The database scripts include scripts for defining code lists and external systems, for creating tables and indexes, and for dropping tables and indexes. These scripts appear under the Database Script node of the master index project, and are named Systems, Code List, Create User Indexes, Drop User Indexes, Create User Code Data, Create Person Database, and Drop Person Database. You can modify these scripts as needed to customize the tables, indexes, startup data, and database distribution. You can also create new database scripts if needed.
