　　1. JSON Model



{
company: {
name: "Treefish Inc",
info: {
employees: 3,
},
contacts: [
{
name: "Barbara",
phone: "873"
},
{
name: "Gerry",
phone: "734"
},
{
name: "Susan",
phone: "275"
}
]
}
}
　　访问路径：

/company/name
/company/info/employees
/company/contacts
　　2. OData Model
　　sap.ui.model.odata.ODataModel 不建议使用，使用sap.ui.model.odata.v2.ODataModel替代。
　　声明OData Model



1 var oModel = new sap.ui.model.odata.v2.ODataModel("http://services.odata.org/Northwind/Northwind.svc/");
2 var oModel = new sap.ui.model.odata.v2.ODataModel({serviceUrl: "http://services.odata.org/Northwind/Northwind.svc"});
　　获取OData Service metadata:



var oMetadata = oModel.getServiceMetadata();
　　请求OData Service数据时可以添加额外的信息：



1 var oModel = new sap.ui.model.odata.v2.ODataModel({
2     serviceUrl: "http://services.odata.org/Northwind/Northwind.svc",   
3     serviceUrlParams: {
4         myParam: "value1",
5         myParam2: "value2"
6     },
7     metadataUrlParams: {
8         myParam: "value1",
9         myParam2: "value2"
10     }
11 });
　　请求Service数据时 会访问

"http://myserver/MyService.svc/?myParam=value&myParam2=value2"这个路径，
同理请求metadata时也是一样：(TODO)
　　获取数据：



1 oModel.getData("/Customer('ALFKI')");
2 oModel.getProperty("/Customer('ALFKI')/Address");


var oData = {
ProductId: 999,
ProductName: "myProduct"
}
//POST
oModel.create("/Products", oData, {success: mySuccessHandler, error: myErrorHandler});
//GET
oModel.read("/Products(999)", {success: mySuccessHandler, error: myErrorHandler});
//PUT
var oData = {
ProductId: 999,
ProductName: "myProductUpdated"
}
oModel.update("/Products(999)", oData, {success: mySuccessHandler, error: myErrorHandler});
//DELETE
oModel.delete("/Products(999)", {success: mySuccessHandler, error: myErrorHandler});
　　更改完成后OModel会自动refresh
　　oModel.setRefreshAfterChange(false); //关闭自动刷新
　　TODO
　　





　　
　　3. XML Model
