Once you understand the benefits associated with a relational database you decide to build a small database to help you track and analyze

I would have the fields set up as first name (EMP_FIRST), middle initital, (EMP_INITIAL), last name (EMP_LAST), area code (EMP_AREACODE), phone (EMP_PHONE).

2. using the data requirements and the business rules provided, develop a conceptual model (ERD), including attribute data types and required field lengths; and

This must be in your own words and not copied and pasted from the original source. Include the purpose of the database and the subject matter it covers. This may be four or five sentences; and

Understanding the business model of enterprise and identifying the entities of that model is the first step in setting up database. Requirements analysis includes tasks of determining the needs or conditions to meet. Requirement specification document will be generated at the end of this step.

Prior to designing my database, I will have a clear understanding of the data. This will allow me to determine the purpose of the database. Once all information is

Except where indicated, use MySQL Query Browser to perform each operation and print the results.

The information system’s requirements in the systems planning phase are based on a case summary, potential interview questions, and the systems analyst’s experience in systems planning. One must not only generate requirements based specifically on what users’ state they want or need. Analysts must also generate requirements based on insight into the overall organization and project goals.

The next step in the process is system analysis. This second stage involves gathering requirements, such as documenting the strengths and weaknesses of the current system, having discussions with the users to understand their roles and needs. This is an integral part of the life cycle as employees are the most important asset a company has. Baya, Gruman, & Mathaisel state, “information technology

The description of the requirement is very important in the process of acquiring an information system, stating of sections it intends to function, opportunities and problems it may arise during adoption stage (Bernroider, 2008). The description is as important

In order to obtain peer reviewed research articles related to the impact of the psychological contract on job satisfaction in community mental health care workers it is important to review research that has been completed in a variety of researchers and in different settings. The databases that were selected to locate peer reviewed articles for this paper where Academic Search Complete and ProQuest Psychology. Tutorials were available for each of these databases and ProQuest was used to learn how to navigate through the data base since it was not a familiar data base to this author.

Few companies today can exist without an IT department. The IT department contains many of the company’s technology experts. Almost all companies rely on computers to some degree whether it is an international conglomerate or a small startup company. Some companies are very dependent on computer systems while others use them only for accounting for payrolls and everyday computer tasks. Most organization, even the smallest company have people whose job is to make sure that the computer system is up and running or an emergency contact to call when the computer systems goes down. In the future, I want to take the head of a database administrator of an IT department whether the size of the company is small or enormous.

The database used should be open and industry standard to allow easy integration with other applications and easy movement of data in the future. The database

Databases allow us to easily store and retrieve data in a purely digital format. The strength of this is that large amounts of data can be stored and retrieved with minimal effort on the part of the user. Opposed to manually flipping through files, one can quickly pull up the requested data through a computer program. Many systems that were conventionally paper and file based have been converted to a digital format which are now stored in one or more databases.

The interview session has been done by include an open-ended and closed-ended question which are related to the implemented project. Next, sampling technique is executed by system analyst who does evaluation to the current system or prototype. These processes give feedback in evaluation form that filled after tested the system. Lastly, observation is performed by using questionnaire form. According to Burch (1992), the questionnaire is analyzed and transform into structured form that easy to understand. After all information has been collected, structuring of system requirement takes place. It focused on development process modeling which perform “graphically representing the process, or actions, that capture, manipulate, store, and distribute data between a system and environment” (Hoffer, George, & Valacich, 2012, p. 182). In this step, Data flow diagram (DFD) is structured by system analyst using special tools and techniques to create a decision table. According to Hoffer, George and Valacich (2012), decision table is a “diagram of process logic where the logic is reasonably complicated” (p. 200). This table is useful to help system analyst to make a decision toward the project. Then all information’s gained from this phase are documented in System Analysis Report (SAR) that acts as a guideline or reference to the future system development project (Burch, 1992).
