- this is to announce that
-
- MOOD4-PC: {Material's, Miniature} Object-Oriented Database
- system program for IBM/NEC-PC
-
- has been made ftp'able from
-
- mood.mech.tohoku.ac.jp (130.34.88.61)
-
- we will appreciate your continuing interest on our project. the
- following is its release note:

- %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
-
- MOOD4-PC ver.1.00, preliminary release-note
- DEC 24, 1992
-
- Merry Christmas, by the way.
- ====================================================================
-
- MOOD4-PC ver.1.00:
- Material's/Miniature Object-Oriented Database Prototype for
- NEC/IBM-PC,
-
- is an object-oriented database system program. our last program
- MOOD/P3-PC was an approximate copy of MOOD/P3. it was so made in the
- hope that many poeple, who can not run the program exclusively for
- NEC/PC-9801, would feel the MOOD. although we have found not least bugs in
- MOOD/P3-PC, we have dicided to develope it further, rather than to fix
- up all those bugs within the functionalities attached to it. let us,
- then, enumerate the new features of the present release, which is
- newly named as MOOD4-PC. we think the program deserves this name.
-
- 1) support of homonym and synonym.
- different classes with the same name are distiguished by their
- superclasses, synonyms, and their slots. this saves us from the
- unnatural naming of classes otherwise necessary in order to put
- everything a unique name through out the database. the problem of
- system reserved words has also been solved.
-
- 2) summary class
- we have invented a summary class which holds a table of data
- points which have been obtained a series of experiments. this saves
- the load of inputting data and storage space. also this form of
- recording conserves the implication embedded in the summarized data
- such as an interesting correlation between a experimental parameter
- and result. the summary class object, yet, matches the query made
- direct to the description of the experiment.
-
- 3) summarizing
- for a set of data objects which matched a query, we can invoke a
- "summarize" session in which we can edit a template object and execute
- the session. with this, we can extract and tabulate any parameters
- embedded in the individual retrieved objects. the obtained result can
- be written out to a file for the processing with other program, such
- as spread sheet. this functinality is a counterpart of query language
- such as SELECT-FROM-WHERE and better than this at least in some way:
- SELECT part, FROM part, and WHERE part are all editable in the
- summarize session. you can repeat edit/execute until you get
- satisfactory results.
-
- in implementing these, the user-interface has been subjected to
- some change. we are, therefore, to prepare documents which describe
- these new features and operation of MOOD4. the basic functionalities,
- however, are inherited from MOOD/P3 and MOOD/P3-PC so that the manuals
- for them in ../doc will still be mostly valid. for the time being, the
- manuals, nemu display and some imagination will help you to enjoy (or
- struggle with) this program.
-
- as same as the previous MOOD/P3-PC, this release is made in the
- form of source program files to be consulted and run on Arity/Prolog
- interpreter. the program is supposed to be portable among NEC/PC-9801,
- its clones/IBM-PC and its clones with MS-DOS and Arity/Prolog
- Interpreter. We could have tested this on:
-
- 1) NEC/PCs with MS-DOS 3.3
- 2) a nameless IBM-PC clone machine with MS-DOS/V, both in
- Japanese and English modes. ANSI.SYS must be included in the
- configuration.
-
- We hope you will enjoy this program. mails telling bugs,
- inconveniences, objections will be appreciated.
