A method, computer system, and a computer program product for propagating a recording are provided. A recording is received from a user computer. The received recording is analyzed. In response to determining based upon the analysis of the received recording that at least a portion of the recording is suitable for propagation, the portion of the recording is transmitted to a venue for playing of the portion. In response to the transmitting of the portion of the recording, a confirmation message is transmitted to the user computer.

Systems and methods are provided to generate context-based questions from communications data. In embodiments, a method includes: determining, by a processor set, context of text under study obtained from digital communications data; generating, by the processor set, a text-based summary of the text under study using a natural language processing (NLP) tool to eliminate text from the text under study based on keywords of a dynamic knowledge base; constructing, by the processor set, a question phrase in sentence form based statements in the text under study, wherein the one or more statements constitute an answer to the question phrase; outputting, by the processor set, a question and answer set including the question phrase and the statements; and automatically updating, by the processor set, the dynamic knowledge base based on the question and answer set, thereby generating an updated dynamic knowledge base.

An embodiment for recommending routes in an enhanced navigation system is provided. The embodiment may include receiving a destination from a primary user. The embodiment may also include obtaining a tentative list of routes. The embodiment may further include identifying each user and characteristics associated with each user. The embodiment may also include analyzing current conditions of the tentative list of routes and the characteristics. The embodiment may further include identifying one or more optimal routes. The embodiment may also include recommending the one or more optimal routes to the primary user. The embodiment may further include in response to determining the primary user selects an optimal route of the one or more optimal routes, presenting the selected optimal route on a navigation display to the primary user.

A computer-implemented method includes writing a plurality of change records to a first set of redo records in a first transaction log file. The computer-implemented method further includes determining, while writing a change record to a redo record, that the change record includes changes made to data associated with an in-scope table. The computer-implemented method further includes updating the first transaction log file with information indicating that the redo record includes changes made to data associated with the in-scope table. The computer-implemented method further includes accessing the first transaction log file from storage in response to receiving a request for replicating changes made to data associated with in-scope tables. The computer-implemented method further includes scraping a first redo record in the first transaction log file in response to determining that the first redo record includes at least one change record associated with the in-scope table.

Asynchronous replication of in-scope table data

A dynamically self-indexing database-management system selects database indexes associated with table columns that are most frequently accessed by user queries, deleting all other indexes. The system periodically reviews database-performance figures and data-usage patterns for each table of its database and revises its selection of indexes in order to ensure that only the most frequently accessed columns continue to be indexed and that the omission of other indexes does not degrade performance. The total number of selected indexes, the overall percent of selected indexes, or the selection itself is optimized over time through continued monitoring of database transaction logs. Optimization may comprise cognitive analytics or other methods of artificial intelligence by which the system learns over time how to best determine whether its current selection of indexes is likely to provide the best overall performance.
