摘要： Embodiments include method, systems and computer program products for predicting adverse drug events on a computational system. Aspects include receiving a personalized data set including a plurality of real-time drug doses for a first drug or drug combination and a plurality of corresponding real-time adverse drug reaction tolerance data for the first drug or drug combination for a patient. Aspects also include receiving known drug data for a candidate drug or drug pair. Aspects also include calculating, based upon the known drug data and the personalized data set, a predicted adverse drug reaction tolerance for the candidate drug or drug pair at a candidate dosage, wherein the predicted adverse drug reaction tolerance is personalized to the patient.

摘要： Entities and relations associated with source code of a program are extracted. An entity completion on the extracted entities and relationships is performed to produce a knowledge graph of the source code. Repeated patterns of relationships are identified from the knowledge graph across the source code.

摘要： Staging data record changes from a faster storage medium to a slower storage medium using data query rewriting is provided. In response to receiving a data query corresponding to a particular data record, it is determined whether the data query is one of a transactional data query or an analytical data query. In response to determining that the data query is a transactional data query, the transactional data query is rewritten to apply transactional delta changes to the particular data record on a storage-class memory of a computer. In response to determining that the data query is an analytical data query, the analytical data query is rewritten to select and reconcile each data record corresponding to the particular data record stored on the storage-class memory with the particular data record stored on a persistent data storage device of the computer.

摘要： Data within a database is partitioned into one or more sets of read-only data pages and one or more sets of append-only data pages, wherein each set of read-only data pages is associated to one of the one or more sets of append-only data pages. A repeated map is maintained for at least one of the one or more sets of append-only data pages. An operational position map is maintained for at least one of the one or more sets of append-only data pages. A request is received to update one or more records in a given set of read-only pages, wherein at least one of the one or more records comprises repeated values. The repeated map and operational position map of the append-only pages associated with the given set of read-only pages are updated in response to the request. The one or more sets of append-only pages are automatically merged with their respective set of read-only pages on a periodic basis to create one or more new sets of read-only pages.

摘要： Atomically updating shared data in a transactional memory system comprising transactional memory storage and a transactional memory enabled processor. The computer creates a pointer stored in a stable memory location that is used to locate a shared data stored in a second memory location. The computer accesses the shared data and loads the pointer used to locate the accessed shared data into transactional memory storage. The computer updates the accessed shared data using copy-on-write, whereby the updated shared data is stored in a third memory location, and performs the atomic update of the shared data by updating the pointer such that it locates the updated shared data stored in the third memory location.

摘要： Organizing data within a database is provided. In response to determining that a group of coarsified data records within a database table is not an aligned group of data records, a virtually replicated subgroup of coarsified data records that corresponds to the group of coarsified data records is generated from different groups of coarsified data records within the database table. The virtually replicated subgroup of coarsified data records is aligned with the corresponding group of coarsified data records.

摘要： Methods and a system are provided. A method includes maintaining an in-page log for records in each of a plurality of data pages of a multi-version database. The method further includes adding record update information to the in-page log when a corresponding one of the records is deleted or updated. The method also includes consulting the in-page log for a recently updated one of the records or a recently deleted one of the records to determine a record status thereof. The method additionally includes spilling, by a processor-based overflow manager, to overflow pages when the in-page log is full. The data pages include any of row-oriented data pages and column-oriented data pages.
