JSDB 介绍
JSDB 是 JavaScript 用来访问数据的开发包，是一个数据驱动的脚本语言，支持数据库、XML 和 Web 以及 Email。
JSDB is based on Mozilla SpiderMonkey and class libraries developed by
Raosoft, Inc. The open-source version is free with fairly generous license
terms. Additional functionality or even less restrictive license terms may be
purchased from Raosoft, Inc.
JSDB can treat any DBF/xBase, ASCII, Oracle, Sybase, DB/2, Postgres, MysqL,
Access, or Microsoft sql Server table equivalently, translating high-level
(set(row,field,value), get(row,field)) function calls to database-specific
sql commands. The same applies to email: you can communicate with Lotus Notes,
Exchange (MAPI), and SMTP/POP3 mail systems interchangably with a single set
of function calls.
JSDB also includes a stream object that gives you a common interface to files,
COM ports, sockets, HTTP, pipes, and memory. The ability to treat memory as if
it were a file helps you write reusable code that is easily adapted to a
variety of situations.
For writing distributed XML web applications, JSDB comes with an Internet
server component and an XML parser, both implemented in a balance of C++ and
JavaScript for optimum speed and flexibility.
You might use JSDB to:
- translate XML into sql statements,
- translate sql databases into XML,
- generate HTML documentation from an XML or Oracle database,
- download web pages while you sleep,
- index their contents in a database,
- send personalized email based on a database,
- or run a web database
