The best SQL query tool to visualize data relationship

Bay Breeze Software just released SQL Edge 1.4, please refer to
http://www.baybreezesoft.com for product details.

SQL Edge is an Eclipse Rich Client application that allows users to
execute SQL queries, browse schema information in ER diagrams, and
visualize data relationships. With SQL Edge?, users can use only one
query to retrieve data in a master table, and then browse data in all
related detail tables. Users can also insert, edit, and delete table
records in the data grids.

SQL Edge? has five perspectives. The "Query Perspective" allows users
run any SQL queries, while the "Schema Perspective" displays table
schema information.

There are two relationship perspectives. The "Relationship Table View"
displays data in the master-detail style. The "Relationship Tree View"
displays master table records as top-level tree nodes. The nodes can be
expanded to reveal any level of related detail records. In addition,
clicking any node will display the corresponding data in a detail grid.

The "Model Perspective" displays tables and their relationships in ER
diagrams. The tables can be from different databases. Users can define
master-detail relationships among these tables, and print or save the
diagram for future reference.


The version 1.4 added following features:

(1) Added support for synonyms and CLOB data type.
(2) Added load on demand feature to support large result sets. In query
perspective and relationship table view, a selection query will only
fetch enough rows to populate the data grids. Users can scroll down the
grids to fetch more rows if needed.


The version 1.3 added following features:

(1) Added model perspective to display tables and their relationships
in ER diagrams. The tables can be from different databases. Users can
define master-detail relationships among these tables, and print or
save the diagram for future reference.


The version 1.2 features are:


(1) Support any JDBC compatible databases.

(2) Allow users to specify JDBC drivers at run-time, and provide
wizards to help setup JDBC connections. Easy to install, and easy to
setup.

(3) SQL editor with syntax highlighting based on currently connected
databases.

(4) SQL edtior allows users to execute SQL queries asynchronously.
Users can cancel the execution by click the "Cancel" button or just
close the SQL Editor.

(5) Schema perspective displays the table schema information, including
column definitions, primary key, indexes, and foreign keys.

(6) Relationship table view displays the related data in the
master-detail style, with master table data shown in the top grid, and
all related detail table data in a list of bottom grids.

(7) Relationship tree view displays the master table records as
top-level tree nodes, and the related detail records as child nodes.
Click any of these tree nodes will display the corresponding record
data in a detail grid.

(8) Allow users to insert, edit, and delete records in the master and
detail grids of the relationship table view and relationship tree view.


(9) Allow users to define master-detail relationships even between
tables in different databases. This enables the relationship table view
and relationship tree view to display data relationships between tables
in different databases or without pre-defined foreign keys.
