  • Patent number: 11914569
    Abstract: Systems, methods, and non-transitory computer readable media are provided for providing a redundancy tool for performing transactions. A transaction to be performed on a data stored in a database may be received. A timestamp may be assigned to the transaction. A lock may be assigned on the timestamp. The transaction may be performed on the data. The lock may be refreshed while performing the transaction on the data. A validity of the lock may be checked at after performing the transaction on the data. Responsive to the lock being valid, a result of performing the transaction on the data may be committed.

  • Patent number: 11914558
    Abstract: Systems and methods are provided in order to avoid ingesting the entire contents of one or more data sources. An object may be associated with one or more pieces/fragments of data that can be stored in different data sources. When a request for the object is initiated, a search for those pieces/fragments of data can be performed. Nodes associated with each data source may generate data queries appropriate for its corresponding data source, retrieve, and if needed transform the data into an object-based data structure. Any pieces/fragments of data that have been discovered and retrieved can be joined, e.g., by an application programming interface server, and forwarded to a requesting client or application. In this way, only data relevant to the object is obtained. Moreover, object versioning can be employed so that the most up-to-date data is obtained.

  • Patent number: 11907192
    Abstract: Systems and methods are provided for master-to-master OT-based artifact peering. A “master-to-master” architecture for artifacts is implemented in a network comprising a plurality of nodes and clients, where no node is designated a “master” or “primary” for a given artifact. A first node receives a subset of remote proposed operations from a second node and determines if a conflict exists between the received subset of remote proposed operations and at least one of a plurality of locally-proposed operations. The first node resolves the conflict based on a total-ordering agreed upon between the first node and the second node. The first node transforms at least one operation, either received or locally-proposed, based on the resolved conflict. The first node than updates a local log to include the transformed operation.

  • Patent number: 11789904
    Abstract: Systems and methods are provided for determining multiple fragments of data to be imported, the multiple fragments of data corresponding to different instances of data obtained from one or more external data sources, the different instances of data each corresponding to duplicate content. The multiple fragments of data that each correspond to different instances of duplicate content can be ingested. The multiple fragments of data can be de-duplicated to determine one or more corresponding object data source records (DSRs). The one or more object DSRs can be imported within a data platform system.

  • Publication number: 20220350575
    Abstract: A system may determine one or more data sources which the system is configured to access. The system may provide a set of application programming interfaces (APIs) for interacting with data stored in one or more data sources. The APIs may be accessible to one or more web applications which the system is configured to serve. The system may determine that a web application has requested an operation for interacting with the data through one or more APIs in the set of APIs. The system may determine one or more responses based at least in part on the operation requested by the web application. The system may provide the response(s) to the web application.

  • Patent number: 11275753
    Abstract: Various systems and methods are provided that display schematics and data associated with the various physical components in the schematics in an interactive user interface. For example, a computing device links data stored in one or more databases with schematics displayed in one or more interactive user interfaces. The computing device parses a digital image that depicts a schematic and identifies text visible in the digital image. Based on the identified text, the computing device recognizes representations of one or more physical components in the schematic and links the representations to data regarding the physical component in one or more databases, such as specification data, historical sensor data of the component, etc. The computing device modifies the digital image such that it becomes interactive and visible in a user interface in a manner that allows the user to select a physical component and view data associated with the selection.
