# SCHEMA

This file represents the initial schema for the various data structures to be stored in the database.

These schema definitions target SQLite v3.

# Persons Table
The Persons table will contain data about Person entities (see MODELS.md)

``` sql
CREATE TABLE Persons (
	id TEXT(36),    /* UUIDv4 */
	remote_id TEXT, /* field to store an arbitrary remote identifier for this Person if they are not local */
	name TEXT,      /* "real" name */
	handle TEXT,    /* also commonly refered to as 'display_name' or 'screen_name', optional (if missing, name will be used as handle) */
	is_active INTEGER DEFAULT (1),    /* bool, default true */
	is_blocked INTEGER DEFAULT (0),   /* bool, default false */
	created_at INTEGER,               /* timestamp */
	modified_at INTEGER,              /* timestamp */
	modified_by TEXT(36),             /* UUIDv4 */
	deleted_at INTEGER,               /* timestamp */
	deleted_by TEXT(36),              /* UUIDv4 */
	last_seen INTEGER,                /* timestamp */
	shipping_address TEXT,            /* optional, should use \n between lines to keep localized format as needed */
	CONSTRAINT Persons_PK PRIMARY KEY (id),
	CONSTRAINT Persons_FK FOREIGN KEY (modified_by) REFERENCES Persons(id),
	CONSTRAINT Persons_FK_1 FOREIGN KEY (deleted_by) REFERENCES Persons(id)
);
CREATE UNIQUE INDEX Persons_remote_id_IDX ON Persons (remote_id);
CREATE INDEX Persons_name_IDX ON Persons (name);
CREATE INDEX Persons_handle_IDX ON Persons (handle);
CREATE INDEX Persons_is_active_IDX ON Persons (is_active);
CREATE INDEX Persons_is_blocked_IDX ON Persons (is_blocked);
CREATE INDEX Persons_deleted_at_IDX ON Persons (deleted_at);
```

# PersonEmails Table
The PersonEmails table is a one-to-many lookup table relating a Person to zero or more email addresses

``` sql
CREATE TABLE PersonEmails (
	person_id TEXT(36),
	email TEXT,
	is_verified INTEGER DEFAULT (0),
	is_primary INTEGER DEFAULT (0),
	CONSTRAINT PersonEmails_PK PRIMARY KEY (email),
	CONSTRAINT PersonEmails_FK FOREIGN KEY (person_id) REFERENCES Persons(id) ON DELETE CASCADE
);
CREATE INDEX PersonEmails_person_id_IDX ON PersonEmails (person_id);
CREATE INDEX PersonEmails_is_verified_IDX ON PersonEmails (is_verified);
CREATE INDEX PersonEmails_is_primary_IDX ON PersonEmails (is_primary);
```
