DrawSQL vs. ERDPlus vs. SQL Server Data Tools (SSDT) vs. django-mysql 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.

Django-MySQL extends Django’s built-in MySQL and MariaDB support their specific features not available on other databases. A new cache backend that makes use of MySQL’s upsert statement and does compression. Named locks for easy locking of e.g. external resources. Extra checks added to Django’s check framework to ensure your Django and MySQL configurations are optimal. Django-MySQL comes with a number of extensions to QuerySet that can be installed in a number of ways - e.g. adding the QuerySetMixin to your existing QuerySet subclass.
