1. Create a database named “Bookstore” and tables, using the following E-R diagram.E-R diagram is given in attached file.1You could create the database on AWS using RDS, or you could create your database on your local machine.2. Create a website for access your database, and include some functionalities, like:• insert records to each table, you may need to update other tables when you need to insert a record to a table.• query records from each table using different columns• delete records from each table, you might need to update other tables when you delete a record from a table.3. You could use any framework to develop your website, for example:• if you are familiar with Python, you could use Flask or Django• if you are familiar with javascript, you could use Node.js

While this weeks topic highlighted the uncertainty of Big Data, the author identified the following as areas for future research. Pick one of the following for your Research paper:Additional study must be performed on the interactions between each big data characteristic, as they do not exist separately but naturally interact in the real world.The scalability and efficacy of existing analytics techniques being applied to big data must be empirically examined.New techniques and algorithms must be developed in ML and NLP to handle the real-time needs for decisions made based on enormous amounts of data.More work is necessary on how to efficiently model uncertainty in ML and NLP, as well as how to represent uncertainty resulting from big data analytics.Since the CI algorithms are able to find an approximate solution within a reasonable time, they have been used to tackle ML problems and uncertainty challenges in data analytics and process in recent years.Your paper should meet these requirements:Be approximately five pages in length, not including the required cover page and reference page.Follow APA 7 guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.Support your answers with the readings from the course and at least two scholarly journal articles to support your positions, claims, and observations, in addition to your textbook.Be clearly and well-written, concise, and logical, using excellent grammar and style techniques.

Q1: Garage Database [40 points]We want to design a database for a local garage. For each customer, we want to record the (unique) name, the customer address, and the contact phone number. For each vehicle, we want to record the unique vehicle’s identification number (VIN), and the vehicle’s make, model and year. For each repair job we want to record the description of the job done (maximum 200 chars), the date, and the total dollar cost. A repair job may involve zero or more parts (like, e.g., “windshield wipers”, “battery”, etc.) For each part we want to record its (unique) part number, the part name and its cost. In addition, note that:• Each vehicle may have 1 or more repair jobs.• Each customer may be the primary owner of 1 or more vehicles.• Every vehicle has only one primary owner (we ignore co-owners).• No vehicle can have more than one repair job in any given day.Please answer the following questions:Q1.1. (10 points) Draw an ER diagram for this database. Make sure to indicate primary keys, cardinality constraints, weak entities (if any), and participation constraints. List any assumptions you make in the process.Q1.2. (10 points) Translate the ER diagram in Q1.1 into relational database tables (i.e. give the SQL DDL statements). Make sure that the translation captures key constraints (primary keys and foreign keys if applicable) and participation constraints in the ER diagram. Identify constraints, if any, that you are not able to capture.Q1.3. (20 points) Identify the functional dependencies that you expect should hold for the Garage Database domain. Use the dependencies to find keys and BCNF normal forms.

Restaurant Database [ 40 points]The student administrator of the Mini University wants to design a database for profiling students’ preferences for the nearby restaurants and the dishes. For example, the student Jack Smith likes the “rib eye steak” at the “TGI Fridays”, not the “rib eye steak” at the “Olive Garden”, while the student Nancy Graham likes the Italian spaghetti at “Zeppoli’s”.• Each student has his/her SSN, the name, and the department.• Each restaurant has its name, and the mailing address.• The name of a restaurant may not be unique, but the mailing address is unique.• Each dish has the name and the price.• The price of a dish might differ on different restaurants. For example, “rib eye steak” is $15 at “TGI Fridays”, but $20 at the “Olive Garden”.• The name of a dish is unique within a restaurant. Two restaurants may have the same dish name.• A dish is offered by at least one restaurant, and a restaurant offers at least a dish.Please answer the following questions:Q2.1. (10 points) Draw an ER diagram for this database. Make sure to indicate primary keys, cardinality constraints, weak entities (if any), and participation constraints. List any assumptions you make in the process.Q2.2. (10 points) Translate the ER diagram in Q2.1 into relational database tables (i.e. give the SQL DDL statements). Make sure that the translation captures key constraints (primary keys and foreign keys if applicable) and participation constraints in the ER diagram. Identify constraints, if any, that you are not able to capture.Q2.3. (20 points) Identify the functional dependencies that you expect should hold for the Restaurant Database domain. Use the dependencies to find keys and BCNF normal forms.

The Center for Project Management in San Ramon, California, examined 24 IT projects and compiled a list of ten dumb mistakes. The center then presented this list to 50 conference attendees and asked them to grade their organization on each mistake. The average grade was between a C+ and D. Here are the ten mistakes:1. Mistaking every half-baked idea for a viable project. 2. Overlooking stakeholders, forgetting the champions, and ignoring the nemesis. 3. Not assessing the project’s complexity. 4. Not developing a comprehensive project charter. 5. Not developing a comprehensive project plan. 6. Not designing a functional project organization. 7. Accepting or developing unrealistic or unachievable estimates. 8. Accepting status reports that contain mostly noise and not enough signal. 9. Looking back and not ahead. 10. Not following a robust project process architecture.Read the above list and find an example of a project for which this is the case. The project can be one that you have personal experience with or that you have read or heard about. Describe the example and state which of the mistakes was made with respect to the project. (Note that there may be more than one for a particular project.) If you choose a project in the news, provide a citation so that your classmates can read more about it. Minimum length of response is 100 words. Respond to at least two other student posts.

The ideal minimum level of physical protection should be the two- person team. This allows for the greatest flexibility and highest protection in the smallest package (McGovern, 2011). The level of protection that is warranted is mostly predicated on the value of the principal and the threat and risk assessment involved with the job at hand. The level of the threat should dictate the level of protection provided. Some examples could be always having a cctv on them. Every location they frequent needs to be monitored. If anything, suspicious comes up the security team and see it firsthand on the cctv. Portable cctv’s can be used on the road or if the client is out and about. We should also scope out the area around the principal’s office and/or residence and observing. It helps determine the level of concern that needs to be addressed. Security can follow our client home or to their usual spots just to assess if the level of protection needs to be changed or adjusted. Our local law enforcement may be asked to keep an eye on the residence. Private security could also be hired for the client. We also need to make sure they have an alarm system at home. So, if we are not there and something happens. The proper authorities can be alerted. These are just some ideas, as what we do for each client differs from the other. I think the special protection should stop when and if the client requests. Or we can set them up with a transitional security team to help after they are done with us.
