Crossing an OCEAN of queries: analyzing SQL query logs with OCEANLog

SQL queries encapsulate the knowledge of their authors about the usage of the queried data sources. This knowledge also contains aspects that cannot be inferred by analyzing the contents of the queried data sources alone. Due to the complexity of analytical SQL queries, specialized mechanisms are necessary to enable the user-friendly formulation of meta-queries over an existing query log. Currently existing approaches do not sufficiently consider syntactic and semantic aspects of queries along with contextual information. During our demonstration, conference participants learn how to use the latest release of OCEANLog, a framework for analyzing SQL query logs. Our demonstration encompasses several scenarios. Participants can explore an existing query log using domain-specific graph traversal expressions, set up continuous subscriptions for changes in the graph, create time-based visualizations of query results, configure an OCEANLog instance and learn how to choose a decide which specific graph database to use. We also provide them with access to the native meta-query mechanisms of a DBMS to further emphasize the benefits of our graph-based approach.
