ERW is a set of specifications and tools that makes it easy to create, modify and maintain via web a database described by an entity-relationship schema.
Firstly, you describe the domain of interest using ERL, an XML-based language. Then ERW creates for you an SQL database, a set of customisable forms that edit the database, graphical layouts of the schema and documentation. Of course, ERW can be used for content management, in particular when your data is structured along complex relations.
In a way, ERW is a framework (in the object-oriented sense), as it provides a general infrastructure— you just have to "fill in the blanks" by describing the basic objects (entities and relationship) you want to manipulate.
Moreover, the limitations are overwhelmed by the advantages: you have to write no code. A description of an entity-relationship schema is sufficient to generate a complete application, or, as sometimes one says, ERW is able to perform a complete reification of the description. If you need to modify your schema, you just have to modify the description (migration of the database content, however, must be handled manually).
ERW provides support for many sophisticated schema features, such as multiple inheritance, weak entities with multiple owners, enumerative types, abstract entities, relationships with attributes, etc. Moreover, it provides useful end-user features, such as authentication and authorisation (even row-based), customisable labels and filters, internationalisation, UTF-8 support and so on. Ensuring coherence in such a generic setting required a very precise semantics of a schema, which is fully described in the manual and allows one to access the database and modify it using other clients.
