Abstract: Embodiments may facilitate event processing for an ABAP platform. A business object data store may include a RAP model, including a behavior definition, for a business object. A framework may automatically transform the behavior definition of the RAP model into a producer event via an event binding and a cloud event standardized format. Information about the producer event may then be passed to an ABAP application associated with a pre-configured destination at an enterprise business technology platform. In some embodiments, a standalone API enterprise hub data store may contain an event specification. An ABAP development tenant of a business technology platform may automatically parse the event specification and translate the parsed information into high-level programming language structures that reflect an event type at runtime. An event consumption model may then be generated based on the event type.

Abstract: Disclosed herein are system, method, and computer program product embodiments for transferring data using a failsafe storage system. In some embodiments, a database receives a request to insert records of data. The records of data are to be transmitted from the source system to the target system. The database allocates a partition in the database based on a size of the plurality of records of data. The database inserts one or more records of data in each segment. The database inserts a create timestamp in each record header of the plurality of records. The create timestamp indicates a date and time when an insert of the one or more records of data is committed in a respective segment. The database inserts a delete timestamp in each segment of records of data, as each respective record of data is transmitted to the target system.

Abstract: Mechanisms are disclosed for visualizing and comparing an import and update history of content package objects in an analytic content system. Object to package mapping identifiers corresponding to the content package object are received. A package-identifier object state of a state of the content package object is received corresponding to an imported package associated with a particular package identifier. A modified object state to an original object state is compared prior to re-export of the content package object. The current object state to an original object state of the content package object is compared prior to importing the content package object from the imported package. A visualization of an import history of the content package object is displayed. In response to determining that an issue is present with a most recent import of the one or more content package objects, imports are rolled back to a stable set of objects.

Abstract: The present disclosure provides techniques and solutions for improved query optimization. A query plan is received, and at least a portion of the query plan is identified to be analyzed for logically equivalent query plans. A signature is generated for the at least a portion of the query plan. One or more query plans are identified that have signature that matches the signature of the at least a portion of the query plan, but where such query plans are logically equivalent, but not identical, to the at least a portion of the query plan. A query plan of the one or more query plans is substituted in the query plan for the at least a portion of the query plan.

Abstract: The present disclosure involves systems, software, and computer implemented methods for integrated data privacy services. An example method includes receiving a request to initiate an aligned purpose disassociation protocol for a purpose for an object instance. A determination is made as to whether a timestamp is stored for the purpose and the object instance that indicates an earliest time that the purpose can be disassociated from the object instance. The request is accepted in response to determining that no timestamp is stored for the purpose and the object instance that is greater than the current time. A status request is sent to applications that requests a status response that indicates whether an application can disassociate the purpose from the object instance. Status responses are received from at least some of the applications. A disassociation decision for the purpose and the object instance is determined based on the received status responses.

Abstract: Techniques and solutions are provided for database testing. In particular, aspects of the present disclosure facilitate “automatic exploration” of testing of database features, such as database commands. In particular, test definitions can be created for particular database features, where a test definition can have variants. Different test definitions can be combined into a composite test, which can include different variants for different tests. An executable test can be created that allows a database to execute a composite test. The present disclose also provides techniques and solutions for analyzing test results, particularly when voluminous test results are returned. In one example, test results for multiple iterations of a test can be compared. A change in test results, for example, can cause a test result to be flagged for further review. The composite tests, or result analysis techniques, can help provide better testing of database software to help identify software errors/bugs.

Abstract: Rows of first and second tables that share common values for one or more designated key fields can be considered partner rows to facilitate computer-based comparison of the tables. Responsive to a user request to compare the first and second tables, which designates field(s) common to both data tables as key fields and field(s) common to both data tables as comparison fields, a matches table is generated which includes the key field(s), comparison field(s), and a source field whose value indicates the originating table of the data in the row. For each set of partner rows, the matches table is populated with data from the partner rows. The data in the matches table is handled, and a results table is populated with the results of the handling of the data in the matches table and with data from any unpartnered rows in the first and second tables.

When a request for a database operation involving the virtual parameterized data object is received, the parameter information can be used to determine whether the request is correctly formed, or can be used in preparing a request to be sent to the remote system to be performed using the parameterized data object to obtain information specified in the request for a database operation.

Abstract: An automated extensibility framework is provided to automatically convert or migrate application extensions from a source system to be used on target applications in a target format. Extension artefacts of an extension of a source application on a source system are obtained. Each of the extension artefacts are parsed into a target format of a target platform based on a type of the corresponding extension artefact. Target applications of the target platform are identified based on an identifier of the source application. Extension simulations are compiled for each of the one or more target applications. Then, a user interface is provided which enables a user to select simulations from among extension simulations. Then the selected simulations are published to the target platform such that the corresponding extensions are implemented in corresponding target applications.

Abstract: Methods and apparatus are disclosed for extracting structured content, as graphs, from text documents. Graph vertices and edges correspond to document tokens and pairwise relationships between tokens. Undirected peer relationships and directed relationships (e.g. key-value or composition) are supported. Vertices can be identified with predefined fields, and thence mapped to database columns for automated storage of document content in a database. A trained neural network classifier determines relationship classifications for all pairwise combinations of input tokens. The relationship classification can differentiate multiple relationship types. A multi-level classifier extracts multi-level graph structure from a document. Disclosed embodiments support arbitrary graph structures with hierarchical and planar relationships. Relationships are not restricted by spatial proximity or document layout. Composite tokens can be identified interspersed with other content.

Abstract: Some embodiments provide a program that receives a set of data for a first record in a first table. The set of data includes a set of values for a set of attributes. In a data loading process configured to load a subset of the set of data into a subset of a first set of columns in the first table, the program determines that a first column in a first set of columns does not belong in the subset of the first set of columns. The program generates the first record in the first table. The program generates a value for the first column in the first set of columns that refers to a second record in the second table configured to represent a defined type of record. The program stores the value in the first column in the first set of columns of the first record.

Abstract: A database management system is described that can encode data to generate a plurality of data vectors. The database management system can perform the encoding by using a dictionary. The database management system can adaptively reorder the plurality of data vectors to prepare for compression of the plurality of data vectors. During a forward pass of the adaptive reordering, most frequent values of a data vector of the plurality of data vectors can be moved-up in the data vector. During a backward pass of the adaptive reordering, content within a rest range of a plurality of rest ranges can be rearranged within the plurality of data vectors according to frequencies of the content. The reordering according to frequency can further sort the rest range by value. Related apparatuses, systems, methods, techniques, computer programmable products, computer readable media, and articles are also described.
