For example, system designers could create an internal interface package to utilize third-party billing code but only expose interfaces to those packages that use the billing code.

例如，系统设计师可以创建一个内部接口包来利用第三方记帐代码，但是只对这些使用记帐代码的包公开接口。

Not only does the dao package now directly utilize a third-party billing package, but another package that wasn't even intended to use any billing code directly references both billing packages!

现在不仅 dao 包直接利用第三方记帐包，而且另一个甚至不想直接使用任何记帐代码的包也引用了这两个记帐包！

Advanced platforms that have a limited instance-level ability to provide metering and billing often opt to provide generalized billing models in which there is a flat fee to run application code.

在计费和计量方面存在实例层功能局限的高级平台，会选择提供通用计费模式，这种模式在运行应用程序代码时会产生固定费用。

Before making changes to the internal billing package, you could analyze a code coverage report to determine if any tests actually tested the package.

在对内部记帐包作出变更前，您可以分析代码覆盖率报告，以确定是否有任何测试真正测试了这个包。

The country fields for billing and shipping contain a two-letter country code such as DE for Germany or US for the United States.

用于支付和运送的country字段包含一个两个字母的国家代码，例如DE表示德国，或者US表示美国。

The state fields for billing and shipping contain a two-letter state code such as 01 in Germany or CA in the United States.

用于支付和运送的 state 字段包含一个两个字母的州代码，例如德国中的 01 或者美国中的 CA。

Actual usage billing enables PaaS providers to run application code from multiple tenants across the same set of hardware depending on the granularity of usage monitoring.

实际使用收费让PaaS供应商能根据使用监视的粒度在同组硬件上的多租户中运行程序代码。

User billing is based on the purchase of the decryption access codes as indicated by the access code attributes encoded on the media.

用户计费是基于由介质上编码的存取码属性指示的解密存取码的购买。

The realization of a C# coffee shop order/billing system source code, C/S mode, can also be used for small restaurants to use.

说明：一个C#实现咖啡厅点单/结账系统源码，C/S的，也可用于小型餐饮店使用。
