BI数据分析是目前企业的热门应用，而对企业来说，权限控制是非常重要的，尤其是作为决策用的企业报表。目前基于微软SQL Server体系的BI架构为Integration Services + Analysis Service + Reporting Services，Integration Services和Analysis都属于应用后台的服务，不会在用户前端展现，其权限控制体系不在我们这篇文章的讨论范围内（但是实现数据级权限控制，需要Analysis Services的参与）。而对于前端展示用的企业报表，权限控制体系分为2种：报表级权限和数据级权限。报表级权限较为简单，主要用于控制谁能够看这个报表；数据级权限则比较复杂了，任何人看同一张报表，报表上的数据只能是他有权限查看的数据。简单说，就是总经理看到的数据和经理看到的数据是不一样的，虽然他们在看同一张报表。比较报表级权限和数据级权限，会发现如果实现了数据级权限的控制，那么企业报表是否需要进行权限控制已经不再重要（当然，为了界面友好性，还是应该控制下的）。
这篇文章主要就是讲述基于SQL Server架构的BI数据级权限的解决方案，这也是我给一个德国大型跨国企业客户实施其BI项目中，对方非常重视的一个功能。这里先简单介绍下这个客户和项目，出于保密要求，我把该客户叫做Customer S（简称CS，呵呵，不是那个游戏哦）。
CS项目前端采用Sharepoint，后台采用SQL Server，主要分析客户S的销售数据。CS的组织结构分为部门、区域；部门和区域是相互交叉的；某个部门的总部人员能够看到全国所有区域的数据；而区域员工则只能看到该区域的数据了。用户能够查看的数据权限，需要在网页上可以进行配置。这就是客户对数据级权限的要求。
针对这些需求，数据级权限解决方案采用如下架构：

Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AMInnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
