摘要： In column domain dictionary compression, column values in one or more columns are tokenized by a single dictionary. The domain of the dictionary is the entire set of columns. A dictionary may not only map a token to a tokenized value, but also to a count (“token count”) of the number of occurrences of the token and corresponding tokenized value in the dictionary's domain. Such information may be used to compute queries on the base table.

摘要： Clients are permitted to directly attach to a client server system. An oplog management system tracks changes as clients make the changes to control structures of the direct connection client server system. The Oplogging system stores changes in oplogs. Then, if a client fails, the Oplogging system can repair the control structures, either by undoing the changes made by the client, or else completing the changes in place of the client; depending upon principles defined.
摘要翻译： 允许客户端直接连接到客户端服务器系统。 当客户端进行更改以控制直接连接客户端服务器系统的结构时，Oplog管理系统跟踪更改。 Oplogging系统存储oplogs中的更改。 然后，如果客户端失败，则Oplogging系统可以通过撤销客户端所做的更改来修复控制结构，也可以修改客户端的更改; 取决于所定义的原则。

摘要： A two copy versioning scheme is proposed. The scheme provides efficient implementation for a high read load database and eliminates read dependencies. The versioning scheme provides efficient implementation for transactions executing under ANSI READ COMMITTED isolation, and is extensible to serializable isolation. The two-copy versioning scheme is garbage free meaning that all versions of data records are used during execution and is adapted to index scanning operations. A “deferred delete” scheme allows read transactions to complete data deallocation operations. Statements that require “snapshots” are efficiently supported.
摘要翻译： 提出了一种双重版本控制方案。 该方案为高读取数据库提供了有效的实现，并消除了读取依赖关系。 版本控制方案为在ANSI READ COMMITTED隔离下执行的事务提供了有效的实现，并且可扩展到可序列化隔离。 双副本版本控制方案是无意义的，意味着在执行期间使用所有版本的数据记录，并适应于索引扫描操作。 “延迟删除”方案允许读取事务完成数据解除分配操作。 有效地支持需要“快照”的语句。

摘要： New lock modes are based on the concept of neighborhoods and are applied to spaces in indexes. The new lock modes include a Read, or shared, neighborhood (Snei) lock mode and a Write neighborhood (Xnei) that enhance concurrency among non-serializable transactions.
