WinRDBI Educational Tool

WinRDBI is an educational tool that takes advantage of the connection between logic programming and databases to provide an evaluator for relational query languages. The user interface is implemented in Java TM Swing and the database and query languages are implemented in Amzi! Prolog. The tool utilizes a common data definition facility and recognizes the following query languages: relational algebra,

q

domain relational calculus,

q

tuple relational calculus, and

q

SQL.

Using WinRDBI on campus

Installing your own copy of WinRDBI Before downloading and installing WinRDBI, you

must have the appropriate version (1.3) of the Java

Runtime Environment (JRE) installed on your

machine.r You must complete the registration form and

acknowledge the license agreement to download a copy of WinRDBI.

22 August 2000: WinRDBI 2.0.5.130

r FAQs

What versions of the JRE can be used with WinRDBI?

WinRDBI 2.0.5.130 is designed for use with JRE 1.3.

Note that the install program for WinRDBI assumes that the JRE is

installed first.

r Can I have multiple JREs installed on my machine at the same time?

Yes. Obviously, each JRE is in its own directory.

You can edit the shortcut for WinRDBI to reference the appropriate JRE.

r How can I edit the target of the WinRDBI shortcut?

The answer here is described in the context of a Windows NT machine.

Locate the shortcut associated with the WinRDBI program in the following

path:

C:/Winnt/Profiles/All Users/Start Menu/Programs/WinRDBI

Highlight the WinRDBI executable file.

Open its Properties by choosing Properties off of the File menu or the

right-mouse click menu.

Choose the Shortcut Tab.

The source of the target is displayed in a small one-line text window.

You will probably need to scroll in the target window to see its entire

contents.

r What should the target of the WinRDBI shortcut look like?

DRIVE:\JREDIR\bin\javaw.exe -cp

"DRIVE:\WinRDBIDIR;DRIVE:\WinRDBIDIR\WINRDBI.jar;"WinRDBI

where

DRIVE represents a drive specification

JREDIR represents the path to the JRE that you want WinRDBI to

use

WinRDBIDIR represents a path to where you installed WinRBDI

(e.g. Program Files\WinRDBI)

r What are the differences between WinRDBI 2.0.2 and the latest

version 2.0.5.130?

WinRDBI 2.0.5.130 is the first version of WinRDBI on the Java 2

Platform, which required a rewrite of the printing capabilities. A minor

r

syntax change was incorporated in the SQL recognized by WinRDBI.

WinRDBI recognizes SQL-89, since it was originally written in 1990. At

that time, the "except" operator was not part of the standard. However,

WinRDBI did incorporate a "minus" operator for SQL, which has been

changed to "except" in version 2.0.5.130.

What naming scheme is being used for the versions of WinRDBI?

r

The naming scheme for the versions of WinRDBI now includes a fourth

component to document the version of the Java Runtime Environment with

which WinRDBI has been designed and tested.

WinRDBI User Interface

WinRDBI User Interface

The WinRDBI user interface is implemented in Java TM Swing. WinRBDI 2.0 allows you to have multiple query panes open at the same time (a query pane is limited to one language: alg, drc, trc, sql) operating on one underlying database (rdb).

History of WinRDBI

History of WinRDBI

The original version of the educational tool, called RDBI, was implemented in Quintus Prolog and had only a command line interface. The following paper describes the motivation for RDBI and the syntax of the relational query languages recognized by the tool:

An Educational Tool for Formal Relational Database Query Languages

Suzanne W. Dietrich

Computer Science Education, Vol. 4, pp.157-184, 1993

To increase the availability of the educational tool and to provide a graphical user interface, a windows-based version, WinRDBI, was made available in Fall 1996. The following paper describes the features of WinRDBI 1.0 and provides nontrivial examples, illustrating how to write queries in the formal languages to support (a limited form of) counting and minimum/maximum queries: WinRDBI: A Windows-based Relational Database Educational Tool

Suzanne W. Dietrich, Eric Eckert and Kevin Piscator

Proceedings of the 28th ACM SIGCSE Technical Symposium on Computer Science Education, San Jose, California, February 27 - March 1, 1997, pp. 126-130

Unfortunately, there were several limitations in the design of the graphical user interface for WinRDBI 1.0 that motivated a new version of the tool. For example, WinRDBI 1.0 allowed only one query in one language to be specified at any time. WinRBDI 2.0 is a redesign and rewrite of the graphical user interface, using the capabilities provided by Java Swing. WinRBDI 2.0 allows you to have multiple query files open at the same time operating on one underlying database. Since all versions of the educational tool recognize the same syntax for the four query languages, the publications on the previous versions of the tool provide useful examples.

We expect future releases of WinRDBI based on changes to the Java Foundation Classes (JFC). We also hope to incorporate the checking of key constraints and the inclusion of referential integrity in the future.

