Abstract: A join operation between split data tables includes providing reduction data from first partitions to each partition among second partitions. The reduction data serves to identify actual values in one of the second partitions that also occur in one of the first partitions. Global IDs are assigned. Translation lists including the global IDs are sent to the first partitions. Each first partition and each second partition create globalized lists which can then be combined to generate respective first and second compiled lists. The join operation can then be conducted on the first and second compiled lists.

Abstract: String comparison, including comparing strings with a rule, can be time consuming, and strings may not be suitable for analysis using machine learning algorithms. The present disclosure provides positionally-encoded representations of strings, such as binary matrices or arrays, that provide an encoded representation of the string. The encoding, and decoding, can be facilitated by an encoding schema, such as an encoding schema stored in the memory of a computer device. The encoding schema associates particular characters with particular positions in an array. The positionally-encoded string representations can be used for security applications, such as to determine whether an authorization token that includes at least one string complies with an authorization rule. The authorization rule can be specified as a positionally-encoded representation that defines a set of strings that comply with the rule.

Abstract: Various embodiments of systems and methods for detecting database blocking are described herein. The method includes detecting a non-responding state of an application. Once the non-responding state is detected, a request is sent to a database to retrieve blocking information related to the application. The blocking information is received from the database. The blocking information indicates whether the non-responding state of the application is due to database blocking or other issues. When the non-responding state is detected due to the database blocking, the blocking information also indicates whether the application is a victim or the application is a root blocker. When the application is the victim, one or more IDs and contact information related to the root blocker is provided to resolve database blocking, e.g., by discussion. When the application is the root blocker, IDs and contact information related to one or more victims of the application is provided.

Abstract: A method for providing a visual representation of data stored in a database may include generating a graphic user interface configured to receive inputs for constructing a hierarchical measure based on the data stored in the database. An indication to add, to the hierarchical measure, a first measure and a second measure may be received via the graphic user interface. In response to the indication, the hierarchical measure may be constructed to include, based on the first measure being added prior to the second measure, the first measure as a parent measure and the second measure as a child measure. A first value of the first measure may correspond to an aggregate of at least a second value of the second measure. The graphic user interface may be updated to provide a visual representation of the hierarchical measure. Related systems and articles of manufacture are also provided.

Abstract: An information collection module receives an incident report request from a user of a browser running a network application on a client system to thereby provide a page in the browser. The information collection module collects incident data including user interactions with the page, client system features and operations associated with executing the network application, and a document object model (DOM) of the page. An annotation tool of the network application receives annotations of the page from the user for inclusion in the incident data, and a server-side incident manager receives the incident data. The server-side incident manager includes a rendering engine that renders the document object model and the annotations, and an incident analyzer that displays the collected user interactions, and client system features and operations, and the rendered document object model and annotations.

A set of data associated with the interaction is determined which includes an identification of each field associated with the identified interaction and a count of a number of interactions associated with each particular field. A relevancy index table is updated to include the determined set of data, wherein each identified field is associated with a row in the index table. At least one relevancy rule is identified for the relevancy index table and is executed to generate a relevancy score for at least one of the fields.

Abstract: A computer implemented method for extended monitoring of a database includes establishing a data virtualization communications connection between a first and a second datacenter that is a copy of the first datacenter. Requests for monitoring information corresponding to the first datacenter are made by accessing its system views. Requests for monitoring information corresponding to the second datacenter are made by generating virtual tables on the first datacenter to provide the system views of the second datacenter to the first datacenter and accessing the virtual tables. The monitoring information corresponding to the first datacenter is grouped into a first schema on the first datacenter and the monitoring information corresponding to the second datacenter is grouped into a second schema, separate from the first schema. A union view is generated by combining the monitoring data associated with the two datacenters. Related apparatus, systems, techniques and articles are also described.
