    Abstract: The systems, methods, devices, and non-transitory media of the various embodiments enable query execution plan graphs to be compared to determine whether all or portions of two or more queries define data sets that are structurally equivalent. Two data sets may be structurally equivalent when each data set may be composed with a bijective relation that yields the other. In the various embodiments, when all or a portion of a first query that has been previously run defines a data set that is structurally equivalent to a data set defined by all or a portion of a second query that is to be run, the structure preserving transform may be applied to the corresponding portion of the second query to transform that portion of the second query into the corresponding portion of the first query, thereby allowing the results from previously running the first query to be reused.

    Abstract: A data management device (10) is provided, comprising a control module (100) and a storage module (1 10), wherein the storage module (1 10) is configured to store a plurality of data sets in a plurality of data set groups such that the plurality of data sets is assigned to the plurality of data set groups such that every data set group comprises at least one data set and every data set is stored in one data set group only and wherein the control module (100) is configured to assign an exclusive execution context to each data set group and to estimate a number of data set requests for every data set. The control module (100) is further configured to determine data sets for every data set group based on the estimated number of data set requests and to reassign the data sets to the data set groups such that the estimated number of data set requests in a data set group is less or equal to a predetermined number of data set requests for at least one exclusive execution context which is assigned to one of the plurality of data set groups. Thus, skew workload of the data set groups and the assigned exclusive execution contexts can be avoided.

    Abstract: A parent record is created, and the parent record includes a cache for children. Child records are created, and each child record belongs to a parent. Responsive to the creation or update of a child record, the parent record's cache is invalidated. To rebuild the parent record's cache, the child records are serialized and written into the parent record's cache. During a read operation, the parent record is read, including the parent record's cache of children, in a single database access. This results in a substantial savings of time as compared to retrieving the parent and the children from the database separately. Where the number of reads of the parent record greatly exceeds the number of changes to child records, serialized child associations in parent records enhances the efficiency of database access.

    Abstract translation: 父记录被创建,并且父记录包括儿童缓存。 创建子记录,并且每个子记录属于父级。 响应于创建或更新子记录,父记录的缓存无效。 要重建父记录的缓存,子记录被序列化并写入父记录的缓存。 在读取操作期间,父记录在单个数据库访问中被读取,包括父记录的子级缓存。 与从数据库中单独检索父级和子级相比,这样可以大大节省时间。 如果父记录的读取次数大大超过对子记录的更改次数,父记录中的序列化子关联可提高数据库访问的效率。

    Abstract: A consistent user view system. The system incorporates any changes made by a user in any views shown to that user even when the changes have not propagated to the partitions supplying the view. The system separates the authority for edits from the replicated storage allowing efficient transactions and linear scalability. Documents are read from view-based partitions of a store. Document writes are written to a document-specific partition in a journal and applied to the store. The system stores a copy of pending changes in a user-specific partition. When a user requests a view, the system checks that user's cache for any pending changes applicable to the view. If any applicable changes are found, the changes are applied before showing the view to the user. Pending changes that have been successfully applied to the store are trimmed from the user-specific partition to free up resources.

    Abstract: A system, method, and non-transitory computer readable medium for retrieving data in response to an input query is provided. The system includes a first data server configured to generate a query based on the input query and a second data server configured to generate a another query based on the input query. The system also includes a master server in communication with the data servers. The method involves generating queries based on the input query and sending the queries to data sources. The method also involves determining if data records represent the same external entity and combining data records to store. The non-transitory computer readable medium is encoded with codes to direct a processor to carry out the method.
