The below are some of the sample questions that can impact the design of the database:
- Is it required to develop the database for all departments at once or whether it is required to design and implement the database for one particular department?
- What will the design approach required that could affect the process of designing?
- What type of development is required, one module at a time or integrated system approaches (Example: Billing, production, shipping and inventory)?
- What type of tracking system is required that is in terms of tracking the nuts and bolts through lot number, by shift, by production, by type or by department?
- What type of tracking system is required for the suppliers of each batch that is in terms raw materials used in the production of the nuts and bolts?
- Is it required to track the customer information regarding the receive summary of nuts and bolts based on batches?
- What type of reporting system is required that is what type of reporting requirements are required and who requires the distribution report details needs to be specified?

Draw an ER diagram of the following:
You are going to set up a database company that builds a product for art galleries. The core of this product is a database that captures all the information that galleries need to maintain. Galleries keep information about artists, their names (which are unique), birthplaces, age, and style of art. For each piece of artwork, we need to record its unique title, the year it was made, its type of art (e.g., painting, lithograph, sculpture, photograph), and its price. An artist may paint many pieces of artwork and a piece of artwork is done by one artist. Pieces of artwork are also classified into groups of various kinds (for example, portraits, works by Picasso, or works of the 19th century). A given piece may belong to more than one group. Each group is identified by a name that describes the group. Finally, galleries keep information about customers. For each customer, galleries keep that person’s unique name, address, total amount of dollars spent…
Specification
Suppose you are asked to design a club database system based on the _following
information. Each student has a unique student id, a name, and an email; each club
has a unique club id, a name, a contact telephone number, and has exactly
one student as its president. Each student can serve as a president in at most one of
the clubs, although he/she can be the members
several clubs. Clubs organize
activities and students can participate in any of them. Each activity is described by a
unique activity id, a place, a date, a time and those clubs that organize it. If an activity
is organized by more than one club, different clubs might contribute different
activity fees.

Use a word-processing, graphics, or spread-sheet program to draw an entity-relationship diagram showing the relationships among these entities.

And I'm aware of the hardware requirements. The concept of programming the rules and structure of a database is the area in which I am most confused. A database, in my mind, is a chart (or many charts) containing fields that are used to hold records. Then, of course, those records in one chart interweave with those in other charts, necessitating the creation of chart linkages. The concept of developing a framework for the data to fit into is where I get stuck. Are we creating metaphysical venues to store data, or are we just recording relationships between data saved on a variety of platforms?arrow_forward

They include the PARLIAMENT and the SENATE. A MINISTER in the PAKISTAN is either a Parliament Member or a Senator depending on to which body they are elected to. The database needs to keep track of each PAKISTAN CITY’s Name (e.g., ‘Lahore’, ‘Karachi’, ‘Multan’) and include the Region of the country to which the city belongs (whose domain is {‘Punjab’, ‘Sind’, ‘KPK’, ‘Baluchistan’}) and its population in the 170 million. Each MINISTER is described by his or her Name, plus the District represented, the Start_date when the parliament was first elected, and the political Party to which he or she belongs (whose domain is {‘PPP’, ‘PTI’, ‘PML(N)’, ‘PML(Q)’, ‘ANP’, ‘MQM’, ‘Independent’, ‘Other’}).

Each course is associated with multiple lessons. A lesson has a lesson number, a location, a date, a start-time, and an end-time. Lesson numbers are sequentially numbers, starting from 1, generated separately for each course. Each teacher teaches at least one course. Each student takes at least one course.

- I understand the intentions of a database, being to streamline the data record-keeping of any organizations. And I understand the hardware needed to do such. The area I find myself the most lost in is the idea of programming the rules and structure of a database. In my head a database is a chart (or multiple charts) with fields that is used to store records. And then those records stored in one chart intertwine with other charts of course so we need to have relationships between the charts. Where I get lost is in the thought of programming a structure for the data to fit in. Are we making metaphysical locations to store data or are we just writing relationshipds between data that is stored on a plethora of different options?arrow_forwardProblem: Your team of Data Analysts have been asked to create a database design for the Boeing X Aircraft Company (BAC), which has two HUD (heads-up display) products: TRX-5A and TRX-5B. The database must enable managers of BAC to track blueprints, parts, and software for each HUD, using the following business rules: For simplicity’s sake, you may assume that the TRX-5A unit is based on two engineering blueprints and that the TRX-5B unit is based on three engineering blueprints. You are free to make up your own blueprint names. All parts used in the TRX-5A and TRX-5B are classified as hardware. For simplicity’s sake, you may assume that the TRX-5A unit uses three parts and that the TRX-5B unit uses four parts. You are free to make up your own part names. BAC wants to keep track of all part price changes and the dates of those changes. BAC wants to keep track of all TRX-5A and TRX-5B software. For simplicity’s sake, you may assume that the TRX-5A unit uses two named software components…arrow_forwardYour Division Head's point of view is as follows: "Pictures are stored in a database, and the basic design/structure we chose includes some very sensitive driver information."

The company is organized into DEPARTMENTs. Each department has a name, number and an employee who manages the department. We keep track of the start date of the department manager. A department may have several locations. 2. Each department controls a number of PROJECTs. Each project has a name, a unique number, and a brief description. 3. We store each EMPLOYEE's social security number, address, salary, gender, and birthdate. a) Each employee works for one department but may work on several projects, which are not necessarily controlled by the same department. b) We keep track of the number of hours per week that an employee currently works on each project. c) We also keep track of the direct supervisor of each employee. 4. Each employee may have a number of DEPENDENTs. a) For each dependent, we keep track of their name, gender, birthdate, and relationship to the employee. We…arrow_forward
