+# Contributor Covenant Code of Conduct
+
+The following code of conduct is based on full compliance with [ASF CODE OF CONDUCT](https://www.apache.org/foundation/policies/conduct.html).
+
+## Development Concept
+
+ - Write codes with heart. Pursue clean, simplified and extremely elegant codes. Agree with concepts in <Refactoring: Improving the Design of Existing Code> and <Clean Code: A Handbook of Agile Software Craftsmanship>.
+ - Be familiar with codes already had, to keep consistent with the style and use.
+ - Highly reusable, no duplicated codes or configurations.
+ - Delete codes out of use in time.
+
+## Contributor Covenant Submitting of Conduct
+
+ - Make sure all the test cases are passed, Make sure `mvn clean install` can be compiled and tested successfully.
+ - Make sure the test coverage rate is not lower than the dev branch.
+ - Make sure to check codes with Checkstyle. codes that violate check rules should have special reasons. Find checkstyle template from `sharding-sphere/src/resources/sharding_checks.xml`, please use checkstyle `8.8` to run the rules.
+
+## Contributor Covenant Code of Conduct
+
+ - Use linux line separators.
+ - Keep indents (including blank lines) consistent with the previous one.
+ - Keep one blank line after class definition.
+ - No meaningless blank lines.
+ - Use meaningful class, method and variable names, avoid to use abbreviate. 
+ - Return values are named with `result`; Variables in the loop structure are named with `each`; Replace `each` with `entry` in map.
+ - Exceptions when catch are named with `ex`; Exceptions when catch but do nothing are named with `ignored`.
+ - Name property files with camel-case and lowercase first letters.
+ - Have constants on the left and variable on the right in `==` and `equals` conditional expressions; Have variable on the left and constants on the right in `greater than` and `less than` conditional expressions.
+ - Use `LinkedList`  in priority. Use `ArrayList` for use index to get element only.
+ - Use capacity based `Collection` such as `ArrayList`, `HashMap` must indicate initial capacity to avoid recalculate capacity.
+ - Design class as `final` class expect abstract class for extend.
+ - Make nested loop structures a new method.
+ - Use guard clauses in priority.
+ - Minimize the access permission for classes and methods.
+ - Private method should be just next to the method in which it is used; writing private methods should be in the same as the appearance order of private methods.
+ - No `null` parameters or return values.
+ - Split codes that need to add notes with it into small methods, which are explained with method names.
+ - Replace constructors, getters, setter methods and log variable with lombok in priority.
+ - Use English in all the logs and javadoc.
+ - Include Javadoc, todo and fixme only in the comments.
+ - Only `public` classes and methods need javadoc, other methods, classes and override methods do not need javadoc.
+
+## Contributor Covenant Unit Test of Conduct
+
+ - Test codes and production codes should follow the same kind of code of conduct.
+ - Without particular reasons, test cases should be fully covered.
+ - Environment preparation codes should be separate from test codes.
+ - Only those that relate to junit `Assert`, hamcrest `CoreMatchers` and `Mockito` can use static import.
+ - For single parameter asserts, `assertTrue`, `assertFalse`, `assertNull` and `assertNotNull` should be used.
+ - For multiple parameter asserts, `assertThat` should be used.
+ - For accurate asserts, try not to use `not`, `containsString` to make assertions.
+ - Actual values of test cases should be named `actualXXX`, expected values `expectedXXX`.
+ - Class for test case and `@Test` annotation do not need javadoc.

+Apache ShardingSphere (incubating) is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator PMC.
+Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, 
+communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. 
+While incubation status is not necessarily a reflection of the completeness or stability of the code, 
+it does indicate that the project has yet to be fully endorsed by the ASF.

+
+## Overview
+
+This is an assessment of the ShardingSphere podling’s maturity, meant to help inform the decision (of the mentors, community, Incubator PMC and ASF Board of Directors) to graduate it as a top-level Apache project.
+
+It is based on the ASF project maturity model at https://community.apache.org/apache-way/apache-project-maturity-model.html
+
+## Status of this document
+
+All open items are updated with the latest status.

