物资管理是一般工业、商业企业生产管理还击中重要的一环，需要对物资基本信息管理、物资调配信息等进行完整的监控。物资入库首先需要登记物资的基本信息，包括物资的种类、名称、型号、单位等；然后登记入库信息，包括物资基本信息、入库地点、入库人、经办人、数量等；出库物资需要登记出库信息，包括物资基本信息、出库地点、出库人、经办人、数量等；根据物资的入库、出库过程的综合，得到各种物资的余额信息，方便进行后续工作。因此物资管理信息系统需要记录物资流通的全过程。-materials management is general industrial, commercial enterprise production management responded important aspect of a need for basic supplies information management, materials information for the deployment of a complete monitoring. The amount of material goods must first register the basic information, including the type of materials, name, type, units, etc.; Arsenal then registration information, including basic information materials, storage location, storage, handling, and so on; Out-up materials needed for registration information, including material basic information out of the hangar location, out of the hangar, handling, and so on; based on the amount of material in and out of the process of integration, access to the material balance information and faci

C#开发的订单程序(SQL Server2000数据库)-C# development orders procedures (SQL Server 2000 database)

由于源码是由网上收集的(原英文)，可能会有少许未能完善之处。但经过测试，大部分基本的运算还是可以的，当然包括常用的函数（三角函数、反三角函数、双曲三角函数、绝对值.......），甚至是一些复杂无比的表达式也能计算，如：ln e + rnd(2) + 3(2)4 * (log(tan (itan 1))) 等。值得一提的是，它还有函数绘图、数据统计和自定义常数等功能。另外，程序经过我汉化（仅在界面上），更易懂。 -As the source is collected by the Internet (former English), there may be a little failure to perfect. However, after testing, the majority of basic computing can, of course, including the commonly used functions (trigonometric functions,反三角函数, hyperbolic trigonometric functions, absolute value and even some .......), infinitely more complex expression can be calculated, such as: ln e+ rnd (2)+ 3 (2) 4* (log (tan (itan 1))) and so on. It is worth mentioning that, it also function mapping, data and custom constants and other functions. In addition, the procedures after I finished (only in the interface), more easy to understand.
