You can take a look at sqlite
(http://www.sqlite.org/). It doesn't require a client
server setup, and offers you the same sql syntax for manipulating data on

Some amazing facts about this from the website:

SQLite is a small C library that implements a self-contained,  
embeddable, zero-configuration SQL database engine. Features include:

* 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.
* A complete database is stored in a single disk file. 
* Database files can be freely shared between machines with 
  different byte orders. 
* Supports databases up to 2 terabytes (2^41 bytes) in size. 
* Sizes of strings and BLOBs limited only by available memory. 
* Small code footprint: less than 30K lines of C code, less
    than 250KB code space (gcc on i486) 
* Faster than popular  client/server database engines 
  for most common operations. 
* Simple, easy to use API.
* Well-commented source code with over 95% test coverage.
* Self-contained: no external dependencies. 
* Sources are in the public domain. Use for any purpose.

The SQLite distribution comes with a standalone command-line access
program (sqlite) that can be used to administer an SQLite database and
which serves as an example of how to use the SQLite library.
