摘要： As part of a database system comprising a combination of on-disk storage and in-memory storage, a plurality of records that comprise a table are stored in a plurality of fragments that include at least a delta fragment and a main fragment retained in the on-disk storage. Each fragment has visibility data structures to enable multi-version concurrency control. Each fragment can be compressed using dictionary compression and n-bits compression. The fragments are loaded into main system memory in the in-memory storage from the on-disk storage if they are accessed for read operations or write operations and are not already in memory. A plurality of lockless read and write operations are concurrently performed, while providing snapshot isolation, on the at least one of the plurality of fragments while the at least one of the plurality of fragments is in the main system memory.

摘要： A database system supporting persistent queries, comprising a client software application, a persistent query service, and a plurality of network-attached data sources. On receiving a request to create a persistent query from the client software application, the persistent query service: creates a query virtual table; parses the persistent query; creates a plurality of intermediate virtual tables; establishes listeners for the query virtual table; creates a plurality of data source virtual tables; causes the plurality of data source virtual tables to retrieve initial data from data sources; and propagates data via intermediate virtual tables to the persistent query virtual table. On detection of a data change in a data source, the associated data source virtual table causes the data change to propagate via intermediate virtual tables to the persistent query virtual table, and the client software application executes client code of at least one listener.

摘要： Partially materialized views in the field of database systems are described herein. A method of partially materializing a view computed from one or more source tables comprises generating a view definition including a query expression and at least one control predicate referencing at least one control table. The query expression specifies the maximal content of the view, that is, the complete set of records that could be materialized. One or more control predicates and the contents of one or more control tables restrict what records are actually materialized and stored in the view. This allows the content of the partially materialized view to be adjusted simply by updating one or more control tables.

摘要： In some embodiments, a system for aggregating data stored in database tables may include a generator configured to generate a database view or a stored procedure for aggregating data stored in one or more database tables by replacing placeholders contained in one or more templates with dynamically determined names of the one or more database tables. The code structure of the table is free of a reference to a database name of at least one the one or more database tables whose data is to be aggregated in the report. The generation module is configured to store an SQL report command created as a result of the placeholder replacement in the database in the form of a view or a stored procedure.

摘要： Systems and methods for utilizing relation- and query-specific information to specialize DBMS code at runtime based on identifying runtime locally invariant variables. Runtime invariant is often of the form of variables in code that hold values that are constant during a portion of code execution. Micro-specialization is applied to eliminate from the original program unnecessary code such as branching statements that reference local invariant(s) in branch-condition evaluation. The resulting specialized code reduces the code complexity as well as significantly improves the runtime efficiency during code execution.
