Abstract: An application may support ingestion of data to a data server. A user may identify the data source, and the server may determine a connector corresponding to the identified data source. The server may support a plurality of connectors for data ingestion. Based on the selected source, the user may select a data channel type, where the data channel type is associated with one or more packaged data sets that include different data set types. The server may then ingest the data set using the determined connector. The application may further support mapping of source and target attributes, custom mapping, and transformation functions.

Abstract: In the present disclosure, systems and methods are described for allowing a non-code user to create to transform a database in an ETL pipleline. Specifically, as disclosed herein, a user can take a database and receive a ruleset to apply to the database in an ETL pipeline. The data linting system may take the database and extract a schema and a data sample from it. Further, the data linting system may use the schema and data sample to create two rulesets. With these rulesets, the data linting system combines them to create a final ruleset which may be validated using the data sample. The data linting system then sends the final ruleset and the validation report to the user. With this system, the user only needs to give it a database and will receive a ruleset that is able to be immediately used in an ETL pipeline.

Abstract: A data server may support segment identification based on a selected user profile. For example, a user may select a user profile as the basis for identifying a segment of additional user profiles. The server may identify attributes associated with the selected user identifier and generate an expression based on the identified subset. The expression may include a normalization function corresponding to at least one attribute. The normalization function may identify correlated attribute values for an attribute associated with the selected user profile. The data server may query a data storage system to identify the additional user profiles based on the expression. The data server may also support user defined Boolean expressions such that the expression is used to identify user identifiers associated with a first attribute and a second attribute.

Abstract: An identity authenticator receives a first authentication credential from a first application at a first computing device. The identity authenticator then determines that the first authentication credential is associated with a second authentication credential for the first application at a second computing device based on a stored authentication identity. The identity authenticator then provides a stored execution state for the first application to the first computing device, wherein the stored execution state is associated, based on the stored authentication identity, with at least one of the first authentication credential or the second authentication credential.

Abstract: Methods, systems, and devices are described that support extensible data mapping. A data mapping server may receive an indication of a source schema for a data source and may receive a user input indicating creation of a custom data object to handle the source schema. The server may create the custom data object based on the user input. The data mapping server may automatically map one or more data fields for a source data object (e.g., based on the source schema) to one or more custom data fields for the custom data object (e.g., based on a custom schema). The server may import a set of data records stored at the data source and may store the data records in a database system according to the custom schema based on the data mapping. The stored custom data objects may be used for segmentation, activation, analysis, or some combination thereof.

Abstract: A method for data processing includes identifying, for communication of a content object, a segment of entities based at least in part on a selection of a first attribute at a user interface. The first attribute may be selected from attributes defined by a data model and configured for a tenant of a multi-tenant system. The method further includes activating a set of attributes of the plurality of attributes based at least in part on the identified segment of entities and the data model. The method further includes, receiving a selection of a second attribute of the set of attributes, identifying, for the segment of entities, a set of inputs corresponding to the selected second attribute, and transmitting, to a content communication system for distribution of the content object, an indication of a plurality of entity identifiers corresponding to the segment of entities and the set of inputs.

Abstract: A method for data processing includes displaying, at a user interface, a plurality of attributes that are defined by a data model configured for a tenant of a multi-tenant system. The plurality of attributes includes a one-to-many attribute that is configured to support multiple inputs and a direct attribute configured to support a single input. The method may further include receiving a selection of a first one-to-many attribute for defining an expression for identifying a segment of entities. The method may further include activating, for selection at the user interface, a subset of the attributes based on each attribute of the subset being dependent on the first attribute. The method may further include receiving an indication of the expression, executing a database query to identify the segment of entities, and transmitting, to a content communication system, an indication of the segment of entities.

Abstract: Techniques discussed herein describe an example system for verifying the identity and location of a customer in a bank branch parking lot. A server determines whether to provision a service for a vehicle based on telemetry data received from a telemetry module on the vehicle in a fleet of vehicles. The telemetry data includes a first location and status information of the vehicle. The server identifies a vendor to provide the service and directs the vehicle to a second location of the vendor from the first location of the vehicle. The server provides authorization to the vehicle for an on-board transaction module to initiate a request for the service when the vehicle is at the second location of the vendor.

Abstract: An example method of live migration of distributed databases may include implementing a first database access mode with respect to a distributed database to be migrated from an original set of storage servers to a destination set of storage servers, wherein, in the first database access mode, database read requests are routed to the original set of storage servers and database update requests are routed to both the original set of storage servers and the destination set of storage servers. The method may further include copying a plurality of records of the distributed database from the original set of storage servers to the destination set of storage servers. The method may further include switching to a second database access mode, in which database read requests are routed to the destination set of storage servers and database update requests are routed to both the original set of storage servers and the destination set of storage servers.
