-Flink programs are regular programs that implement transformations on
distributed collections
-(e.g., filtering, mapping, updating state, joining, grouping, defining
windows, aggregating).
-Collections are initially created from sources (e.g., by reading from files,
kafka topics, or from local, in-memory
-collections). Results are returned via sinks, which may for example write the
data to
-(distributed) files, or to standard output (for example, the command line
terminal).
-Flink programs run in a variety of contexts, standalone, or embedded in other
programs.
-The execution can happen in a local JVM, or on clusters of many machines.
-
-Depending on the type of data sources, i.e. bounded or unbounded sources, you
would either
-write a batch program or a streaming program where the DataSet API is used for
batch
-and the DataStream API is used for streaming. This guide will introduce the
basic concepts
-that are common to both APIs but please see our
-[Streaming Guide]({{ site.baseurl }}/dev/datastream_api.html) and
-[Batch Guide]({{ site.baseurl }}/dev/batch/index.html) for concrete
information about
-writing programs with each API.
-
-**NOTE:** When showing actual examples of how the APIs can be used we will use
-`StreamingExecutionEnvironment` and the `DataStream` API. The concepts are
exactly the same
-in the `DataSet` API, just replace by `ExecutionEnvironment` and `DataSet`.

程序是实现了分布式集合转换（例如过滤、映射、更新状态、join、分组、定义窗口、聚合）的规范化程序。集合初始创建自数据源（例如读取文件、kafka
主题，或本地内存中的集合）。结果通过 sink 返回，例如，它可以将数据写入（分布式）文件，或标准输出（例如命令行终端）。Flink
程序可以在多种环境中运行，独立运行或嵌入到其他程序中。可以在本地 JVM 中执行，也可以在多台机器的集群上执行。
+
+针对有界和无界两种数据源类型，你可以使用 DataSet API 来编写批处理程序或使用 DataStream API
来编写流处理程序。本篇指南将介绍这两种 API 通用的基本概念，使用每种 API 编写程序的具体信息请查阅
Review comment:
`使用每种 API 编写程序的具体信息请查阅` 去掉 `每种` 或者说重新写作 `具体使用 API 编写程序的方法请查阅` 或通顺一点。
