- Q These days, if it isn't web integration it's probably talking to a database -often it's both. Although database APIs (ODBC, OLE DB, ADO, RDO, JDBC) offer some cross system compatibility, each RDBMS seems to use enough of its own SQL language variants, data types and reserved words to make migrating from one to another painful -even with the 'upsizing tools' some products come with. A commitment to a database vendor needs to last number of years, often longer than the lifespan of individual applications or web pages. Don't rush into a decision, and experiment before you commit. Microsoft Access is the ubiquitous poor man's relational database. It's great for small apps, easy to develop on (wizards + visual basic + SQL ) and the run time version is redistributable. The run time is fairly lightweight, except when it goes into a 100% cpu time spin cycle, which is rarer on Access 2K than older versions. A lot of apps use Access behind the scenes, even the ill fated WebTV for Windows that shipped with Win98.0. MS SQL Server is a more serious beast -SQL server is actually usable in anger on big commercial servers, and has lighter weight 'personal' and run time only installations -the latter being redistributable. The load that SQL server places on any system limits its value as a competitor to MS Access as a redistributable component with a third party app, but it’s a better choice for a production system. Although it needs NT to work properly, and is so ultimately limited in throughput and scalability, the cost of SQL server is not bad compared to that of other database vendors. Scalability is probably its greatest weakness -most of the 'DNA' documents coming out of MSDN seem to be workarounds to deal with NT's scalability limitations, usually using cloning and distribution to substitute for high end metal. Borland Interbase comes with many of the Borland products, so is your obvious choice with Delphi/C++ builder. Now that it is open source on sourceforge under the Interbase and Firebird projects, it will have a viable lifespan and a great price. Sybase and Informix sell common databases, while IBM have a scaled down version of their DB2 behemoth that runs on NT as well as 390 series mainframes. Almost all the big commercial web sites use Oracle. That's mostly due to the fact that the Oracle/Unix combination scales up nicely, rather than from a great appreciation of what is indubitably another legacy nightmare full of the scar tissue of the previous eight versions, with everything from an internal ADA like language engine to all the kluges you need to get the system to run on everyones' hardware. And have you noticed looked at Oracle web sites for pricing? They have this funny model where you pay in direct relation to your CPU power, which kind of hurts given the speed of Intel parts these days. But developers get free copies for the pre-deployment phases of development. Very finally, MySQL is the bottom feeder of the database land, lightweight and free on Linux for a long time. The Windows version used to cost (to cover the higher development expenses of windows), but since going open source the later builds for win32 are now free. Low end Linux ISPs love this DB because of its minimal load, and if you are doing DB work targeting deployment on such an ISP then its important to have locally. But otherwise it has little to recommend it.
