Visualize, modify, and build your database with dbSpy!

An open-source data modeling tool to facilitate relational database development

New Features with Version 7.0

-UI is now full widescreen with a drop down menu to allow for more workspace. -The Save, Load, and Delete features now take filename, and can save schema, and data. -Deleting certain elements in tables now locates, and also properly delete depedent elements on other tables -Implemented an algorithm to highlight all edges connected to currently selected table -Fixed several Issues where certain Elements would not be deleted from a connected database -Fixed several Issues with show Data terminating react flow -Fixed several Issues with Edges being rendered too many times, and not deleted

Use Cases

  • Connecting to an existing remote PostgreSQL, MySQL, MicroSoftSQL, OracleSQL databases
    • Renders an ER diagram for SCHEMA and DATA of the existing database and provides an interface for users to both modify existing tables and create new tables. A log of changes is stored, and at any point, the user can generate a query containing the changes, such that they are reflected in the existing database.
  • Uploading your database's SQL file
    • Renders an ER diagram for the provided SQL file (db dump) and provides an interface for a user to both modify existing tables and create new tables. Changes are converted into the corresponding queries, which the user can view and execute on their own database outside of dbSpy.
  • Seamlessly visualize relational databases (both SCHEMA and DATA)
    • After connecting database tables with one another, users are able to render the relationship connections of individual tables by clicking on the tables.
  • Creating a database + ER diagram from scratch
    • Provides a canvas for users to create a database by using ER diagrams, thus creating a blueprint for engineering database structures.

Key Features

  1. Database Uploads: Connect to remote SQL database or upload local SQL files

  2. ER Diagram Visuals: Visualize the entity relationship diagram of a database with dynamic handle placement

  3. Table Relationship Visuals Relationships of individual tables are easily identified when clicking on a table

  4. Schema Modification: Toggle between Schema and Data easily with a click of a button

  5. Data/Schema Modification: Easily modify a database's schema or data through a simple UI

  6. Guided Database Building: Create a new database from scratch using entity relationship diagrams to ensure the integrity of the database

  7. Database Undo/Redo: Provides a history of edits for easier backtracking

  8. Query Generator: Query generator generates executable SQL queries

  9. User Sessions: Sign up/Log in securely with either Google/Github OAuth or JWTs/Bcrypt

  10. Save/Load: Store and reload past database sessions through your user accoun

  11. Dark Mode: Visual settings to provide a more comfortable viewing experience in low-light environements

Getting started

You will need your own MySQL database for backend functions.

  • Fork and clone this repo
  • Add a db_schemas folder in server directory
  • Add a .env file to the root directory with the information below:
# production environment variables
USER_DB_URL = <MySQL url for storing user data>
USER_DB_USER = <user string from USER_DB_URL>
USER_DB_PW = <password string from USER_DB_URL>
TOKEN_KEY = <any string>

# testing environment variables
## encoded SSL data required for GitHub Actions
SSL_KEY = <base64 encoded SSL key (see SSL Configuration)>
SSL_CERT = <base64 encoded SSL cert>
## MySQL and Postgres databases to test remote connection functionality
MYSQL_TEST_URL = <MySQL url for a test database>
MYSQL_TEST_USERNAME = <user string from MYSQL_TEST_URL>
MYSQL_TEST_PW = <password string from MYSQL_TEST_URL>
PG_TEST_URL = <PostgreSQL url for a test database>
PG_TEST_USERNAME = <user string from PG_TEST_URL>
PG_TEST_PW = <password string from PG_TEST_URL>
## test user with saved schema to test save/load functionality
TEST_USER_EMAIL = <email string>
TEST_USER_PW = <password string>

GOOGLE_OAUTH_CLIENT_ID = <Google Oauth client id>
GOOGLE_OAUTH_CLIENT_SECRET= <Google Oauth client id>
GOOGLE_OAUTH_REDIRECT_URI = 'http://localhost:8080/display'

GITHUB_OAUTH_CLIENT_ID = <Github Oauth client id>
GITHUB_OAUTH_CLIENT_SECRET= <Github Oauth client id>
GITHUB_OAUTH_REDIRECT_URI = 'http://localhost:8080/display'
  • Run the following below:
$ npm install
  • Execute the following command to populate your mySql database with a users table:
$ npm run seed
  • Run the project in development mode:
$ npm run dev

SSL Configuration

To connect with the SQL database, we must create and configure SSL certificates.

Mac

  1. Install mkcert; you can learn more about mkcert here
npm install -g mkcert
  1. Run the following script
npm run cert

Linux

  1. Check mkcert is up to date (v1.5.1 as of publishing)
mkcert --version
  1. Run the following script
npm run cert:linux

  1. Click on the "Connect Database" button under the Action section on the left side of the page. This will open a sidebar on the right side of the page.
  2. Select the database type from the dropdown.
  3. Input your database URI information OR database connection credentials and click on "Connect".
  4. Once the connection to your database is established, the canvas will render and generate the tables and their relationships.
    • OracleSQL requires the download of the OCI - here
