A "Real" Database and Benchmarks 
By Kirk Chase, Editor
A “Real” Database Comes to the Macintosh
Joseph S. Terry, Jr., President

Oxnard, CA
Developers in the Macintosh world are at a disadvantage. Programmers on other platforms have had a much greater choice of tools for a long time. Reading through MacTutor’s advertisers index one finds MACYACC from Abraxas Software. This tool is based on Yet-Another-Compiler-Compiler (YACC) from the UNIX world. YACC has proven itself over some 15 years to be an extremely valuable tool. I welcome it’s cousin on the Macintosh. Language Systems’ Fortran, a language where it can truly be said, “You had to be there!”. The “there” part was “in the beginning”. I welcome the “Old Man” or “Old Woman” of computer languages to the Mac.
Although I don’t want to endorse any particular product, we must realize that other platforms have a great deal to offer the Macintosh. Remember that those old guys and gals really DID know something.
It seems that some Mac programmers think that really “neat” programming only began in late ’81, continued through ’82 and ’83, and culminated in the release of the world’s FIRST computer in ’84: Macintosh!
I had hoped that the product I chose to debut as a serious quasi-horizontal Mac developer would be less controversial (and more polished) than it is. But, that is not to be.
The Mousehole Report of November 1990 contained a memo which raised some uncomfortable points about my new product, and I would like to set the record straight. Whenever we are driving and I say, “Should we go straight?”, my friend Kenneth from Oklahoma says, “Don’t go straight, go forward!”. As I go forward into the future, I would like to say to everyone who reads MacTutor, I am very glad to be here!
My partner, Adam R. Joyner, Chairman/CEO, and I have formed a company called Ajalon Corporation. We have become the exclusive resellers, support and developers of db_Vista III for the Macintosh from Raima Corporation of Bellevue, Washington. db_Vista III is a database system for C programmers composed of three main modules; db_Vista, db_Query and db_REVISE. db_Vista is the actual database engine. This engine is available for THINK C and MPW C currently. The source is available at a very reasonable price. Less than $1000.00 for a complete single user system with source included. We have plans for a HyperCard XCMD version, and similar “glue” for THINK PASCAL, MPW Object PASCAL (read MacApp) and, yes, FORTRAN.
db_Query is a complete report and query application based on a subset of SQL. With db_Query the user or programmer can perform arbitrarily complex queries using the english-like SQL language and store the information obtained in it’s new format.
db_REVISE allows the developer to reorganize the database. Add, change or delete files, fields, keys, compound keys, or sets and retain the data already in the database without cumbersome exporting and importing. Using an advanced Revision Description Language(RDL) data can be merged from different databases into a third hybrid, on the fly, under program control.
In the November 1990 Mousehole “Mikev” talked about db_Vista. He said “ ... I don’t recommend these products ...”, chilling, and further “ ... The source is just about worthless: it is largely uncommented, undocumented, and unstructured.”
Ok. one at a time. Yes, It is hard to recommend these products given the kind of neglect that the Macintosh version has been subjected to. The product had not been updated in over a year before Adam joined Raima in February ’90. Adam was their sole “Mac Guy” most recently. All the other db_Vista developers were bred in the UNIX and DOS worlds and knew very little about the orphaned Mac product. In their defense, Raima was justified in letting go of the Macintosh version . The UNIX and DOS database tools markets are TEN TIMES the size of the Mac marketplace and has been their bread and butter. Believe it. That’s THEIR focus, NOT ours. We are the Macintosh evangelist for db_Vista, if you will, and we think you would be amazed if you knew the whole truth. FACT: The db_Vista III development application doesn’t run well under MultiFinder. FIX: WaitNextEvent vs. GetNextEvent. FACT: To import data an application is sublaunched and then returns to the caller. FIX: Not necessary. It Works! It is a decidedly UNIX/DOS way of looking at the problem, but it works!.
We will be integrating these tools into the main application and providing more of the Macintosh “Advantage” as soon as we can, but don’t let that hold up serious development tasks. The basic database technology is solid and has YEARS of proven reliability in the PC and Unix world. Remember, one of db_Vista’s strengths is it’s cross platform portability, which supports DOS, Windows, Unix and VMS environments; an important feature in today’s heterogeneous development environments.
