Documentation and media

Captions are in English; the application UI is in Ukrainian. See the main README for context.

Screenshots

Captured from the running application.

screenshot-chat.png

The main window. Chat list on the left, active conversation on the right. Messages sent by the signed-in user are right-aligned and unprefixed; messages from others are left-aligned and prefixed with the sender's login. The last message from olga carries a file attachment, rendered as a card with a download button.

screenshot-drawer.png

The left navigation drawer, signed in. The profile card shows the user's initials and login; below it are Create new chat, Contacts, and Settings.

screenshot-theme.png

The palette picker (Колір інтерфейсу). The full Material Design swatch set with primary and accent hues, plus a light/dark toggle. Selections apply to the running application immediately.

Diagrams

Both were drawn in 2019 as part of the project's design documentation.

diagram-er.png

Entity-relationship diagram of the database. A User is projected into four role tables — Administrators, Participants, Senders, Receivers — which in turn associate with Chats and Messages. ParticipantChats and ReceiverMessages are the join tables. Files shares a primary key with Messages as an implicit one-to-one association.

Verified against the schema Entity Framework actually generates: 11 tables including __MigrationHistory.

System data-flow diagram, showing the two information domains (user data, chat data) and the operations against each. Labels are in Ukrainian. Reading key:
