Postgres Schemas

​
1. calendars

Stores calendar entries for each employee, including availability and meetings.

CREATE TABLE calendars (
    tenant_id UUID,
    calendar_id UUID DEFAULT gen_random_uuid(),
    user_id UUID,
    event_date TIMESTAMP NOT NULL,
    event_type VARCHAR(50) NOT NULL, -- e.g., "meeting", "available", "unavailable"
    event_details JSONB,
    PRIMARY KEY (tenant_id, calendar_id),
    FOREIGN KEY (tenant_id, user_id) REFERENCES users.tenant_users(tenant_id, user_id)
);

​
2. meetings

Stores meeting information, including participants, time, location, and status. The embeddings are stored for the details of each meetings. This helps the AI model to understand meeting distribution and how time is spent.

CREATE TABLE meetings (
    tenant_id UUID,
    meeting_id UUID DEFAULT gen_random_uuid(),
    organizer_id UUID,
    meeting_time TIMESTAMP NOT NULL,
    location VARCHAR(255),
    status VARCHAR(50), -- e.g., "scheduled", "completed", "canceled"
    details TEXT,
    vector_embedding VECTOR(768), -- Adjust the dimensions as needed
    PRIMARY KEY (tenant_id, meeting_id),
    FOREIGN KEY (tenant_id, organizer_id) REFERENCES users.tenant_users(tenant_id, user_id)
);

​
3. meeting_participants

Maps participants to meetings, tracking which employees are involved in each meeting.

CREATE TABLE meeting_participants (
    tenant_id UUID,
    meeting_id UUID,
    user_id UUID,
    PRIMARY KEY (tenant_id, meeting_id, user_id),
    FOREIGN KEY (tenant_id, meeting_id) REFERENCES meetings(tenant_id, meeting_id),
    FOREIGN KEY (tenant_id, user_id) REFERENCES users.tenant_users(tenant_id, user_id)
);

​
4. reminders

Stores reminders for meetings, including the reminder time and message.

CREATE TABLE reminders (
    tenant_id UUID,
    reminder_id UUID DEFAULT gen_random_uuid(),
    meeting_id UUID,
    reminder_time TIMESTAMP NOT NULL,
    message TEXT,
    PRIMARY KEY (tenant_id, reminder_id),
    FOREIGN KEY (tenant_id, meeting_id) REFERENCES meetings(tenant_id, meeting_id)
);

​
5. meeting_statistics

Stores statistics on meeting attendance and duration for analysis and optimization.

CREATE TABLE meeting_statistics (
    tenant_id UUID,
    stat_id UUID DEFAULT gen_random_uuid(),
    meeting_id UUID,
    duration_minutes INT,
    attended BOOLEAN,
    PRIMARY KEY (tenant_id, stat_id),
    FOREIGN KEY (tenant_id, meeting_id) REFERENCES meetings(tenant_id, meeting_id)
);

​
6. shared_calendars

Stores information about calendars shared between users for collaborative scheduling.

CREATE TABLE shared_calendars (
    tenant_id UUID,
    owner_id UUID,
    shared_with_id UUID,
    PRIMARY KEY (tenant_id, owner_id, shared_with_id),
    FOREIGN KEY (tenant_id, owner_id) REFERENCES users.tenant_users(tenant_id, user_id),
    FOREIGN KEY (tenant_id, shared_with_id) REFERENCES users.tenant_users(tenant_id, user_id)
);

This schema ensures that all relevant data for the meeting scheduling application is captured and organized efficiently, with AI capabilities integrated to provide advanced features and insights.
