Pine valley furniture company database
Pine Valley Furniture Company is a hypothetical furniture manufacturer that has implemented a database to store and manage its data. This essay will describe the various types of data that the Pine Valley Furniture Company database may contain, the benefits of using a database to manage this data, and the potential challenges that the company may face in implementing and maintaining the database.
One of the types of data that the Pine Valley Furniture Company database may contain is customer data. This may include information such as customer names, addresses, phone numbers, and email addresses. By storing this data in a database, the company can easily access and retrieve customer information when needed, such as when processing orders or responding to customer inquiries.
In addition to customer data, the Pine Valley Furniture Company database may also contain data about the company's products. This may include information such as product names, descriptions, prices, and images. This data can be used to create marketing materials, such as product catalogs or website listings, and can also be used to track inventory levels and manage product availability.
Another type of data that may be stored in the Pine Valley Furniture Company database is financial data. This may include information about sales, expenses, and profits. By storing this data in a database, the company can easily track its financial performance and make informed business decisions.
There are several benefits to using a database to manage the data of a furniture company like Pine Valley Furniture. One of the main benefits is the ability to easily access and retrieve data when needed. With a well-designed database, the company can quickly retrieve the data it needs, whether it's a customer's phone number or the price of a particular product. This can help the company to be more efficient and responsive to the needs of its customers.
Another benefit of using a database is the ability to easily update and maintain data. If a customer's address or phone number changes, for example, the company can easily update this information in the database, ensuring that the company has the most current data available. Similarly, if a product's price changes or a new product is added to the company's lineup, this information can be easily updated in the database.
There may be some challenges that the Pine Valley Furniture Company may face in implementing and maintaining a database. One potential challenge is the initial cost of setting up the database. This may include the cost of purchasing database software, hiring a database administrator, and training employees on how to use the database.
Another challenge may be the ongoing maintenance of the database. The database must be regularly backed up to prevent data loss, and it may need to be updated or modified as the company's needs change. This may require the company to allocate resources towards database maintenance, which could be time-consuming and costly.
In conclusion, the Pine Valley Furniture Company database is a valuable tool that can help the company to store, manage, and access the data it needs to operate effectively. While there may be some initial costs and ongoing maintenance challenges associated with implementing and maintaining a database, the benefits of having a centralized, easily accessible repository of data are likely to outweigh these challenges.
Next, extension to the remaining business functions resulted in enterprise-wide management systems, or ERP systems. Databases are used to store, manipulate, and retrieve data in nearly every type of organization, including business, health care, education, government, and libraries. The logicalschema is the representation of data for a type of data management technology e. The conceptual schema represents the view of the data architect or data administrator. These databases do not follow the general database approach that we have described, and they are unlikely to provide the benefits described earlier. ENTITIES Customers and orders are objects about which a business maintains information.

In fact, a recent report by TheData Warehousing Institute TDWI estimated that data quality problems currently costU. Its purpose is to create an overall picture or explanation of organizational data, not the design for a particular database. EXCESSIVE PROGRAM MAINTENANCE The preceding factors all combined to create aheavy program maintenance load in organizations that relied on traditional fileprocessing systems. Using the final ERD, we were able to develop the schemas with primary and foreign keys identified. Data warehouses provide users with the opportunity to work with historical data to identify patterns and trends and answers to strategic business questions. Figure 1-9 shows an example of such a matrix. Finally, one change that has dramatically affected the database environment is the ascendance of the Internet, and the subsequent development of applications that are used by the masses.

Helen Jarvis, product managerfor home office furniture at Pine Valley Furniture Company, knows that competitionhas become fierce in this growing product line. Because a database is one part of an information system, this chapter also examines how the database development process fits into the overall information systems development process. No overall map, plan, or model guided application growth. The chapter emphasizes the need to coordinate database development with all the other activities in the development of a complete information system. Next, we consider the benefits, costs, and risks of using the database approach. This person is responsible for creating detailed project plans as well asstaffing and supervising the project team. All ERP systems are heavily dependent on databases to store the integrated data required by the ERP applications.

Personal Databases Personal databases are designed to support one user. Often security and integrity controls are minimalbecause the emphasis is on getting working prototype versions ready as quickly as possible. Who are our 10 largest customers, and what are their buying patterns? Inefficiencies, however, have to be weighed against violating the core principles behind sound database design. Pine Barrens Covering one-fifth of the area of New J. External schema This is the view or views of managers and other employees who are the database users. Each CUSTOMER Places any number of ORDERs.

NEW, SPECIALIZED PERSONNEL Frequently, organizations that adopt the database approach need to hire or train individuals to design and implement databases, provide database administration services, and manage a staff of new people. Thus, the metadata shown in Table 1-1 do not include any sample data from the Class Roster of Figure 1-1a. Metadata are data that describe the properties or characteristics of end-user data and the context of that data. A product line may group any number of products, but must group at least one product. Ideally, each primaryfact is recorded in only one place in the database.
The figure also shows the major data files associated with each application. Further, what CUSTOMER information is stored, how it is stored and how it is accessed is likely not closely tied to either of the two systems. LENGTHY DEVELOPMENT TIMES With traditional file processing systems, each new applicationrequires that the developer essentially start from scratch by designing new fileformats and descriptions and then writing the file access logic for each new program. Using this example, the chapter introduces tools for developing databases on personal computers and the process of extracting data from enterprise databases for use in stand-alone applications. For example, suppose the sales manager wants a consolidated view of customer contacts.

We describe the activities of database design in Chapters 4 and 5 and of implementation in Chapters 6 through 9. This figure includes annotations to indicateroughly which database development activities occur in each prototyping phase. In order to better understand the range of database applications, we divide them into three categories, based on the location of the client application and the database software itself: personal, twotier, and multitier databases. IMPROVED DATA QUALITY Concern with poor quality data is a common theme instrategic planning and database administration today. The conceptual schema represents the view of the data architect or data administrator. The repository contains definitions of data, whereas the database contains occurrences of data.
Textbooks and organizations use many variations on the life cycle and may identify anywhere from 3 to 20 different phases. ANALYSIS—CONCEPTUAL DATA MODELING During the Analysis phase of the SDLC,the analyst produces a detailed data model that identifies all the organizational datathat must be managed for this information system. Data formats may be inconsistent or data values may not agree or both. By adding a few additional data items and providing some structure, we recognize a class roster for a particular course. Thus, the relational model provides ease of access for nonprogrammers, overcoming one of the major objections to first-generation systems.
Data and database administrators Data administrators are persons who are responsible for the overall management of data resources in an organization. These issues are covered in more detail in Chapters 8 and 10. It is important to keep in mind that all these schemas are justdifferent ways of visualizing structure of the same database by different stakeholders. The physical schema describes how data are to be representedand stored in secondary storage using a particular DBMS e. For example, conceptual data modeling occurs in both the Planning and the Analysis phases. Aproject is a planned undertaking of relatedactivities to reach an objective that has a beginning and an end. To cope with these increasingly complex data, object-oriented databases considered third generation were introduced during the late 1980s Grimes, 1998.