机械加工中的刀具管理系统

机械加工中的刀具管理系统 随着加工系统的高速化、无人化及智能化发展,为了提高加工产品的品质,刀具管理的必要性尤为重要。因此,各企业为了提高生产效率,减少成本,都竞相引入刀具管理系统或建立刀具数据库。 1 刀具管理系统 机械加工中刀具管理系统是对N C 设备所需的刀具(铣刀和板料等1的基本信息、在库及购买的管理。 其主要职能有:1 ) 刀具管理:一般N C 用刀具的入库、检收、补充及报废管理; 2 ) S ( 自动化)刀具管理:对FM s 设备所需的刀柄和主轴管理; 3 ) 库房/购买管理:刀具的异体、预算、购买、订货及来历等的管理。 2 刀具室 刀具室的建立,不单单是作为一个库房来存在,它要完成的任务在制作过程中应该起到很大的作用,工作做的如何直接影响到产品质量,生产周期以及加工成本。 刀具室要记录各个设备的月消耗,通过对比分析来确定刀具使用情况,以便于更好的做出成本分析。 刀具室除了基础的刀具配送外,还应承担其他的任务。 1 ) 一般信息——刀具编号、材质、规格、刀具长度、直径及形状等。刀具室应该对刀具进行统一编号,以便于日后管理,并将刀具相关信息录入电脑记录,例如:F 1 2 —1 ( 编号为“l ”的直径中1 2 m l T l 平刀) ;B 1 0 —2 ( 编号为“2 ”的直径①1 0 m m球刀) 。当然可根据适合自己习惯的方法进行编号,录入刀具的一些基本参数, 以方便库管员根据加工程序单所示的的参数找到相应的刀具。 2 ) 加工信息——刀具寿命、刀具磨损量及切削条件。库管员根据现场反馈情况和日常统计明确刀具的使用寿命,以此来确定刀具的更换周期,及时地更新刀具磨损量,根据实际加工情况合理的配备合适的刀具,切勿大材小用。 3 ) 库房分析——刀具选取、品质水准、刀具修理及研磨、特殊刀具制作、供应商考核、 月消耗及设备考核。刀具管理可以说是~个很复杂的工作,不单单是把刀具送到现场,进行账目统计,以及刀具维修这么简单。在此过程中还要根据本部门所处的水准和加工类型来合理选用刀具。例如:对于大型汽车覆盖件,在做精加工时要使用品质有保证的机床 和刀具。我们公司是采用日本东芝高速龙门铣配黛杰高精度球刀来完成作业,若是做E 类 件就不必使用这类设备和刀具,国产刀具完全能够满足精度和面品需要。 选用刀具的时候,是用价高的还是价低的,要考虑刀具的性价比,例如,在建厂初期,

The country is situated mostly in central North America, where its forty-eight contiguous states and Washington, D.C., the capital district, lie between the Pacific and Atlantic Oceans, bordered by Canada to the north and Mexico to the south. The state of Alaska is in the northwest of the continent, with Canada to the east and Russia to the west across the Bering Strait. The state of Hawaii is an archipelago in the mid-Pacific. The country also possesses several territories in the Caribbean and Pacific. At 3.79 million square miles and with over 310 million people, the United States is the third or fourth largest country by total area. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The

基于数据库的刀具管理系统的设计与实现

基于数据库的刀具管理系统的设计与实现 来源:数控机床网作者:数控车床栏目:行业动态 本文通过需求分析、数据库设计和实现,提出了快速刀具查询和数据库管理系统,从而使刀具适应了数控机床高速、高效和自动化程 度高的特点,提高了刀具利用率以及数控加工的灵活性与效率,最终降低了新产品的开发成本,缩短了试制周期。 一、前言 随着人们对机械加工精度、效率以及特殊工件加工要求的提高,数控车间和加工中心已广泛应用于现代化大中型企业。在加工中心中 ,刀具管理是一项重要任务,它不仅为智能制造技术系统和PDM/ERP系统提供有效的技术支持,而且可为制造业进行网络化的虚拟制 造技术研究与开发奠定技术基础,是关系到加工产品的技术先进性、质量可靠性、供货周期、制造成本的关键环节。 作为加工中心工作中不可缺少的步骤,如何有效地组织刀具是影响加工中心乃至柔性制造系统效率的一个重要因素,现有的问题主要 是以下几个方面:如何组织刀具使刀具的存取更方便;如何调度刀具使刀具交换次数最少;如何选配刀具使刀具准备时间最短、利用 率最高。总之,研究刀具资源的管理就是用最小的刀具资源来达到生产要求,尽可能减少对刀具资源的占有。 经过大量调研和分析,该系统以VC++为开发工具,以Microsoft SQL Server 2000为后台数据库建立。 二、数据库设计 车间刀具的数据库管理系统,必须能满足不同用户的需要和要求,这里只详细说明设计过程中的概念结构设计和安全性设计。 1.概念结构设计 该数据库是一套高端数控程序管理系统,可以对程序的编辑者、刀具清单进行管理,还可以对数控程序的各种信息,如程序号、图号 、零件号、机床、用户信息等进行管理,下面是创建与数据库相关部分的实体关系图(ERD),如图1所示。 图1 DNC数据库总体E-R图 2.安全性设计 用户只能用账号登陆到应用软件,通过应用软件访问数据库,而没有其他途径操作数据库。对用户账号的密码进行加密处理,确保在 任何地方都不会出现密码的明文。除非是数据库管理员才能看到,因为他拥有应用软件的所有权限。 确定每个角色对数据库表的操作权限,在应用时再为用户分配角色。角色的权限如表1所示。 表1 角色权限表 三、后台数据库的实现 以VC++开发工具,运用VC++的数据库接口技术、Microsoft SQL Server2000为后台数据库进行dncdb数据库的设计,其具体设计过 程包括建立数据库、建立表、建立关系、实现数据完整性等几个步骤,下面分别介绍。 1.建立数据库
