gt8963a@prism.gatech.EDU (MCCARTNEY,JEFFREY ELWOOD) (11/19/90)
I'm searching for mature DB's that have BLOBS (datatypes that handle images,etc)
on the VMS operating system. I'd also be interested as to what programming
languages they interface with.
And also how long (time and releases) the blob feature has been out.
And also, if you've experience with the DB software, how is it in general and
how professional the people behind the product are (or are not)
I thank you
Jeff

DEC's own Rdb supports blobs (DEC calls them "segmented strings"), as does Interbase from Interbase Software. Both have programming interfaces for all VMS languages (C, FORTRAN, etc.) As for maturity, both Rdb and Interbase are fairly mature products, having been around for at least a couple of years. matt -- Matthew Reedy UUCP: uunet!iquery!matt Programmed Intelligence Corp.

The are called "segmented strings". A DEC-internal group has been using them for images for some time now. Bob Devine

Blobs can be of the text or binary variety. As for support, I found it difficult to find someone at Informix that had actually used BLOBs. We are now successfully using text BLOB's for message delivery without any problems. Naomi -- Naomi Walker (aka N7FSA) Anasazi Inc.

Empress, which runs on VMS and on UNIX, supports blobs. Empress calls this data type "BULK". Empress also allows C coded extensions to SQL. So you can create new SQL operators or functions that operate on your bulk attributes. Then you may include these function calls in SQL statements, anywhere that you may place an attribute expression, that is, in projections or in "where" clause selection criteria expressions. I have implemented my own user functions in Empress SQL and they worked very well. Once implemented, they are easy and satisfying to use. But, the developers interface is complex and the C coding and various table setups are not simple. > I'd also be interested as to what programming >languages they interface with. > C, their $GL "Mbuilder", (maybe COBOL and others). >And also how long (time and releases) the blob feature has been out. > Empress has supported blob (bulk) data for at least 4 years. >And also, if you've experience with the DB software, how is it in general and >how professional the people behind the product are (or are not) > My version of Empress (V2.4) was basically solid. But, it was not based on client/server architecture and I need that. Also, it was not very good for multiple simultaneous users. There were too many (logically unnecessary) locking conflicts when the usage was heavy. I understand that these problems were addressed in the version released in the first quarter of 1990. -- Satyabodhi | Domain: bodhi@idun.ISC-BR.COM | UUCP: ...!uunet!isc-br!idun!bodhi

Interbase (also known as Starbase from Cognos) has extended the basic blob type to allow user defined blob types and filters . The filters can be written in a 3gl. Other basic blob operators include for loops, blob load and dump (to external files) blob edit and c style getb,putb calls . The Interbase Gdml language which supports blobs allows you to incorporate blob handling into Sql programs : blobs are also part of the transaction control . Preprocessor support exists for Ada , Basic , C , Cobol , Fortan , Pascal and Pl/I . I would interested to hear about what people use blob type structures for beyond holding just lots of text . -- Nigel Campbell Voice: (613) 783-6828 P.O.
