如何使XML配置文件和數據庫表之間的值保持同步？

Question

我正在按層次結構分層構建。 舉個例子。

Category 7
    Objective 7.1  [GeneralExpectation='']
        A  [Expectation='']
        B  [Expectation='']
        C  [Expectation='']
    Objective 7.2  [GeneralExpectation='']
        A  [Expectation='']
        B  [Expectation='']
    Objective 7.3  [GeneralExpectation='']
        A  [Expectation='']
Category 8
    ...

我想將這些信息存儲在xml文件而不是數據庫中會很方便。

<Levels>
  <Level Id=7>
    <Categories>
      <Category Id=1 Name="Numbers, Operations, and Quantitative Reasoning" Expectation="The student will demonstrate an understanding of numbers, operations, and quantitative reasoning.">
        <Objective Id="7.1" Name="Number, operation, and quantitative reasoning." GeneralExpectation="The student represents and uses numbers in a variety of equivalent forms. The student is expected to">
          <SubObjective Id="A" Expectation="compare and order integers and positive rational numbers; Supporting Standard" />
          <SubObjective Id="B" Expectation="convert between fractions, decimals, whole numbers, and percents mentally, on paper, [or with a calculator]; and Readiness Standard" />
        </Objective>
      </Category>
      <Category Id=2 Name="Patterns, Relationships, and Algebraic Reasoning" Expectation="The student will demonstrate an understanding of patterns, relationships, and algebraic reasoning.">
      </Category>
    </Categories>
  </Level>
</Levels>

我這樣做是因為我需要在WPF中的TreeView控件中訪問此信息。 但是同時，我的SQL數據庫中有一個表，該表需要存儲用戶正在使用的Level目標： 7.1A, 7.1B, 7.1C, 7.2A 。

這是一個好習慣嗎？ 還是我沒有保留兩個數據之間的關系。

@DarfZon，我將數據保留為一種格式（如果您的其他數據也是關系型的，我的建議是使用SQL Server）。 您可以使用SQL Server強大的XML語法和FOR XML子句以分層格式檢索SQL Server中的關系數據。
