Itzam it's a library that creates and manipulates files containing variable-length, random access records. Information is referenced by a user-defined key value; indexes may be combined with or separate from data.

Itzam is a deliberately portable, low-level C library that can (and will) be wrapped in C++, Java, Python, and Fortran 95. Higher level languages implement more complex heuristics on top of the Itzam core functions.

Here are some key features of "Itzam":
Small Footprint

Itzam Core adds less then 6K bytes to a program when linked statically.

Portability

Itzam is deliberately portable across operating systems and platforms. A database created on Windows is readable by an Itzam application on a Linux machine. The current release ships with support for building and testing on Unix, Linx, and Windows operating systems.

No Dependencies

Itzam does not have any dependencies on external libraries or components, beyond the common elements included with every Standard C compiler.

Flexibility

Build your databases with indexes embedded in data files, or separate key information for the data it references, to provide different indexing schemes for different purposes. Iterator selectors provide flexible filtering to define subsets of a database.

Dual Licensing, GPL and Commercial

Itzam can be licensed under either the GNU General Public License (GPL) or a simple non-free (closed-source) license. The GPL version is provided as is without support, while the commercial license provides technical assistance and notice of updates and bug fixes.

64-bit File Access

Itzam is designed with 64-bit addressing in mind, and works with 64-bit Sun Solaris and 64-bit Linux.

C++, Python, and Fortran 95 Abstractions

The core library, written in ANSI C, operates at a low-level, working directly with the operating system. While a low-level library can be a powerful tool for embedde3d and small systems, large-scale projects can benefit from a higher-level of abstraction. Development and testing is underway for C++, Python, and Fortran 95 "wrappers".

Documentation

I've written tutorial and API documentation to accompany Itzam. A complete example application, a contact database, is the basis for the tutorial.

What's New in This Release:
Minor optimizations and code clean-up.
