数据预测算法，主要是一元n次方程的回归预测实现。* 预测分析--本算法只适用于有明显线性趋势的数据 * 默认为一元二次曲线方程法 * * 本程序主要涉及有两个算法 * 1．用最小二乘原理找到线性方程组的系数和常数。 * 2．解线性方程组 * 本程序在解线性方程组中，由于考虑到收敛性问题未采用迭代法，而是采用Gauss-Jordan消去法来解决。-data prediction algorithm is mainly one yuan n equation forecast to achieve reunification.* Forecast and Analysis-- This algorithm applies only to clear linear trend data* default as a quadratic curve equation method** The procedure involves two main algorithm* 1. Using the principle of least squares linear equations to find the constants and coefficients.* 2. The solution of linear equations* The procedure for solving linear equations, due to convergence problems using iterative method, instead of using the Gauss-Jordan elimination method to solve.

仓储在企业的整个供应链中起着至关重要的作用，如果不能保证正确的进货和库存控制及发货，将会导致管理费用的增加，服务质量难以得到保证，从而影响企业的竞争力。传统简单、静态的仓储管理已无法保证企业各种资源的高效利用。如今的仓库作业和库存控制作业已十分复杂化多样化，仅靠人工记忆和手工录入，不但费时费力，而且容易出错，给企业带来巨大损失。

phpMySQLAutoBackup能自动备份mysql数据库，并将导出的数据库（数据与结构）压缩成gzip格式然后用email通知你。phpMySQLAutoBackup能够按设置每天/周定时备份，选择不同的表格来备份，当备份表格时,可以设置备份开始和结束的行数，以便让你能够有选择的备份一个巨大表格(数百万条数据)任一部分。 -phpMySQLAutoBackup can automatically backup mysql database, and export the database (data and structure) and then compressed into gzip format to inform you by email. phpMySQLAutoBackup able to set up a day/week timer backup, choose a different form to back up, when the back-up form, you can set the beginning and end of back-up the number of rows, so that you can choose to backup a large table (millions of data) any part of.
