DbSchema Features

DbSchema is a database designer which includes besides layouts modules for SQL, Relational Data Browse, Query Builder and schema synchronization.

DbSchema DiagramsInteractive Layouts

Schema is represented in diagrammed layouts. Get a better understanding of the schema by creating multiple layouts, each focused on a specific part of the schema. The layouts and the schema structure will be saved in the DbSchema project file. Read more...
  • Edit tables or columns directly in the layout, by double-clicking them.
  • Create new foreign keys by drag&drop of one table column.
  • View database data by clicking the table header with SHIFT+CONTROL pressed.
  • Design schema offline and create it later in database
  • Different diagram look and feels
  • Draw foreign key line in table to table mode or pointing to each column
  • Use different foreign key notation: Idefix, Barker, etc.
  • Use for each table a different color, place comment callouts.

DbSchema Reverse EngineerReverse Engineer Schema From Database

New projects can be started by reverse engineering the schema from the database. The schema structure will be saved to project file and can be later reopened without connecting to the database.

From an created project you can connect to another database and synchronize the schemes. Like you would synchronize a development schema with the schema on a production database.

  • Connect to any relational database using JDBC drivers.
  • Upload any JDBC driver in DbSchema
  • Add a new database to the list of supported databases
  • SSH connections
  • Customize of queries to reverse engineer triggers, functions, procedures, constraints
  • Save of reverse engineered database schema to project file
  • Reopen saved project file without connecting to the database

Relational Data BrowseRelational Data Browse

An amazingly simple and efficient relational data explorer that offers simultaneous views of data from multiple tables and features numerous filters, data sorting mechanisms, and much more.

The data can be explored from multiple tables in the same time, based on the foreign keys between tables. Virtual foreign keys can be created. New records can be inserted, existing records can be edited. Read more...

  • Unlimited size of browse tree
  • Filter table data
  • Insert data in the browse table
  • Save browse tree in project file and reopen it later
  • Optimized memory usage
  • View Blob or Clob data from database
  • Easy way of searching data in the database
  • Printing

Query BuilderQuery Builder

Graphically compose SQL queries. You can make use of different join clauses like left outer join, use where filters or generate group by queries. Tables can be added by drag and drop or by pressing the foreign key icon. Read more...
  • Edit complex queries using the mouse
  • Select the query columns
  • Dynamically add new tables to the query
  • Use Group By conditions into the query
  • Set query Where conditions
  • Execute the query
  • Preview the query SQL

SQL EditorSQL Editor

Sql editor with syntax highlighting and code completion may help you to edit and execute SQL. It can execute simple queries as well as scripts. The output can be displayed on screen or spooled directly to a file. It can do graphical explain plan. Read more...
  • Edit queries using autocomplete
  • Highlight of SQL keywords
  • Execute single queries as well as scripts
  • Explain query execution plan
  • Use multiple result panes
  • Spool result to file as CVS, Excel, Tab delimited, etc

Generate Schema ScriptsGenerate Schema Scripts

In DbSchema you can generate the schema scripts and optimal export the data into script. Using the generated script you can recreate the schema on any database.

Compare Database SchemaCompare and Synchronize Database Schema

DbSchema is using its own image of the schema stored in the project file. Schema can be edited without connecting to database saved to file. Than connect to database ( can be a different database ) and synchronize the schema. Decide for each table, column, etc. which is missing on database or local project to create it or drop it on one side ( from database or from local project ). Read more...
  • Reverse engineer the database schema from database
  • Synchronize the database schema with the database
  • Choose for each difference found an action : 'Merge into local project', 'Change the database' or 'No action'
  • Generate a SQL script for the database modifications
  • Compare schemes from two DbSchema project files
  • Use DbSchema to update the database to the latest schema version
  • Have one central project and multiple databases
  • Convert the schema to a different database

Convert Database SchemaConvert Schema to a Different Database

Since the DbSchema project is independent from database you can change the project Rdbms in Project Properties. Than you can create or synchronize your schema with a different database. Changing the schema Rdbms will apply a new data type mapping for all columns, based also on the standard java SQL data types.

Data LoaderData Loader

Import data from delimited text, XML or Excel files into the database. Very easy to use, with data pre-validation.

Print Database DiagramSmart Printing

DbSchema can print the best layout images. You can also print the layouts as images or generate HTML documentation including small-size vector images.
  • Preview the printed pages
  • Choose a print zoom as well as the printed pages
  • Best print quality

DbSchema Explain PlanGraphical Explain Plan

The explain plan shows beside the original text returned by the database for the explain plan function a chart with the timeline distribution of the events. In the diagram are shown tips for each table or index access. This allows to easy identify the most consuming time events in the query and easy recognize the events which are accessing data.

Random Data GeneratorRandom Data Generator

Generate test data in the database. Configurable patterns including integer, random and reverse regular expression patterns can be used. A predefined repository of patterns will help in finding the best pattern for each column.

DbSchema DocumentationDocumentation

You can enter comments or call-outs for any of the schema tables, columns, etc. Moving the mouse over the layouts you will see this comments as tooltips. This may help you easy understand the tables and columns definition.

Using the feature of generating HTML documentation including SVG image of the layout you can post an interactive HTML documentation in your project or on the Web.

  • Two documentation formats: HTML5 or HTML4
  • Layout image included
  • Small size images through use of SVG
  • Interactive image. Move the mouse over columns in the image and read schema comments

DbSchema Project FileFlexible Application Interface & DbSchema Project File

DbSchema uses layouts to let you structure your work. Inside the layout you can have Data Browse Panes, SQL Editors and Query Builders. Saving the DbSchema project to file all of them will be saved. Opening the application next time will also open this editors.
  • Save one central project file including schema structure, layouts and editors for SQL and data browse
  • Open the DbSchema project from different computers
  • The DbSchema project file is in XML format and can be edited using an text editor
  • Multiple layouts and multiple editors for SQL, queries and data inside each of layouts
  • Reopen saved layouts or editors at any time
