摘要： A query is received by a database server from a remote application server. The query is associated with a calculation scenario that defines a data flow model that includes one or more nodes that each define one or more operations for execution by a calculation engine on the database server. Thereafter, the database server instantiates a runtime model of the calculation scenario based on the nodes of the instantiated calculation scenario. Subsequently, one or more of the nodes are identified as being convertible into a relational database format. These nodes are then used to form a container node. An execution plan of the runtime model of the calculation scenario including the container node is built that is executed by the database server to result in a data set which is provided by the database server to the application server.

摘要： Embodiments relate to re-writing database query plans, and visualizing such re-written query plans. A query re-write framework includes a query normalization engine in communication with a rule catalog comprising query re-write rules in the form of rule classes. The framework receives as input, a query plan graph to be re-written. Based upon the engine's application of re-write rules from the catalog, the framework produces a re-written query plan graph as output. An interface component of the framework may provide a visualization of the re-written query plan graph as part of a dashboard. A user may access the framework to enable/disable existing rules in the catalog, add new rules to the catalog, and/or control a sequence and a precedence in which rules are applied to re-write the query plan. A user may interact with the visualization of the re-written query plan for purposes of de-bugging, re-write optimization, and/or query development.

摘要： A hybrid database table is stored as both a row and a column store. One or more techniques may be employed alone or in combination to enhance performance of the hybrid table by regulating access to, and/or the size of, the processing-intensive column store data. For example during an insert operation, the column store data may be searched for a uniqueness violation only after certain filtering and/or boundary conditions have been considered. In another technique, a hybrid table manager may control movement of data to the column store based upon considerations such as frequency of access, or underlying business logic. In still another technique, querying of the hybrid table may result in a search of the column store data only after an initial search of row store data fails to return a result.

摘要： A computer system affords a user the ability to interactively formulate, visualize, and modify query plans that are to be posed to a database. The computer system provides query visualization in the form of decision trees having nodes selectable/deselectable to search for alternative query plans with lower or minimum execution time. The estimated cost and/or the execution time of a subtree of a query plan may be mapped according to a rectangle area metaphore, with the area of a rectangle enclosed by a larger rectangle representing a parent node in the plan tree. Query plans may be saved by the system in order to facilitate their visualization, optimization, and/or modification at a later date.
