<!-- OAT(OSS Audit Tool) configuration guide:
basedir: Root dir, the basedir + project path is the real source file location.
licensefile:
1.If the project don't have "LICENSE" in root dir, please define all the license files in this project in , OAT will check license files according to this rule.
tasklist(only for batch mode):
1. task: Define oat check thread, each task will start a new thread.
2. task name: Only an name, no practical effect.
3. task policy: Default policy for projects under this task, this field is required and the specified policy must defined in policylist.
4. task filter: Default filefilter for projects under this task, this field is required and the specified filefilter must defined in filefilterlist.
5. task project: Projects to be checked, the path field define the source root dir of the project.
policyList:
1. policy: All policyitems will be merged to default OAT.xml rules, the name of policy doesn't affect OAT check process.
2. policyitem: The fields type, name, path, desc is required, and the fields rule, group, filefilter is optional,the default value is:
<policyitem type="" name="" path="" desc="" rule="may" group="defaultGroup" filefilter="defaultPolicyFilter"/>
3. policyitem type:
"compatibility" is used to check license compatibility in the specified path;
"license" is used to check source license header in the specified path;
"copyright" is used to check source copyright header in the specified path;
"import" is used to check source dependency in the specified path, such as import ... ,include ...
"filetype" is used to check file type in the specified path, supported file types: archive, binary
"filename" is used to check whether the specified file exists in the specified path(support projectroot in default OAT.xml), supported file names: LICENSE, README, README.OpenSource
4. policyitem name: This field is used for define the license, copyright, "*" means match all, the "!" prefix means could not match this value. For example, "!GPL" means can not use GPL license.
5. policyitem path: This field is used for define the source file scope to apply this policyitem, the "!" prefix means exclude the files. For example, "!.*/lib/.*" means files in lib dir will be exclude while process this policyitem.

## Introduction<a name="section11660541593"></a>
The **relational database \(RDB\)** manages data based on relational models. With the underlying SQLite database, the OpenHarmony RDB provides a complete mechanism for managing local databases.
The **preferences database** provides lightweight key-value operations for local applications to store a small amount of data. As the stored data is already loaded in the memory, the faster data access speed achieves a higher work efficiency. The preferences database is non-relational, and therefore it is not suitable for storing a large amount of data. Instead, the preferences database is usually used to operate data in key-value pairs.
### RDB<a name="section1589234172717"></a>
With the SQLite database as the persistence engine, the OpenHarmony RDB supports all features of the SQLite database , including but not limited to transactions, indices, views, triggers, foreign keys, parameterized queries, and prepared SQL statements.
**Figure 1** How RDB works<a name="fig3330103712254"></a>
![](figures/en-us_How_RDB_works.png)
### Preferences Database<a name="section1287582752719"></a>
1. The preferences database provides operation classes for applications to operate the database.
2. With the **PreferencesHelper**, an app can load the content of a specified file to the **Preferences** instance. Each file has only one **Preferences** instance. The system stores the instance in the memory through a static container until the app removes the instance from the memory or deletes the file.
3. After obtaining the **Preferences** instance, the app can use the functions in **Preferences** to read data from or write data to the **Preferences** instance, and use **flush\(\)** or **flushSync\(\)** to save the modification to the file that stores the preference data.

## Relational Database<a name="section101010894114"></a>
Some basic concepts are as follows:
- **Relational database \(RDB\)**
A database created on the basis of relational models. The RDB stores data in rows and columns.
- **Result set**
A set of query results used to access the data. You can access the required data in a result set in flexible modes.
- **SQLite database**
A lightweight RDB in compliance with the atomicity, consistency, isolation, and durability \(ACID\) properties. It is an open-source database.
### Constraints<a name="section18387142613414"></a>
The RDB can use a maximum of four connection pools to manage read and write operations.
To ensure data accuracy, the RDB supports only one writ operation at a time.
## Preferences Database<a name="section762641474720"></a>
Some basic concepts are as follows:
- **Key-value database**
A database that stores data in key-value pairs. The **key** indicates keyword, and **value** indicates the corresponding value.
- **Non-relational database**
A database not in compliance with the atomicity, consistency, isolation, and durability \(ACID\) database management properties of relational data transactions. Instead, the data in a non-relational database is independent and scalable.
- **Preference** **data**
A type of data that is frequently accessed and used.
### Constraints<a name="section1944481420489"></a>
A key should be a string with a maximum of 80 characters and cannot be an empty string.
A value in the format of string can have a maximum of 8192 characters. A value can be an empty string.
To avoid a high memory cost, it is recommended that the preferences database store no more than ten thousand data entries.

