# 须知

我们的App例子是一个简单的图书借阅程序，它包含了两个重要的Module: Book（图书） and Member（会员）

  1. 会员的主页会显示该会员的借阅历史记录
  2. 图书的Available属性用于标识它是否可以被借阅
  3. 每本图书都有一个ISBN码,每次保存的时候都会检查该码的有效性
  4. 用户可以手动检查ISBN码是否有效
  5. 为会员添加了一个打印报告的功能
  6. 为会员添加了一个EBI（Multiable的商业智能报告）的功能

你可以在 github (opens new window) 下载到整个App的可运行代码，然后参照设置Eclipse开发环境去运行这个程序。

# 在App.xml中定义App的各项属性

p-share\src\main\resources\META-INF\app.xml

<?xml version="1.0"?>
<app xmlns="http://www.multiable.com/app">
	<name>opcq</name>
	<version>1.0</version>
	<description>Opcq App</description>
	<dependences>
		<dependence id="caw" versions="1.0" />
	</dependences>	
	<ear>caw_ear</ear>
	<ejb>p-ejb</ejb>	
</app>

更多可设置的参数请参见 App.xml .

# 在datadict.xml中定义表结构

p-share\src\main\resources\META-INF\datadict.xml

<?xml version="1.0"?>

</dd>

更多可设置的参数请参见 Datadict.xml.

出于重用和统一修改的目的，栏位的属性可以在 Pattern.xml 中统一进行定义.

<?xml version="1.0"?>
<pattern xmlns="http://www.multiable.com/pattern">

	<record code="opcqBookCat" type="lookup">
		<lookup searchType="opcqBookCat"/>
	</record>
	
	<record code="opcqBook" type="lookup">
		<lookup searchType="opcqBook"/>
	</record>			
	
	<record code="opcqMem" type="lookup">
		<lookup searchType="opcqMem"/>
	</record>
</pattern>

# 在module.xml中定义Module

这个App总共有三个Module，它们分别是:

  1. Book Category
  2. Book
  3. Member

p-share\src\main\resources\META-INF\module.xml

<?xml version="1.0"?>
<md xmlns="http://www.multiable.com/module" app="opcq">

	<module name="opcqBookCat" mess="opcq.bookCat" extend="false" mainTable="opcqbookcat" recType="" useAccess="true" useAttach="true" useBeShare="true" useApv="true" useChangenote="true" fmShare="Y" genCode_Type="BC">
