Products are coming, but there is a very limited selection at the moment. A list of specific products follows. Please keep in mind that I have not tried any of these products. My information comes reviews or vendor information. o RAIMA Corp. (Bellevue, WA. USA) makes a DBMS called db_VISTA. It has a front-end called db_QUERY which is a SQL interface. The limitations are that it is a network, not relational, database model; the SQL language is for retrieval only - update, insert, and retrieval are not allowed (but are coming in a year (maybe); and it is a c language interface intended for c developers who want to construct their own application and user interface. o Alisa Systems, Inc. (Pasadena, CA. USA) has a SQL database link called SequelLink. It allows a Macintosh to talk to a VAX/VMS host which has a SQL DBMS. The Mac side supports HyperCard and 4th Dimension as a front-end to the VAX/VMS DBMS. o Omnis 3 Plus version 3.3 (Blyth Software), due out in August, is supposed to support SQL. I don't have any specifics. o Oracle has has an A/UX system in beta trial. I'd be very interested in getting a summary of your responses.

I have used db_Query, and it has (to my mind) a lot of limitations. First, RAIMA advertises the product as "SQL BASED QUERY". It is not a subset of SQL per se, although the syntax is reminiscent of it. It adds a statement "relation" which specifies the explicit order in which the buffers should be filled. Fields are then "select"ed from that relation. Unless the new release changes it, joins are only allowed on set links and indexed fields. (I upgraded to the new version of db_Vista, but not to db_Query) To my knowledge, no query optimization is done. Make of all these scattered thoughts what you will.
