摘要:
A mesh structure can be a type concept that extends internal tables or other data structures of a business programming languages (e.g., ABAP) by associations, as known from a data object meta-model. A mesh can include a set of operations, such as for example iteration via an iterator object and selection of instances expressed by a path language. A mesh structure can be optimized for read access and traversal, and can provide a working area that is processed with statements in the business programming language to implement one or more core services directly from the mesh data structure. Related methods, computer program products, and systems are described.

摘要:
An application system includes a first process configured to execute an application program, wherein the application program is operable to use a set of data structures. The application system also includes a second process configured to interpret a markup language document. A transformation template is configured to specify a symmetric mapping between the markup language document and the set of data structures. A transformation virtual machine runs in association with the first process and is operable to execute the transformation template. The transformation virtual machine is operable to perform a symmetric transformation between the markup language document and the set of data structures to allow the first process and the second process to exchange information.

摘要:
A table can be replaced with a view transparently to the application. For example, a data dictionary can specify that the view is to be substituted for the table. At runtime, application operations on the table are redirected to be performed on the view. Validation can be performed to ensure congruence between the table and the view. Can be useful for situations where a view with enhanced functionality is desired to be used in place of the table without re-coding the application.
摘要:
A system and method are described for performing a mapping between persistent data objects and a database. For example, a method according to one embodiment of the invention comprises determining whether an attribute having a generic type is an instance of a persistent class; and if the attribute is an instance of a persistent class, then mapping the attribute to a discriminator column holding the type associated with the attribute and further mapping the attribute to a reference column holding a key associated with the attribute.

摘要:
A new query language can be embedded in a business application programming language (e.g., the ABAP language). A query language consistent with implementations of the current subject matter can be based on a graph data-model of connected business objects (BO) or other data objects and can be designed as an efficient query language embedded into the business application programming language runtime, thereby allowing expression of business logic in a declarative manner.

摘要:
According to some embodiments, a programming language in an application server may access different database server implementations, wherein the programming language accesses content of database tables via work areas derived from the database tables. A database table may be mapped to a work area such that each column in the database table is mapped to a corresponding component of the work area (having a default component type based on the column type of the associated column). It may be determined that a particular column in the database table is to store large object data content, and a new mapping to a work area may be defined such that a particular column maps to a corresponding component having a component type other than the default component type.