# 本地数据管理组件
# 关系型数据库（Relational Database，RDB）
## 简介
### [关系型数据库（Relational Database，RDB）](relational_store/README_zh.md)
是一种基于关系模型来管理数据的数据库。OpenHarmony关系型数据库基于SQLite组件提供了一套完整的对本地数据库进行管理的机制。
### [首选项（Preferences）](preferences/README_zh.md)
**关系型数据库（Relational Database，RDB）** 是一种基于关系模型来管理数据的数据库。OpenHarmony关系型数据库基于SQLite组件提供了一套完整的对本地数据库进行管理的机制。
OpenHarmony关系型数据库底层使用SQLite作为持久化存储引擎，支持SQLite具有的所有数据库特性，包括但不限于事务、索引、视图、触发器、外键、参数化查询和预编译SQL语句。
主要提供轻量级Key-Value操作，支持本地应用存储少量数据，数据存储在本地文件中，同时也加载在内存中，所以访问速度更快，效率更高。首选项提供非关系型数据存储，不宜存储大量数据，经常用于操作键值对形式数据的场景。
### [数据共享（DataShare）](data_share/README_zh.md)
以下是几个基本概念：
- **关系型数据库**
主要用于应用管理其自身数据，同时支持同个设备上不同应用间的数据共享。
### [轻量系统KV数据库（Lightweight KV store）](kv_store/README_zh.md)
创建在关系模型基础上的数据库，以行和列的形式存储数据。
- **结果集**
指用户查询之后的结果集合，可以对数据进行访问。结果集提供了灵活的数据访问方式，可以更方便的拿到用户想要的数据。
- **SQLite数据库**
一款轻量级的数据库，是遵守ACID的关系型数据库组件。它是一个开源的项目。
**图 1** 关系型数据库运作机制
![](figures/zh-cn_关系型数据库运作机制.png)
依托当前公共基础库提供的KV存储能力开发，为轻量系统设备应用提供键值对数据管理能力。在有进程的平台上，KV存储提供的参数管理，供单进程访问不能被其他进程使用。在此类平台上，KV存储作为基础库加载在应用进程，以保障不被其他进程访问。

## 约束
数据库中连接池的最大数量是4个，用以管理用户的读写操作。
为保证数据的准确性，数据库同一时间只能支持一个写操作。

# 数据共享
## 简介
**数据共享（Data Share）** 提供了向其他应用共享以及管理其数据的方法，支持同个设备上不同应用之间的数据共享。
**图 1** 逻辑架构图
![](figures/zh-cn_dataShare.png)
- DataShareExtAbility模块为数据提供方，实现跨应用数据共享的相关业务。
- DataShareHelper模块为数据访问方，提供各种访问数据的接口，包括增删改查等。
- 数据访问方与提供方通过IPC进行通信，数据提供方可以通过数据库实现，也可以通过其他数据存储方式实现。
- ResultSet模块通过共享内存实现，用于存储查询数据得到的结果集，并提供了遍历结果集的方法。

```
## 约束
- DataShare受到数据提供方所使用数据库的一些限制。例如支持的数据模型、Key的长度、Value的长度、每个应用程序支持同时打开数据库的最大数量等，都会受到使用的数据库的限制。
- 因DataShare内部实现依赖于IPC通信，所以数据集、谓词、结果集等的载荷受到IPC通信的约束与限制。
