DBD = Database Designer，是Vertica数据库优化中最主要的原生工具。
首先运行admintools工具,按下面步骤依次执行：
1.选择"6 Configuration Menu"
2.选择"2 Run Database Designer"
3."Select a database for design" 选择需要分析的数据库
4."Enter directory for Database Designer output:" 输入dbd的输出目录
5."Designer name:" 输入dbd的名字，随意起
6."Design Type[Comprehensive|Query-specific]" 选择dbd的设计类型，有两个单选项，根据实际需求选择
7."Select schema(s) for design" 选择需要设计的shema(s)
8."Design options[Optimize with queries|Update statistics|Deploy design]" 这里有三个复选项，推荐先去掉Deploy design，之后可以手工应用dbd的建议
9."Enter the full path for queries file" 输入业务常用到的sql查询语句，使得dbd的分析更有针对性
10."Proposed K-safety value:1" 这里默认即可
11."Select storage footprint preference[Balanced query/load performance|Query performance(larger footprint)|Load performance(smaller footprint)]" 这里有三个单选项，根据实际需求选择，一般选择第一项，均衡兼顾查询和加载性能
12."Proceed" 执行dbd
13."Database Designer started." dbd已经开始，会有类似下面的输出，直到完成dbd
