CA's AllFusion ERwin Data Modeler r7: Page 4 of 4

CA has a few things to work on with AllFusion ERwin DM: forward engineering support for MySQL, for example. MySQL 5.0 is a breakthrough product release, has become increasingly popular and is therefore a real contender in the DBMS arena. Also, the product's process for establishing a recursive relationship--that is, an entity with a relationship with itself--is not as intuitive as establishing a relationship between two different entities. Database designers don't think of recursive relationships as being different from nonrecursive ones, so the process shouldn't be implemented differently. Last, the creation of supertype and subtype relationships is clumsy. Conversations with CA support personnel confirm that many of these issues are being addressed and slated for future releases.
