A method, computer system, and a computer program product for mapping is provided. The present invention may include locating an asset using an unmanned vehicle (UV), where the asset include a sensor device that is not mapped to the asset. The present invention may also include recording, using the UV, a sensor identifier of the sensor device. The present invention may include recording a location of the sensor device based on determining a location of the UV when the sensor device is detected. The present invention may further include registering the recorded sensor identifier of the sensor device with the asset to map the sensor device to the asset.

A method, system, and computer program product for graph-based searching for one or more data streams is disclosed. A computer-implemented method comprises extracting a plurality of tuples from one or more data streams. The method further comprises generating a graph for the plurality of tuples in which a node represents a tuple of the plurality of tuples and an edge represents a correlation between the node and another node, and the edge is generated based at least partly on one or more predetermined queries for the one or more data streams. The method further comprises traversing the graph based on the one or more predetermined queries. Accordingly, embodiments of the present disclosure can improve the search speed by use of the graph-based searching for one or more data streams.

Graph-based searching for data stream

Methods, systems, and computer program products are provided. Tenant data of a multitenant relational database system is backed up by adding a value of a current version identifier for the tenant data to previous valid version identifiers for the tenant data, and changing the value of the current version identifier for the tenant data to a next previously-unused value. The tenant data is restored by changing the value of the current version identifier to a value of one of the previous valid version identifiers, and deleting, from the previous valid version identifiers, previous valid version identifiers that are not less recent than the changed value of the current version identifier. The tenant is provided with a view of the tenant data included in only a latest valid version of each respective record from among all valid versions of the each respective record.
