Data Model and Data Flow Diagram Assignment Essay

Data Model and Data Flow Diagram Assignment - Essay Example As the customer starts selecting products, the customer is given a "shopping cart". At the end, the customer can check out the shopping cart. At this time, he will be asked for personal information as well as login information for future purposes. The personal information includes the email, gender and date of birth in addition to the usual personal information needed for online shopping. He is also asked for credit card information (PresRX accepts only Master, Visa and American Express). Since PresRX also sells prescription drugs, if the "shopping cart" for the customer contains a product that is available only by prescription, the customer must provide the physician's information as well. This information will include the physician's name, address, specialty, phone number, email, fax number and hospital/clinic affiliation (we care about only the clinic that our customer goes to). (If the physician's info is not provided, we will contact the customer and obtain the info.) The custom er can also select the shipping method: we provide overnight, standard air and standard ground. For some of the drugs that are time and temperature sensitive, the customer will not be able to select the shipping method: the shipping method will automatically be chosen. The products will always be shipped to the person who orders them. If the customer wishes to use his insurance to make the purchase, we obtain the insurance company information as well as the insurance number and we will validate it by contacting the insurance company. Once the credit card is validated, we request validation from the insurance company on the prescription, physician on the prescription and validation of the physician from the hospital/clinic (to prevent fraudulent prescriptions). This is done via an automated email sent to the clinic as well as the physician. If emails are not made available, one of the employees will fax the request. This request will contain the drug requested, the quantity ordered, date it was ordered and the customer's name, address and phone number. The insurance company is called. We do this every time the person shops. The physician's office is given access to a physician's portal where his office can approve the prescription drug order. On approval, the drug is packed and shipped to the customer. The physician's portal is available where physicians can log in to not only approve the prescription request but also to renew the prescription for their patients. We also need to obtain supplies regularly. The reordering is based on need, triggered by low stocks. The system will have to reorder from the supplier via automatic ordering. As the products are shipped to our customers, the system updates the product quantity and as soon as the quantity goes to a pre-set "low" (different for each product), the system will immediately send an order to the product's supplier. Since we handle brand items, each product will have only one supplier. For each product we receive, our employees will update the product quantities in our system. The employees doing this will be the warehouse managers and we need to know who entered which batch of received shipments. Since prescription drugs

Teaching Reflection - Essay Example My work placement at *****, gave me an invaluable insights into the relevant approach to teaching chemistry. The experience was extremely helpful in understanding the various methods used by teachers in helping their students understand the subject with an in-depth comprehension of concepts. My two-week placement entailed working hand in hand with the chemistry teachers in the school. I was able to observe their methods of teaching the science and I assisted in a number of areas to enable myself be more acquainted with what dissemination of scientific knowledge to secondary school students is all about. In my first week of my work placement, I was able to take charge of some class activities, whereby I was assigned a duty of assisting students with difficulties in chemistry (Ellison 2008, p.46). My interactions with the teachers offered me an opportunity to learn about developing a lesson plan that is suitable for teaching science and chemistry in precision. The plan is an extremely important step, if the teacher wants to remain relevant in the classroom. Here, an instructor starts by identifying what is going to be covered in every particular lesson. Then the objectives of the lessons are determined, so that a teacher can identify the specific behaviours and capabilities that a student should exhibit after every lesson is covered (Sanderson 2002, p.23). Most of the teacher in the school used descriptive objectives. This provides a better platform for the educator to get great feedback on his/her teaching effectiveness, and students’ progress as well. Taking time to determine what the learners already know about the subject matter would enhance the overall success of completion of a lesson. Chemistry is relatively practical lessons, and having this in mind, teachers ensured that the necessary material and apparatus necessary to be used in a particular lesson are identified in the lesson plan in an attempt to accomplish the objectives described. These mat erials are highly useful in facilitating the learning process. Thus, as observed, a lesson plan increases the efficiency of teaching practice and the quality of the students’ learning time (Dorin 2002, p.29). Varieties of teaching approaches were also evident in the school learning processes. Here I actively participated in facilitating group discussions. These activities tend to generate interest in the topic under study and students are able to learn from friends. The teachers were also involved in helping out in explaining the concepts that were beyond the then understanding of the students. The teachers also had a variety of methods that they used to facilitate learning process. They give out assignments that required further reading and research on the subject matter. The main theme here was, â€Å"thinking further†. Learning partnership among student also seemed to develop a longer term learning culture among themselves (Gabel 2004, p.31). As observed, this appro ach helped weak students to learn continuously from their peers and consequently gaining much more understanding on chemistry. I also learnt that the teachers generally applied the three learning theories in identifying a suitable methods and media of teaching in the school. These include the cognitive, psychomotor, and affective domains. The psychomotor domain is generally skill based. Here the student tends to produce a product. It entails practical instructional levels that include imitation, practice, as well as habit. The psychomotor domain steep in a demonstration, delivery as well as the first level, imitation, which simply is a return of demonstrations that are under the control of the instructor. Additionally, the practice level is a proficiency building experience, which is
