DbSchema Features

Connect to any Database & Reverse Engineer the Schema

Start a new model by reverse-engineering the schema from the database. The model contains a database-independent image of the schema.
Documentation

  1. 1
    Connect to any Database

    Using JDBC drivers you can connect to any database and reverse engineer the schema.

  2. 2
    Connect to Cloud Databases

    In the cloud database console, you will find the JDBC URL. In DbSchema tick the 'I know the JDBC URL' checkbox and copy the URL.

  1. 3
    Automatic JDBC Driver Download

    Choosing a database DbSchema will automatically download the JDBC driver from the driver repository. This requires Internet connectivity.

  2. 4
    SSH Connections

    Work on your database through secured connections.

Reverse Engineer the Schema

Logical & Physical Design

The logical design is a database-independent design, with entities and many-to-many relations. From the logical design you can generate physical design.

  1. 1
    Use Different Relations

    In the logical design, you can create identifying, non-identifying, one-to-one or many-to-many relations. In the physical design, the foreign key cardinality is determined by the referring column uniqueness and mandatory properties.

  2. 2
    Use Shapes

    Can add different shapes and arrows to the layout.

  1. 3
    Use Conversion Rules

    The conversion of the logical design to physical can use convertors to map the data types, attribute and entity names, default values, etc.

  2. 4
    Share the Design in a Team

    The logical design is saved to the model file and can be shared in a team.

Database Logical Design
