Abstract: Methods and apparatus, including computer program products, are provided for providing a query language based on a model. In one aspect, there is provided a computer-implemented method. The method may include receiving a first query; generating, based on a model including metadata representing a data structure, a second query specific to the data structure stored in a database; and sending the second query to the database. Related apparatus, systems, methods, and articles are also described.

Abstract: In accordance with aspects of the disclosure, a system and methods are provided for managing business objects in memory. The system and methods may be provided for defining a context of one or more input parameters of data used to determine one or more properties of one or more business objects, defining one or more rules associated with the one or more properties of each business object, and generating a metadata model for each business object based on the context of the one or more input parameters of each business object and the one or more rules associated with the one or more properties of each business object.

Abstract: Embodiments of the invention relate to computing, and in particular, to a systems and methods for a querying a database. Certain embodiments implement a model-driven database query (“the SADL query”) facilitating a design-time tool that allows a developer to create the query based upon existing Business Objects (BOs) and their associations. This SADL query leverages mapping between business-layer entities and database-layer entities, such mapping being derived from association metadata already extant in the business model used to create the Business Objects. In certain embodiments, query views may be based upon associations present within the business layer, rather than upon database-level entities (such as joins or restriction rules) that are typically relied upon in conventional query creation. Embodiments of the present invention may thus align query creation more closely with the structure of the business layer, and may also render query design agnostic relative to the identity of the underlying database.

Abstract: Methods and apparatus, including computer program products, are provided for providing value help. In one aspect, there is provided a computer-implemented method. The method may include receiving at least one field of a row of a list presented at a user interface; transforming, at a service component rather than the user interface, the at least one field into a query; and sending the transformed query to a database. Related apparatus, systems, methods, and articles are also described.

Abstract: A plurality of domain-specific service adaptation languages can be supported by a back-end service adaptation system to provide runtime access to a runtime instance of a data object comprising data stored in a repository. By defining a language-specific data access service and parser for each domain-specific service adaptation language, a single, service adaptation language-independent compiler and interpreter can prepare and execute a runtime load that includes an execution plan for retrieving and converting data from the repository for delivery in a data object according to a query request from a consumer runtime environment. A consumer using the consumer runtime environment can define the service adaptation language to be used and provide a parser and source code to enable access to business object data using the back-end service adaptation system.

Abstract: A bulk service interface can be instantiated for each of at least one service provider providing a plurality of business objects using a stored definition of a plurality of metadata properties relating to generation of a user interface that incorporates content of a plurality of business objects. The bulk service interface can query the stored definition and access, in a bulk metadata access process, dynamic metadata required for instantiation of the plurality of business objects. If the stored definition has not previously been received, a default bulk services access process that queries an existing dynamic metadata access interface of each of the plurality of business objects can be initiated to retrieve the dynamic metadata from each of the plurality of business objects. An instance of the user interface can be generated using dynamic metadata accessed by the bulk service interface and/or the retrieved by the default bulk services access process.

Abstract: A computerized method for accessing business object data stored in a data buffer of a server computer includes providing an application program interface (API) having a function for specifying a set of paths through a business object stored as a data structure in a data buffer of a server computer. Each of the paths included in the set of paths specifies a plurality of nodes of the business object for accessing hosted data at the plurality of nodes. The method further includes receiving a set of parameters for the function of the API. The set of parameters specify the set of paths. The method further includes issuing the set of parameters to the server computer, retrieving hosted data from the plurality of nodes for each path in the set of paths; and transmitting to a client the hosted data retrieved from the plurality of nodes.

Abstract: A back-end service adaptation system provides access to normalized data in a data repository for a consumer runtime environment sending a query request for denormalized data. The back-end service adaptation system can include a data access service layer, a parser layer, and a back-end service adaptation runtime layer. The consumer runtime can use a service adaptation definition language (SADL), and the parser and data access service can be configured to convert and translate the SADL request for the back-end service adaptation runtime layer.

Abstract: Systems and methods for providing application services through business object views. In one aspect, a definition of at least one business object (BO) is included in a metadata of an application platform. The definition includes descriptions of entities of the BO, and an identification of a service provider of the BO. The service provider instantiates the business object in response to an application service request. In a further aspect, a definition of a business object view (BOV) is included in the metadata of the application platform. The definition includes description of entities of the BOV, and an identification of the BO. The BO is a data source of the BOV. In one other aspect, a transformation describes a mapping of BOV entities to data source BO entities. A service corresponding to a core service of a BOV entity is called at the BO service provider based on the mapping.

Abstract: A system may include a database comprising stored data and a business process platform including business object metadata defining business objects representing the stored data. The business process platform may receive a query from a user to retrieve data from a first business object node of a business object, the business object representing stored data, determine whether the user is authorized to traverse all associations of a SELECT list of the query, determine whether the user is authorized to traverse all associations of a WHERE clause of the query, determine whether the user is authorized to retrieve any instances of each business object node of column specifications of the SELECT list of the query, and, if the determinations are affirmative, executing the query to retrieve a first result set.
