Abstract: Solutions for enforcing both syntactic and semantic correctness of domain-specific data queries include: receiving a data query; constraining an operation of the data query to enforce semantic correctness, wherein enforcing semantic correctness comprises: determining semantic information associated with each of a plurality of data entities; based on at least the semantic information, determining whether combining the two data entities of the plurality of data entities is allowed or is not allowed; based on at least determining that combining the two data entities is allowed, permitting combining the two data entities in the data query; and based on at least determining that combining the two data entities is not allowed, preventing combining the two data entities in the data query; and executing the data query. Some examples further include basing the permission on (at least) an ontology between the semantic information of the two data entities and a set of axioms.

Abstract: Updating a staged dataset from a delta-based data repository is provided, including receiving an instruction to update the staged dataset based on a checkpoint and requesting a versioned subset of data from the repository based on the checkpoint and the received instruction. The versioned subset of the data includes a data differential between a staged version of the data stored in the repository and a checkpoint-based version of the data stored in the repository. The versioned subset of the data is received from the repository. The versioned subset of the data is incompatibly formatted for ingestion by a data analytics engine. The received versioned subset of the data is transformed into a staged subset of the data. The staged subset of the data is formatted for ingestion by a data analytics engine and stored in association with another staged subset of the data for ingestion by the data analytics engine.

Abstract: A data model metadata editor is described that may be integrated within a customer data platform. The editor enables a user to create and/or edit data model metadata by implementing a graphical user interface (GUI) that prompts the user to provide input and make selections in a manner that accords with rules concerning what information such metadata must include and how the contents of such metadata should be organized and formatted. Furthermore, the editor may perform syntax checking, validate such input and selections against the aforementioned rules, and flag any detected errors and/or potential problems to the user. Still further, the editor may apply the data model metadata (e.g., data schemas) to actual customer data and present the results to the user within the editor GUI so that the user can visually confirm that changes made to the data model metadata accord with the customer data.

Abstract: A simplified and accelerated determination of how much of a display element, generated by instructions executing on a computing device, is displayed is achieved through approximations based on a two-dimensional array whose dimensions are commensurate with a size of the display element. Each entry in the array is initialized to one binary value. If the display element is cut off by either physical display boundaries or by boundaries of a host display element, or if it is overlapped by another element, then the entries in the array corresponding to those portions of the display element that are not visible are changed to another binary value. Subsequently, the quantity of entries in the array having the original, initialized binary value, as compared with the total quantity of entries in the array, can provide an accurate approximation for how much of the display element was displayed.