Adam and I are committed 110% to making all the right changes in the product to make it a contender for 1st place in the Mac developers heart. db_Vista is very fast. It was bred in a world where memory is precious. Therefore it simply opens its wings and soars on a Mac with One megabyte of memory. Try that with 4th Dimension.
Regarding technical support, yes, Raima did have problems with supporting the product. Throughout the history of the product they never allocated the resources or talent necessary to provide even adequate support to customers. We, on the other hand, are committed to superior technical support. This is critical when dealing with a product aimed at the developer community. Developers have a high degree of intelligence and need sophisticated support. They also have deadlines and can’t afford to waste time with wishy-washy responses. If a problem occurs we need to fix it. Immediately.
“ ... largely uncommented, undocumented, and unstructured ...”, Yes the source is large and not the prettiest. But, this is not a NEW database just released to the world. The Mac version just needs some special care that an experienced Mac/UNIX/DOS programmer can give before it will be humming. Raima didn’t understand the Mac or the 68000, but WE DO! Also, the source code was intended for customers who wanted to perform MAJOR changes to the basic db_Vista technology. Unfortunately, a lot of customers had to resort to using the source to debug problems in the db_Vista product. Now that we have the product WE will fix the problems, not the customer.
Besides, I wonder if “Mikev” has attended the developer classes that Raima holds each and every month all over the world. The Basics class, the Advanced class, and the Internals class. Each class is $300.00 per day. Two days for Basics, one for Advanced, and two for the Internals. This is a serious, relatively bug free and well respected database in the UNIX and DOS worlds. The Macintosh lags behind, but we intend to change that.
db_Vista has zero(0) user interface tools and that’s the way we like it. Use MacApp, THINK Class Library, AppMaker, Prototyper 3.0, HyperCard, SuperCard, or MacWorkStation to build the user interface. We will handle the database portion for you. db_Vista has powerful network model features that enable db_Vista to outperform nearly every other relational database, yet the relational database features are there for those times when it’s most appropriate.
db_Vista is a good tool. It was never brought over to the Mac with TLC. We will give the product that care, thought, and time. If you bought it, contact us and see the future. If you haven’t, then call us and “Let us show You”. (I love that line.)
Well, overall I couldn’t blame “Mikev”. Mac products need developers who care about the Mac, who understand it’s complexities and appreciate it’s simplicities. Adam and I feel that we can earn your support and your development dollars.

Response to “Benchmark Challenge”
David T. Craig
Kansas City, MO
I would like to respond to the letter by Walt Davis and Steve Bayer (MT, Sept. 1990, p. 4+) titled “Benchmark Challenge”.
Note: Source code files accompanying this letter are located on MacTech CD-ROM or source code disks.
After compiling the Davis/Bayer IF-THEN-ELSE and CASE statement routines in MPW Pascal 3.0 I obtained the following execution time results:
When compared against the Macintosh II results in the letter obtained using the THINK Pascal 2.0 compiler MPW Pascal 3.0’s execution times are very similar. My complete source code for the MPW Pascal program are enclosed along with a listing of the generated assembly code. Note that the assembly code showed the IF-THEN-ELSE routine consisting of a sequence of comparisons. The CASE routine showed that MPW Pascal generates a lookup table containing the offsets of the CASE routines. I did not test MPW C 3.0 since I’m not a C programmer.
Davis and Bayer made an excellent statement in their letter about a topic which in my opinion has long been misunderstood by many programmers. They say “the relative speed of a high-level language depends on the assembly language produced by the compiler and not the high-level language itself.” As Davis and Bayer demonstrated, their THINK C code ran slower than their THINK Pascal code even tho everyone “knows” C is faster than Pascal. Niklaus Wirth, the designer of Pascal and Modula-2, stated many years ago that judgments upon the execution speed of computer languages are nonsense since it’s the implementation of the languages that is crucial in execution speed, not the language design. Wirth in the early days of Pascal (c. mid-1970) created a Pascal compiler at ETH, his Swiss university, that produced faster code than the university FORTRAN compiler. And everyone “knows” FORTRAN is faster than Pascal!
One last comment. Davis and Bayer’s source code should not use the Macintosh ROM call GetDateTime() for benchmarking purposes. This call returns the current system time in units of seconds. For benchmarking purposes they should use TickCount() which returns its time in 1/60 of a second, a finer granularity which is more accurate.
