  • Publication number: 20210064694
    Abstract: This application discloses a computing system implementing a management system to generate a presentation populated with a portion of a meta model in response to a meta model access request for a first client device. The presentation includes one or more editable fields capable of data entry by the first client device. The management system receives an indication that the first client device utilized at least one of the editable fields of the presentation to initiate a modification to the portion of the meta model, and locks a second client device from modifying the portion of the meta model. When the first client device completes the modification to the portion of the meta model, the management system updates the portion of the meta model based on the modification to the portion of the meta model and unlocks the second client device from modifying the portion of the meta model.

  • Publication number: 20210064615
    Abstract: This application discloses a server configured to receive an expanding memory access request for nested data stored in a memory system having multiple relational tables. The expanding memory access request identifies the relational tables storing the nested data and has a syntax that indicates links between the relational tables storing the nested data. The server parses the expanding memory access request to identify the links between the relational tables that store the nested data, and generates memory access commands based on the identified links. The memory access commands, when provided to the memory system, prompt the memory system to retrieve the nested data from the relational tables for the server. The server generates a response message that includes the nested data in a format specified in the expanding memory access request and transmits the response message to a client device that issued the expanding memory access request to the server.

  • Patent number: 5999911
    Abstract: A workflow manager system provides computer-assisted, graphical tools for defining and managing complex processes in terms of a workflow. A workflow includes a number of steps having step encapsulations and dependency relationships. Step encapsulations define the work to be performed by a step in a work flow such as launching a design tool. The dependency relationships represent the conditions that must be satisfied before a step can be performed and can be expressed in terms of boolean relationships using step and data states or data values as arguments. The workflow system manages the state of a workflow including the state of steps and data, and makes the workflow and its related data accessible to multiple users.
