Entity Relationship Diagram
When developing a relational database understanding the logical flow of information and proper planning will improve the probability of the database functioning the way it is intended and producing the desired results. In determining the proper structure of a relational database for a video rental store one must consider what information is stored, the process for renting videos and information on the videos maintained in inventory. Customer, Videos and Video Types are the entity classes that will be discussed and Customer Order is the intersection relation needed to explain the complete process as seen on the Entity Relationship Diagram below.
Customer
Maintaining detailed customer information is a critical function of a video rental store’s relational database. The primary key of the Customer entity class could be a field named Customer ID Number that is a unique number automatically generated when a new customer is entered. The video store could also choose to use a unique number identifying the customer such as driver’s license number, phone nu...
Huffman Trucking has recently hired a consultant company, Smith Systems Consulting, to design a database that will enable Huffman Trucking to better organize and track the truck maintenance for their fleet. Smith Systems Consulting has done an analysis of Huffman Trucking to develop a basic plan for integrating information into a database. Entities and attributes have been defined by Smith Systems, but the relationships and tables of the database still need to be defined.
The relational model consist of a relational structure, a set of integrity rules, and data manipulation operations. The relational structure is based on the representation of data in the form of tables. A table contains rows and columns, with each row representing an individual record, and each column representing a field for each record. Tables are related via indirect indexes of primary and foreign keys. The operations that are performed on these tables in order to store, manipulate and access this data include union, intersection, join, division, restriction, projection, assignment, difference, and product.
As defined by Kroenke Database is an integrated, self-describing collection of related data. Data is stored in a uniform way, typically all in one place- for example, a single physical computer. A database maintains a description of the data it contains and the data has some relationship to other data in the databa...
According to the task assigned to me, I have visited one of my favorite food court (i.e) TACO BELL. As a matter of fact each and every organization has a unique data requirements in this regard, this particular food court has its own requirement for data. The requirement may be seen at different levels. The first level of TACO Bell is Hiring manager. The hiring manager requires the data of the employee who work at Taco bell. On the next level will be a manager who looks after the inventory. Inventory management requires a database which works efficiently. So, at this level the use of the database is must. At the next level the data requirement of the cashier is different from others. The next level of data requirement is for the drive-away customers.
Determine how results are to be presented and shared. These steps can help you to create a database effectively.
The information can be made into categories which can be outputted to make choices for the future of the company. Information will be kept in the database and the database will contain tools to help process the information in multiple ways.
Organizations in today’s world need to adapt and overcome many obstacles that are predictable as well as unpredictable. Max Weber outlines the five basic principles of bureaucracy which are as follows: The Division of Labor, Hierarchy of Authority, Written Rules and Regulations, Impersonality Principal, and Technical Qualifications. These basic principals were designed to maximize productivity and assert authority over subordinates in the workforce. (Weber, 1968) In present day the basic principles of Weber’s bureaucratic design are still visible in just about every organization. The only variable is to what extent they are applied.
From the scenario described above, I have determined that the following main entities are the most appropriate for a relational database: cemeteries, burial plots, burial records, monuments, buildings, and inscriptions. Each main entity and its significant attributes will be described below; however, a full list of attributes can be found in the appendix.
The tools of data warehousing, Data Mining and customer relationship management (CRM) have enhanced businesses’ ability to create and build relationships with customers.

Normalization permits us to design our relational database tables so that they "(1) contain all the data necessary for the purposes that the database is to serve, (2) have as little redundancy as possible, (3) accommodate multiple values for types of data that require them, (4) permit efficient updates of the data in the database, and (5) avoid the danger of losing data unknowingly (Wyllys, R. E., 2002).".
And in order to know the customer, the company must collect information and store it in a database from which to conduct database marketing. A customer database is “an organized collection of comprehensive information about individual customers or prospects that is current, accessible, and actionable for lead generation, sale of a product or service, or maintenance of customer relationships. Database marketing is the process of building, maintaining, and using customer databases and other databases (products, suppliers, resellers) to contact, transact, and build customer relationships” (Kotler – Keller, 143). The institution has to notice at the same time that not all customers want a relationship with the organization. When it works, a data warehouse yields more than it costs, but the data must be in good condition, and the discovered relationships must be valid and acceptable to consumers (Kotler – Keller, p.
One important component needed for a cohesive work environment is relationships. Relationships help keep an organization together, and also provide a healthy and comfortable environment for the employees. Relationships bring personal cohesiveness, and personal support within an organization. There are different components that contribute to healthy relationships. They include the flow of communication, methods used to communicate, the way members communicate, the way conflict is handled, and the support and openness of the members.
Relationships: It represents the connection between data objects. For example the relationship between shopkeeper and a
In this paper I have analyzed the past and present condition of Blockbuster. Given the right circumstances and execution, Blockbuster can once again return to the video rental powerhouse status they enjoyed throughout the 1990s.
