(这个阶段将把XML结构的数据转换成表结构数据)。

This stage will transform the hierarchical XML data about accounts into a tabular result structure.

此外，通过使用行业标准的“星型模式”(star schema)而不是更规范化的表结构，数据仓库经过了优化以实现高效的查询和快速的响应时间。

In addition, by using an industry standard "star schema", rather than a more normalized table structure, the data warehouse is optimized for efficient queries and quick response times.

现在我们必须在数据库中创建表结构，这也会清除现有表和数据(如果有的话)，并从头开始。

Now we must create the table structure in the database, which also wipes out the existing tables and data (if there's any) and start from scratch.

For those perhaps familiar with some of the jargon do we introduce what we call link lists and hash tables and tries, increasingly sophisticated data structures, that allow us to solve problems that are much bigger and much more interesting than the very familiar one that we started with here.

那些对编程的术语较熟悉的同学,我们会教授,链接列表，哈希表，以及日益复杂的数据结构,以便帮助我们解决其他的,比现在所学的更大也更有趣的问题。