+
+## Overview
+
+ShardingSphere is an open-source ecosystem consisted of a set of distributed database middleware solutions, including 2 independent products, Sharding-JDBC & Sharding-Proxy & Sharding-Sidecar (todo). 
+They all provide functions of data sharding, distributed transaction and database orchestration, applicable in a variety of situations such as Java isomorphism, heterogeneous language and cloud native. 
+
+Aiming at reasonably making full use of the computation and storage capacity of the database in a distributed system, ShardingSphere defines itself as a middleware, rather than a totally new type of database. 
+As the cornerstone of many enterprises, relational database still takes a huge market share. 
+Therefore, at the current stage, we prefer to focus on its increment instead of a total overturn.
+
+__Apache releases are beginning from version 4.0.0__
+
+![ShardingSphere Scope](https://shardingsphere.apache.org//document/current/img/shardingsphere-scope_en.png)
+
+### Sharding-JDBC
+
+[![Maven Status](https://maven-badges.herokuapp.com/maven-central/org.apache.shardingsphere/sharding-jdbc/badge.svg)](https://mvnrepository.com/artifact/org.apache.shardingsphere/sharding-jdbc)
+
+Sharding-JDBC defines itself as a lightweight Java framework that provides extra service at Java JDBC layer. 
+With the client end connecting directly to the database, it provides service in the form of jar and requires no extra deployment and dependence. 
+It can be considered as an enhanced JDBC driver, which is fully compatible with JDBC and all kinds of ORM frameworks.
+
+* Applicable in any ORM framework based on JDBC, such as JPA, Hibernate, Mybatis, Spring JDBC Template or direct use of JDBC.
+* Support any third-party database connection pool, such as DBCP, C3P0, BoneCP, Druid, HikariCP.
+* Support any kind of JDBC standard database: MySQL, Oracle, SQLServer, PostgreSQL and any SQL92 followed databases.
+
+![Sharding-JDBC Architecture](https://shardingsphere.apache.org//document/current/img/sharding-jdbc-brief.png)
+
+### Sharding-Proxy
+
+[![Download](https://img.shields.io/badge/release-download-orange.svg)](https://www.apache.org/dyn/closer.cgi?path=incubator/shardingsphere/4.0.0-RC3/apache-shardingsphere-incubating-4.0.0-RC3-sharding-proxy-bin.tar.gz)
+[![Docker Pulls](https://img.shields.io/docker/pulls/shardingsphere/sharding-proxy.svg)](https://store.docker.com/community/images/shardingsphere/sharding-proxy)
+
+Sharding-Proxy defines itself as a transparent database proxy, providing a database server that encapsulates database binary protocol to support heterogeneous languages. 
+Friendlier to DBA, the MySQL/PostgreSQL version provided now can use any kind of client access (such as MySQL Command Client, MySQL Workbench, Navicat etc.) that is compatible of MySQL/PostgreSQL protocol to operate data.
+
+* Totally transparent to applications, it can be used directly as MySQL and PostgreSQL.
+* Applicable to any kind of compatible client end that is compatible with MySQL and PostgreSQL protocol.
+
+![Sharding-Proxy Architecture](https://shardingsphere.apache.org//document/current/img/sharding-proxy-brief_v2.png)
+
+### Sharding-Sidecar(TODO)
+
+Sharding-Sidecar (TODO) defines itself as a cloud native database agent of the Kubernetes environment, in charge of all the access to the database in the form of sidecar. 
+It provides a mesh layer interacting with the database, we call this as `Database Mesh`.
+
+Database Mesh emphasizes on how to connect distributed database access application with the database. 
+Focusing on interaction, it effectively organizes the interaction between messy applications and the database. 
+The application and database that use Database Mesh to visit database will form a large grid system, where they just need to be put into the right position accordingly. 
+They are all governed by the mesh layer.
+
+![Sharding-Sidecar Architecture](https://shardingsphere.apache.org//document/current/img/sharding-sidecar-brief_v2.png)
+

+
+### Hybrid Architecture
+
+Sharding-JDBC adopts decentralized architecture, applicable to high-performance light-weight OLTP application developed with Java; 
+Sharding-Proxy provides static entry and all languages support, applicable for OLAP application and the sharding databases management and operation situation.
+
+ShardingSphere is an ecosphere consists of multiple endpoints together.
+Through a mixed use of Sharding-JDBC and Sharding-Proxy and unified sharding strategy by the same registry center, ShardingSphere can build an application system applicable to all kinds of scenarios. 
+Architects can adjust the system architecture to the most applicable one to current business more freely.

+
+## 概述
+
+ShardingSphere是一套开源的分布式数据库中间件解决方案组成的生态圈，它由Sharding-JDBC、Sharding-Proxy和Sharding-Sidecar（计划中）这3款相互独立的产品组成。
+他们均提供标准化的数据分片、分布式事务和数据库治理功能，可适用于如Java同构、异构语言、云原生等各种多样化的应用场景。
+
+ShardingSphere定位为关系型数据库中间件，旨在充分合理地在分布式的场景下利用关系型数据库的计算和存储能力，而并非实现一个全新的关系型数据库。
+它与NoSQL和NewSQL是并存而非互斥的关系。NoSQL和NewSQL作为新技术探索的前沿，放眼未来，拥抱变化，是非常值得推荐的。反之，也可以用另一种思路看待问题，放眼未来，关注不变的东西，进而抓住事物本质。
+关系型数据库当今依然占有巨大市场，是各个公司核心业务的基石，未来也难于撼动，我们目前阶段更加关注在原有基础上的增量，而非颠覆。
+
+ShardingSphere目前已经进入[Apache孵化器](http://incubator.apache.org/projects/shardingsphere.html)，
+欢迎通过[shardingsphere的dev邮件列表](mailto:dev@shardingsphere.apache.org)与我们讨论。
+
+__Apache官方发布从4.0.0版本开始。__

