摘要： Techniques are presented for generating semantic layers that are used to facilitate data analyses of subject datasets. The semantic layers are generated from data analysis configurations that characterize analysis environments pertaining to the subject datasets rather than from subject dataset metadata that is associated with the subject datasets. Data analysis attributes are extracted from configuration content objects that codify the data analysis configurations. A set of rules are accessed to facilitate mapping of the data analysis attributes to semantic model metadata that constitute the semantic layers. Some of the generated semantic layers comprise virtual data models. The virtual data models and/or recommendations associated with implementation of the semantic layers are presented to users. Certain portions of the semantic layers and/or the configuration content objects may be modified (e.g., in accordance with the implementation recommendations) to facilitate use of the semantic layers when performing data analyses of the subject datasets.

摘要： The present disclosure provides a detailed description of techniques used in systems, methods, and in computer program products for dynamic aggregate generation and updating for high performance querying of large datasets. Certain embodiments are directed to technological solutions for determining at least one aggregate of selected virtual cube attributes (e.g., measures, dimensions, etc.) describing a virtual multidimensional data model of a subject database, and generating an aggregate table and a set of aggregate metadata for the aggregate. In some embodiments, an aggregate database statement configured to operate on the subject database can be issued to generate the aggregate table and/or aggregate metadata. Further, the aggregate can be dynamically determined responsive to receiving a database statement configured to operate on the virtual multidimensional data model representing the subject database. The aggregate table can comprise one or more partitions in an aggregate view to facilitate aggregate management and/or quality.

摘要： The present disclosure provides a detailed description of techniques for data model design collaboration using semantically correct collaborative objects. Certain embodiments comprise detecting various interaction events from designers collaborating on designing a virtual multidimensional data model to generate unit of work objects characterizing certain design transactions invoked by the interaction events. The unit of work objects are used to determine a set of committed modifications to the virtual multidimensional data model design for broadcasting to the collaborating designers. Some embodiments comprise unit of work objects based on various multidimensional data model rules, syntactic rules, semantic rules, and/or other criteria to determine valid committed modifications. Other embodiments comprise unit of work objects from multiple design transactions that are merged to determine the committed modifications. Further embodiments comprise committed modifications that are derived from the differences between the design changes and the then current virtual multidimensional data model.

摘要： A query syntax analysis and postprocessing system and method receives a query request specifying values of a data type directed to a database without native support for the queried data type. A query engine or process for receiving a query request defined by a query syntax traverses the query request for a specification of an unsupported value or expression. In a large, distributed database environment, the query request may implicate multiple physical data stores, each having specific formats and recognized syntax. Values of unsupported or non-native types, or expressions that evaluate to an unsupported or non-native type, are identified and replaced with an expression that is recognized by the legacy database.

摘要： A hybrid code construct combines imperative and declarative semantics for leveraging complementary features for a relational database exchange optimized for declarative access driven by imperative direction for imposing iterative and conditional looping behavior. Databases responsive to a declarative command structure receive declarative code generated from an imperative code sequence. The imperative code is based on a language that allows conditional iteration for repetitive commands, which invoke the declarative command syntax within a controlled loop or iteration. Declarative syntax, while enjoying optimizations for high performance database access, does not lend itself well to iterative logic common for linear regression and training of ML models. The hybrid code allows efficient ML training while the dataset defining the model remains within the database and need not incur network transport for Al based usage.

摘要： A network device for enforcing an authorization policy to a database includes identifying an authorization policy based on declarative designations of a set of objects, subjects and actions affected by an access request, and distributing the executable entity to a plurality if endpoints of a network of users. Each endpoint of the plurality of endpoints has one or more client applications. The endpoint embeds the executable entity in the client application, the executable entity responsive to access requests from the client application, and the endpoint node grants the access request based on evaluating the access request against the authorization policy, evaluating based only on instructions in the executable entity.

摘要： A multidimensional database query engine processes a query request by forming a logical plan of subqueries for retrieving and assembling the data called for by the query request. A multi-pass analysis identifies a granularity of facts needed to fulfill the query request. A recursive analysis parses the query request and identifies components comprising the full query request. The analysis derives a subquery from each component, and identifies dependencies on other subqueries. The subqueries are arranged in a tree structure based on the dependencies. The tree represents subqueries as nodes, with query operations denoted by parent nodes for the dependent subqueries. The result is a hierarchical tree of subqueries associated based on operations between the subqueries and dependent subqueries descending from their parent subqueries.

摘要： Techniques are presented for efficiently provisioning application-agnostic resource access to a variety of applications without modification to the native access control mechanisms of the applications and without transmission of a user's credentials over the network. A user of an application is authenticated by an authorization provider. An access token for the authenticated user is generated. A session password is generated based at least in part on the access token. The session password is applied by the user to the native access control mechanism of an application to facilitate access to resources (e.g., set of subject data) by the application. The resource access is achieved without modification to the native access control mechanism of the application and without transmission of the credentials (e.g., username, password, etc.) of the user over the network.
