最近几年来,地理信息系统无论是在理论上还是应用上都处在一个飞速发展的阶段。 GIS被应用于多个领域的建模和决策支持,如城市管理、区划、环境整治等等,地理信息成为信息时代重要的组成部分之一; “数字地球”概念的提出,更进一步推动了作为其技术支撑的GIS的发展。 与此同时,一些学者致力于相关的理论研究,如空间感知、空间数据误差、空间关系的形式化等等。 这恰好说明了地理信息系统作为应用技术和学科的两个方面,并且这两个方面构成了相互促进的发展过程。
SQLite is a software library that implements a self-sufficient, serverless, zero-configuration, transactional SQL database engine. SQLite is the most widely deployed SQL database engine in the world. The SQLite source code is not subject to copyright restrictions.
This tutorial will show you how to program with SQLite and get you started quickly.
现在开始学习 SQLite! This tutorial helps beginners understand the basics and advanced concepts related to the SQLite database engine. Before you begin to practice with the various examples provided in this tutorial, you need to understand what a database is, especially RDBMS, and what a computer programming language is. If you want to compile / execute SQL programs through SQLite DBMS, but you do not have the relevant settings, you can visit the compileonline.com . You can experience real programming experience on a high-end server with a simple click. This is a completely free online tool. This tutorial provides a reference manual for all the important built-in SQLite functions. This tutorial lists SQLite database websites and books. SQLite Home Page -the official SQLite website provides the latest SQLite installation, the latest SQLite information, and a complete SQLite tutorial. PHP SQLite3 -the website provides full details of PHP support for SQLite 3 databases. SQLite JDBC Driver: -SQLite JDBC, developed by Taro L. Saito, is a library for accessing and creating SQLite database files in Java. DBD-SQLite-0.31 -the SQLite Perl driver driver is used with the Perl DBI module. DBI-1.625 -the Perl DBI module provides a common interface for any database, including SQLite. SQLite Python -the sqlite3 python module is written by Gerhard Haring. It provides a SQL interface compatible with the DB-API 2.0 specification. 1.1.1. Who is suitable for this tutorial? ¶
