Abstract: Embodiments are directed to managing a data model that includes data objects associated with layers of the data model may be provided. A lineage model that includes lineage objects that has one or more lineage objects associated with a layer may be provided. A lineage object associated with a layer may be activated. A first portion data objects may be determined based on the activated lineage object. An anchor object may be determined from the first portion of data objects. A search of the data model may be employed to provide dependency information based on a position of the anchor data object in the data model. A second portion of data objects may be determined based on the dependency information. A report that includes a list of the second portion of data objects, the dependency information, or the like, may be provided.

Abstract: Techniques are described for employing a queue service as an intermediary to communicate messages between separate networks. A first proxy service may access a request generated by a client device operating in a first network, the request initially indicating a destination that is a server device operating in a second network. The request may be an application level protocol request. The first proxy service may modify the request to include, as a destination, a queue maintained by a queue service that is accessible from the first and second networks. The first proxy service may enqueue the modified request in the queue. A second proxy service operating in the second network may retrieve the enqueued request and communicate the request to the server device. One or more responses generated by the server device may be enqueued in a queue by the second proxy service for delivery to the client device.

Abstract: A featured offer for an item in an electronic marketplace is selected based on factors such as estimated conversion rate and contribution profit. Qualified offers from various merchants are analyzed using a variety of filters, algorithms, and/or criteria to select an offer that meets the goal(s) of the marketplace provider, while providing customers with offers having terms that are also attractive to the customer. Secondary offers and/or advertisements also can be selected using similar approaches.
