In many organizations, database development from the beginning of enterprise data modeling, data modeling enterprises determine the scope of the database and the general content. This step usually occurs in an organization's information system planning process, it aims to help organizations create an overall data description or explanation, and not the design of a specific database. A specific database for one or more information systems provide data and the corporate data model (which may involve a number of databases) described by the organization maintaining the scope of the data. Data modeling in the enterprise, you review of the current system, the need to support analysis of the nature of the business areas, the need for further description of the abstract data, and planning one or more database development project. Figure 1 shows Pine Valley furniture company's enterprise data model of a part.
1.1 Information System Architecture
As shown in figure 1, senior data model is only general information system architecture (ISA) or a part of an organization's information system blueprint. In the information system planning, you can build an enterprise data model as a whole information system architecture part. According to Zachman (1987), Sowa and Zachman (1992) views of an information system architecture consists of the following six key components:
Data (Figure 1 shows, but there are other methods that).
Manipulation of data processing (of a data flow diagram can be used, with the object model methods, or other symbols that).
Networks, which organizations and in organizations with its main transmission of data between business partners (it can connect through the network topology map and to demonstrate).
People who deal with the implementation of data and information and is the source and receiver (in the process model for the data shows that the sender and the receiver).
Implementation of the events and time points (they can use state transition diagram and other means.)
The reasons for the incident and data processing rules (often in the form of text display, but there are also a number of charts for the planning tools such as decision tables).
在許多組織中,數(shù)據(jù)庫(kù)開(kāi)發(fā)是從企業(yè)數(shù)據(jù)建模開(kāi)始的,企業(yè)數(shù)據(jù)建模確定了組織數(shù)據(jù)庫(kù)的范圍和一般內(nèi)容。這一步驟通常發(fā)生在一個(gè)組織進(jìn)行信息系統(tǒng)規(guī)劃的過(guò)程中,它的目的是為組織數(shù)據(jù)創(chuàng)建一個(gè)整體的描述或解釋,而不是設(shè)計(jì)一個(gè)特定的數(shù)據(jù)庫(kù)。一個(gè)特定的數(shù)據(jù)庫(kù)為一個(gè)或多個(gè)信息系統(tǒng)提供數(shù)據(jù),而企業(yè)數(shù)據(jù)模型(可能包含許多數(shù)據(jù)庫(kù))描述了由組織維護(hù)的數(shù)據(jù)的范圍。在企業(yè)數(shù)據(jù)建模時(shí),你審查當(dāng)前的系統(tǒng),分析需要支持的業(yè)務(wù)領(lǐng)域的本質(zhì),描述需要進(jìn)一步抽象的數(shù)據(jù),并且規(guī)劃一個(gè)或多個(gè)數(shù)據(jù)庫(kù)開(kāi)發(fā)項(xiàng)目。圖1顯示松谷家具公司的企業(yè)數(shù)據(jù)模型的一個(gè)部分。
1.1 信息系統(tǒng)體系結(jié)構(gòu)
如圖1所示,高級(jí)的數(shù)據(jù)模型僅僅是總體信息系統(tǒng)體系結(jié)構(gòu)(ISA)一個(gè)部分或一個(gè)組織信息系統(tǒng)的藍(lán)圖。在信息系統(tǒng)規(guī)劃期間,你可以建立一個(gè)企業(yè)數(shù)據(jù)模型作為整個(gè)信息系統(tǒng)體系結(jié)構(gòu)的一部分。根據(jù)Zachman(1987)、Sowa和Zachman(1992)的觀點(diǎn),一個(gè)信息系統(tǒng)體系結(jié)構(gòu)由以下6個(gè)關(guān)鍵部分組成:
數(shù)據(jù)(如圖1所示,但是也有其他的表示方法)。
操縱數(shù)據(jù)的處理(著系可以用數(shù)據(jù)流圖、帶方法的對(duì)象模型或者其他符號(hào)表示)。
網(wǎng)絡(luò),它在組織內(nèi)并在組織與它的主要業(yè)務(wù)伙伴之間傳輸數(shù)據(jù)(它可以通過(guò)網(wǎng)絡(luò)連接和拓?fù)鋱D來(lái)顯示)。
人,人執(zhí)行處理并且是數(shù)據(jù)和信息的來(lái)源和接收者(人在過(guò)程模型中顯示為數(shù)據(jù)的發(fā)送者和接收者)。
執(zhí)行過(guò)程的事件和時(shí)間點(diǎn)(它們可以用狀態(tài)轉(zhuǎn)換圖和其他的方式來(lái)顯示)。
事件的原因和數(shù)據(jù)處理的規(guī)則(經(jīng)常以文本形式顯示,但是也存在一些用于規(guī)劃的圖表工具,如決策表)。