+
+### Sharding-JDBC
+
+[![Maven Status](https://maven-badges.herokuapp.com/maven-central/org.apache.shardingsphere/sharding-jdbc/badge.svg)](https://mvnrepository.com/artifact/org.apache.shardingsphere/sharding-jdbc)
+
+定位为轻量级Java框架，在Java的JDBC层提供的额外服务。
+它使用客户端直连数据库，以jar包形式提供服务，无需额外部署和依赖，可理解为增强版的JDBC驱动，完全兼容JDBC和各种ORM框架。
+
+* 适用于任何基于JDBC的ORM框架，如：JPA, Hibernate, Mybatis, Spring JDBC Template或直接使用JDBC。
+* 支持任何第三方的数据库连接池，如：DBCP, C3P0, BoneCP, Druid, HikariCP等。
+* 支持任意实现JDBC规范的数据库。目前支持MySQL，Oracle，SQLServer，PostgreSQL以及任何遵循SQL92标准的数据库。
+
+![Sharding-JDBC Architecture](https://shardingsphere.apache.org//document/current/img/sharding-jdbc-brief.png)
+
+### Sharding-Proxy
+
+[![Download](https://img.shields.io/badge/release-download-orange.svg)](https://www.apache.org/dyn/closer.cgi?path=incubator/shardingsphere/4.0.0-RC3/apache-shardingsphere-incubating-4.0.0-RC3-sharding-proxy-bin.tar.gz)
+[![Docker Pulls](https://img.shields.io/docker/pulls/shardingsphere/sharding-proxy.svg)](https://store.docker.com/community/images/shardingsphere/sharding-proxy)
+
+定位为透明化的数据库代理端，提供封装了数据库二进制协议的服务端版本，用于完成对异构语言的支持。
+目前先提供MySQL和PostgreSQL版本，它可以使用任何兼容MySQL和PostgreSQL协议的访问客户端(如：MySQL Command Client, MySQL Workbench, Navicat等)操作数据，对DBA更加友好。
+
+* 向应用程序完全透明，可直接当做MySQL或PostgreSQL使用。
+* 适用于任何兼容MySQL或PostgreSQL协议的的客户端。
+
+![Sharding-Proxy Architecture](https://shardingsphere.apache.org//document/current/img/sharding-proxy-brief_v2.png)
+
+### Sharding-Sidecar（TODO）
+
+定位为Kubernetes的云原生数据库代理，以Sidecar的形式代理所有对数据库的访问。
+通过无中心、零侵入的方案提供与数据库交互的的啮合层，即Database Mesh，又可称数据库网格。
+
+Database Mesh的关注重点在于如何将分布式的数据访问应用与数据库有机串联起来，它更加关注的是交互，是将杂乱无章的应用与数据库之间的交互有效的梳理。
+使用Database Mesh，访问数据库的应用和数据库终将形成一个巨大的网格体系，应用和数据库只需在网格体系中对号入座即可，它们都是被啮合层所治理的对象。
+
+![Sharding-Sidecar Architecture](https://shardingsphere.apache.org//document/current/img/sharding-sidecar-brief_v2.png)
+
+|           | *Sharding-JDBC* | *Sharding-Proxy* | *Sharding-Sidecar* |
+| --------- | --------------- | ---------------- | ------------------ |
+| 数据库     | 任意            | MySQL/PostgreSQL | MySQL/PostgreSQL   |
+| 连接消耗数 | 高              | 低               | 高                  |
+| 异构语言   | 仅Java          | 任意             | 任意                |
+| 性能       | 损耗低          | 损耗略高          | 损耗低              |
+| 无中心化   | 是              | 否               | 是                  |
+| 静态入口   | 无              | 有               | 无                  |
+
+### 混合架构
+
+Sharding-JDBC采用无中心化架构，适用于Java开发的高性能的轻量级OLTP应用；Sharding-Proxy提供静态入口以及异构语言的支持，适用于OLAP应用以及对分片数据库进行管理和运维的场景。
+
+ShardingSphere是多接入端共同组成的生态圈。
+通过混合使用Sharding-JDBC和Sharding-Proxy，并采用同一注册中心统一配置分片策略，能够灵活的搭建适用于各种场景的应用系统，使得架构师更加自由的调整适合与当前业务的最佳系统架构。
