Abstract: In an approach for migrating database content with row-level security from a source database with row-level security to a target database without row-level security, a computer determines a type of the source database to be migrated, and upon determining that a source table of the source database is maintained using multi-level security attributes, creating a data structure for a source table of the source database for storing meta-data comprising the multi-level security attributes, determining all dimensions of the multi-level security attributes, adding columns to a target table of the target database relating to the source table, the added columns representing the multi-level security attributes of the source table.

Abstract: A computer-implemented method for processing a query for accessing data in a database with row level security may be provided. The data is organized in rows and columns, and the rows are grouped in storage regions. The method comprises maintaining, as part of a control record for each storage region, a lower access security label, representing a minimal user access right of any of the rows in the storage region, and an upper access security label representing a maximal user access right of any of the rows in the storage region, and upon determining, for a query, whether an access right of a user initiating the query is below the lower access security label of a storage region addressed by the query, skipping the storage region during a read execution of the query.

Abstract: The present disclosure relates to a method for recording user activity on a computer. The method includes creating a video file for a video sequence of a user interface of an application of the computer. Video frames may be recorded in the video file, wherein a video frame comprises data indicative of the visual representation of the user interface and corresponding timestamp, wherein the data of the video frame is parsable.

Abstract: An embodiment is directed to a method for analyzing a computer program that includes receiving an instruction specifying a first variable of the program. The first variable has a first value at a first location during program execution. The instruction further specifies a second value for the first variable at the first location. The method includes determining that a second location during program execution includes a conditional control flow instruction that includes the first variable. In addition, the method includes evaluating the conditional control flow instruction using the first and second values of the first variable at the second location. It may be determined whether control flow diverges at the second location based on the evaluating of the conditional control flow instruction using the first and second values at the second location.

Abstract: A method, system, and computer program product for merging monitoring data streams includes: receiving a first monitoring data stream relating to a server containing first records, each first record has a first transaction identifier relating to a first transaction and first monitoring data, relating to a performance of executing the first transaction; receiving a second monitoring data stream relating to a client containing second records, each second record has a list of second transaction identifiers relating to one or more second transactions and second monitoring data, relating to a performance of executing the second transactions; buffering at least parts of the first and the second monitoring data streams; and merging the buffered first and second monitoring data streams by computing an outer-join with a join-condition that the first records have the first transaction identifier that occurs in the list of second transaction identifiers to provide a merged data stream.
