It the file such as the only evidence in of all kinds system, bill translates an user into file of EDI standard format, traffic, commerce, carry, the business data such as custom, carry electronic special railway line or Email mail, undertake with format of EDIFACT of ／ of international standard UN data is exchanged, the syntactic regulation that consolidates according to international undertakes handling to message, it is a kind of new business that handles work quickly through the computer.

它把用户各类系统中的单证、票据等文件翻译成EDI标准格式文件，将交通、贸易、运输、海关等业务数据，通过电子专线或Email邮件，以国际标准UN／EDIFACT格式进行数据交换，并按照国际统一的语法规则对报文进行处理，是一种通过计算机迅速处理事务的新业务。EDI具有快速、及时、廉价、安全、不受时空限制等优点，它降低了人工操作的错误率，提高办事效率减少纸张文件的消耗，改善了客户服务质量。

Electronic map of MapInfo is introduced into the environment of object oriented by the use of Map X 4.0 module. The operations such as dynamic add, delete and edit of objects can be done real-time dynamically by operators in the environment of object oriented on the present diagram of polder region. At the same time, the spatial-data and attribute-data of irrigation district are managed separately. The spatial-data is used by the file system, whereas, the attribute-data exist in the relevent database. The figures and database are related through the only ID number in order to realize two-way inquiry, so that, the polder region river system planning data are collected automatically. Moreover, this system make the great use of GIS advantage in storing and annalising data to automatically organize files needed in river network calculation , adopt one-dimensional unsteady flow model , so as to lay out height of river levee .

把GIS技术引入水系规划，通过MapX4.0组件把MapInfo电子地图调入面向对象编程环境，使操作人员能在面向对象环境中对圩区现状图进行实时动态操作，包括对操作对象的动态添加、动态删除、编辑等；同时，将空间数据和属性数据分开进行管理，空间数据用文件系统管理，属性数据采用数据库管理，通过建立唯一ID号进行数据联接，将图形与数据库进行关联，实现属性到图形或图形到属性的双向查询，从而实现了圩区水系规划部分数据的自动采集；另外，本系统充分利用GIS存储与分析数据的功能，自动生成河网水力计算所需的文件，采用一维非恒定流模型进行河网水力计算，为确定沟道堤顶高程提供依据。

By inputting Shp file this program can be used to build isolines. At the same time isoline data can be outputted and read by some GIS software which regard Shp file as one of input data format.

直接读取Shapefile数据文件，生成线格式的Shapefile文件，使生成的等值线图能用于其它基于Shapefile文件格式的GIS软件中。

Information is stored in mass storage systems in large units called files. A typical file may consist of a complete text document, a photograph, a program, or a collection of data about the employees in a company. The physical properties of mass storage devices dictate that these files be stored and retrieved in multiple byte units. For example, each sector on a magnetic disk must be manipulated as one continuous string of bits. A block of data conforming to the physical characteristics of a storage device is called a physical record. Thus , a file stored in mass storage will typically consist of many physical records.

在大容积存储系统中，信息是以称为文件的大的单位存储的，一个典型的文件可以是一个全文本的资料，一张照片或一组关于公司员工的数值，大容积存储系统的物理特性表明，这些个文件是按照许多字节为单位存储的检索的，例如，磁盘上每个扇区必需作为一个持续的二进制位串进行操作，符合存储系统物理特性的数值块称为物理记录，因此储存安放在大容积存储系统中的文件通常包罗许多物理记录。
