DTM Data Modeler vs. ERDPlus vs. MySQL Data Access Components vs. WinSQL Comparison Chart

A database modeling tool for creating entity relationship diagrams, relational schemas, star schemas, and SQL DDL statements. ERDPlus is a web-based database modeling tool that lets you quickly and easily create Entity Relationship Diagrams (ERDs). Works with most contemporary RDBMS tools including Oracle, MySQL, Microsoft SQL Server, PostgreSQL, Teradata, IBM DB2, Microsoft Access, and others. The notation supports drawing regular and weak entities, various types of attributes (regular, unique, multi-valued, derived, composite, and optional), and all possible cardinality constraints of relationships (mandatory-many, optional-many, mandatory-one, and optional-one). The tool supports the quick creation of foreign keys and referential integrity lines by simple click-point-connect actions. This simplifies and quickens the process of creating relational schemas. The notation distinguishes fact tables from dimension tables by using a thicker frame around fact tables.

WinSQL is a powerful universal database management tool that is used by 90 percent of Fortune 500 companies and more than a million programmers and DBAs around the globe. WinSQL is a generic querying tool that connects to any relational database (RDBMS) for which an Open Database Connectivity (ODBC) driver is available, virtually all RDBMS on the market today. Connect to a variety of databases, including: heavy duty vendors Oracle, MS SQL Server, DB2, Sybase, Informix to lightweight backends like MS Access, DBase, and Text File. Generate royalty-free executables that can be used by your business users to run queries. These can be either static or dynamic queries that pull fresh data from the back-end. Export or simply open any query results into MS Excel with just a click of your mouse. You can even import an existing Excel spreadsheet to a database table by simply dragging an *.XSL file in the catalog tree.
