Systems and methods for facilitating a purchase are described. A user logs in to a payment service provider site. The user provides authorization to use a one-page checkout service. The user's information is captured during the session, and a cookie is placed on the user's device. When the user goes on a merchant website and checks out using the payment service provider, the payment service provider detects the cookie on the user device. The payment service provider uses the cookie, and in one embodiment, centrally stored information, to populate the one-page checkout page with the last used payment. In various embodiments, the one-page checkout page also displays a shipping address.

Method, system, and medium for one-page checkout

One-page checkout

A method and system for modeling of object-oriented database structures, translation to relational database structures, and dynamic searches thereon. The user may create, edit and manipulate a user's object database (dynamically translated into a set of relational database structures), to create, edit and manipulate objects for that object database (dynamically translated into data for those relational database structures), and to create, edit and manipulate queries to be applied to that object database (dynamically translated into queries to be applied to those relational database structures). A meta-model of the user's object database, which is itself an object database, and which has itself been translated into a set of relational database structures for manipulation by a relational database engine. The meta-model comprises a set of classes, objects, and relationships between classes which model the classes and relationships between classes of the system. Each of these classes may comprise a set of searchable properties, and each of these relationships may comprise an inheritance relationship (between a base class and a derived class) or a data-model relationship (such as a one-to-one, one-to-many, or many-to-many relationship). The data model of the user's object database is modeled by actual objects in the meta-model, and editing or manipulating the user's object database is modeled by creating, modifying, or deleting objects in the meta-model. The meta-model also models itself, in the same manner as it models the user's object database, and may be manipulated in the same manner as the user's object database.
