As the name implies, an in-memory database resides entirely in main memory rather than on disk, making data access an order of magnitude faster than with conventional, disk-based databases.
顾名思义，内存中数据库完全驻留在主存中，而不是磁盘上，这使得数据访问比传统的基于磁盘的数据块要快一个数量级。
When data are contiguous, the time used to access data on the disk is minimized and the database server can read data faster.
当数据连续时，用于访问磁盘上数据的时间最少，数据库服务器可以更快地读取数据。
The obvious advantage of this scenario is reduced database calls and therefore reduced transaction load and faster access to objects in the grid.
这一方式具备的明显优势就是能够减少数据库调用，从而减少事务负载，更快地访问网格（grid）中的对象。
