Using these data sets, we can get the work items and their structures.

使用这些数据集，我们可以得到工作项目和它们的结构。

For example, if you manage data in hash tables or other unordered data structures in the application domain, you might face additional work re-assembling elements into the order set by a schema.

比方说，如果在应用领域采用哈希表或者其他无序数据结构管理数据，可能会面临着将元素按照模式中的顺序设定重新装配的额外工作。

For example, data structures and access methods are specifically optimized to work on data that is located in main memory.

比如，数据结构和访问方法专门针对位于主内存中的数据进行了优化。

The Doppler effect (familiar from the changing pitch of a passing police siren) gives away the velocities of these particles and Dr Haller's computers are able to crunch the resulting data in the light of Lagrange's theories and work out the network of coherent structures that is causing their movements and the pattern of updraughts and downdraughts that should result.
