a link policy to control whether or not a particular link will be followed by default during import operations

The IDL for the OMG Trading Service is large and offers a wide range of functionality and features The specification defines three IDL modules CosTradingRepos The CosTradingRepos module contains the functionality required to define, examine, and delete service types CosTrading The CosTrading module contains most of the IDL for the trader It consists of 11 interfaces that provide the functionality to create service offers, perform imports, maintain trader federations, set policies, and so on CosTradingDynamic The CosTradingDynamic module contains a single interface called DynamicPropEval Dynamic properties contain an object reference to this interface; the trader invokes an operation on the interface to get the current value of a dynamic property The sections that follow discuss these three modules in detail
