在此四元组模型的基础上，应用面向对象设计的思想，结合跳跃表、动态空间管理、编译预处理等技术方法，构造出一个单片机软件仿真器类群。
With the theory of object-oriented design, jump table, dynamic memory management and code pre-processing, the class group of software simulators for single-chip microcomputers are designed.
对于多索引下推，多索引扫描用于组合来自不同索引扫描的RID，然后就可以执行对事实表的跳跃式扫描了。
For multiple index push-downs, multi-index scan is used to combine RIDs from different index scans, then skip-scan on the fact table is performed.
Time维度表中满足过滤条件的 time_id连接键被散列以创建一个位向量，用于过滤以上跳跃式扫描的Orders 表行。
The time_id join keys that meet the filter requirements on the Time dimension table are hashed to create a bit vector that filters rows of the Orders table from the skip scan above.
检索到的RID被分类并用于跳跃式地读取orders表。
The retrieved RIDs are sorted and used to read the Orders table in a skip scan.
检索到的RID被分类并用于跳跃式地读取orders表。
The retrieved RIDs are sorted and used to read the Orders table in a skip scan.
