Metakit Description

Metakit is an efficient embedded database library with a small footprint. It fills the gap between flat-file, relational, object-oriented, and tree-structured databases, supporting relational joins, serialization, nested structures, and instant schema evolution. There is a C API, a Python binding called Mk4py, and a Tcl binding called Mk4tcl (with an optional OO binding on top called Oomk). You can manipulate and exchange data between any of these.

- Use your data on any platform - Both the code and datafiles are portable. All byte-ordering managed by the library.
- Complex datastructures in one file - Store multiple nested data structures, to create document-centric applications.
- Restructure datafiles, instantly - You'll have to see this to believe it: restructure files on-the-fly, while open.
- Serialize all data for transport - Complementing commit/rollback of changes, data can also be serialized.
- Recover from system-failures - The use of Stable Storage ensures that files cannot be corrupted by crashes.
- Load on-demand, quick startup - Files are opened without reading data. Memory-mapped files if O/S supports it.
- Behaves like containers - The API mimics container classes. Quickly get sizes and iterate over rows.
- Wide range of operators built-in - Sorting, relational join / group by, set operations, permutations, hashing.
- 1-32 bits per int (or 64), variable-sized data - The largest int defines storage format. String/binary data is stored as var-sized.
- Create fully self-contained applications - Can be linked shared or statically, for hassle-free deployment of components.
- Tiny code (125 Kb as Win32 DLL)
- The library is extremely small, unused functions are stripped off in static links.
- Simple API, just 6 core classes - Only a small interface is exposed. One header file lists all the classes you need.
- Also use from Python and Tcl - These language bindings are coded to take advantage of the respective idioms.
