这方面工作已经有人做了...请参考嵌入数据库，比如：SQLite当然还有其它数据库，可以根据具体情况来选择。下面是SQLite的官方简介（来自：http://www.sqlite.org/）-----------------------------------------------------
* Transactions are atomic, consistent, isolated, and durable (ACID) even after system crashes and power failures.
* Zero-configuration - no setup or administration needed.
* Implements most of SQL92. (Features not supported)
* A complete database is stored in a single disk file.
* Database files can be freely shared between machines with different byte orders.
* Supports terabyte-sized databases and gigabyte-sized strings and blobs. (See limits.html.)
* Small code footprint: less than 250KiB fully configured or less than 150KiB with optional features omitted.
* Faster than popular client/server database engines for most common operations.
* Simple, easy to use API.
* TCL bindings included. Bindings for many other languages available separately.
* Well-commented source code with over 98% test coverage.
* Available as a single ANSI-C source-code file that you can easily drop into another project.
* Self-contained: no external dependencies.
* Sources are in the public domain. Use for any purpose.
