- Margo suggested to take a look at the database library from Berkeley.
- It contains a hashed access method, btrees, and a record number package
- (built on top of the btrees). It is available via anonymous ftp from:
-
- okeeffe.cs.berkeley.edu.
- /pub/db.tar.Z
-
- This package looks pretty good, I haven't had luck in compiling it just
- because my make utility is brain-dead (AIX, I love you! AAARRGGGHHHHH!
- Sorry...8^). It doesn't provide any form of record locking or transaction
- management.
-
- Ted mentioned that Rogue Wave sells a C++ class library for UNIX/MSDOS
- that contains a Btree on disk. He says it works fine with Windows 3.1 also.
- They provide full source (as an option). I haven't had the chance to
- check on this product.
-
- Bruce mentioned MetalBase, a product I had seen before. It is available
- from most archives. The current release is 4.0 (as far as I know), the author
- is Richid Jernigan IV (richid@owlnet.rice.edu). From what I can recall,
- it implements relations on disk using AVLs in a very efficient manner,
- including multiuser access. Metalbase is shareware.
-
- Art mentioned the C Database Toolchest by Mix Software. The toolchest
- comes with a good B+tree as well as a good ISAM library. It also comes
- with a 300 page manual (or so) and is quite well documented. Price is
- $19.95 for the manual and library files and another $10 for source. I
- called Mix Software and asked them about multiuser support; they are
- working on it, and their gesstimated release date is somewhere within
- the next four months.
