Abstract: A database manager is disclosed that retrieves database records having binary encoded data from a database and instantiating objects in an in-memory database. Binary encoding compresses data, allowing many subrecords to be stored a single blob field of a database record. Retrieving chunks from storage reduces transfer time by reducing the size of data and the number of operations needed to retrieve all the subrecords. The database manager receives database access requests from a database application. Changes made to the database objects and committed by the application are written back to the persistent database as versioned delta records. In a subsequent session, loading the database from storage includes first loading the most recent snapshot record, then applying changes to the data stored in delta records. The changes stored in the delta records are applied to the data in the snapshot record in the order in which they were made.

Abstract: A data hierarchy including individual data nodes may be used to represent a wide variety of data collections. Requests to change or add nodes in the data hierarchy may be received from many different sources over time. Instead of considering these change requests individually, an interface allows a plurality of change requests to be consolidated together into a single consolidated request. The consolidated request may be displayed in an interface such that changes from each of the original requests may be displayed together in an interface so that a cumulative effect of each of the change requests may be considered before the data changes are committed to the underlying data structure. The consolidated request may maintain links and update underlying data objects representing each of the original requests to provide a record of actions related to the consolidated request.

Abstract: Techniques for managing requests to modify a data set at future times are disclosed. The system receives a request to modify the data set at a future time, such as in a future time window. The system generates a representation of the data set at the future time. The system determines the future state of the data set based on the current state of the data set and requested future modifications to the data set. The system determines whether a conflict exists between the request to modify the data set at the future time and another scheduled request to modify the data set at the future time. Based on determining whether a conflict exists, the system performs one or more of scheduling the request to modify the data set at the future time and performing a remediation action to address the conflict.

Abstract: A method is provided for testing two port memory. The method includes receiving a synchronous write through (SWT) mode signal that indicates one of a functional mode of operation and a testing mode of operation of the memory, wherein the testing mode triggers bypassing of one or more read operations from bit cells of the memory identified by read address signals, and switching between the functional and testing modes of operation in dependence on the SWT mode signal. When the memory is in the testing mode of operation the circuit, receiving test data obtained from read address signals to represent a test state for the bit cells of the memory.

Abstract: Techniques for modifying hierarchal-structured data of one hierarchal data structure based on a modification to another hierarchal data structure are disclosed. A system determines that a modification has been made, or is requested to be made, to a particular hierarchal data structure. The system analyzes a set of rules to determine whether the modification of the hierarchal data structure triggers another modification to an additional hierarchal data structure. The additional hierarchal data structure includes different nodes, or nodes arranged in a different hierarchal structure, than the particular hierarchal data structure. The system modifies the additional hierarchal data structure based on the rule. The modification of the additional hierarchal data structure is different than the modification to the particular hierarchal data structure.

Abstract: A memory device includes clock signal generation circuitry, and first integrated level shifter and latch circuitry. The clock signal generation circuitry receives a first clock signal and an isolation signal, and generates a second clock signal based on the first clock signal and the isolation signal. The isolation signal corresponds to a power state of a power supply associated with the first clock signal. The first integrated level shifter and latch circuitry receives an input signal in a first power supply domain, and latches a value the input signal based on the second clock signal. Further, the first integrated level shifter and latch circuitry outputs, based on the latched value, an output signal in a second power supply domain different than the first power supply domain.

Abstract: Techniques for modifying a query based on a data index of nodes in a data set are disclosed. A system modifies queries based on query terms associated with indexed data. The system modifies queries to include query terms based on indexed data or to obtain values for query terms that are not associated with indexed node properties. The system adds query terms, that reference indexed data, to a query in response to determining that none of a query's terms reference indexed data. The system derives values for query terms that are not associated with indexed node properties using a logical or mathematical formula. The system traverses parent nodes of a child node to identify values for query terms that are not associated with the child node in a data index, but are inherited from a parent node.
