Acs Assignment 2, University of Winnipeg

ACS 1803 ASSIGNMENT 2 Due February 11, 2013 To be d iodine individually. 1) a) 8 A hospital ward wants to com giveerize its selective teaching about(predicate) long-sufferings and medications / acids prescribed for the unhurrieds. In your mind, comp ar this situation with the in-class example about students, courses and grades student is analogous unhurried, course is like medication and grade is dosage. Then, manipulation the quest fields of hospital entropy that are put into one file ( delay) patient No. , patient name, patient address, patient birth date medication name, medication dosage (this means how some(a) mesats or teaspoons of that medication the patient must take each day).Use the following info ? John smith Date of consanguinity Oct. 10. 1969 ring123 Dialysis mien. ethical drug Prilosec. iii tablets effortless Adavart . triplet tablets free-and-easy patient of ID 1849 ?

Jane vigour Date of Birth Aug. 01. 1949 mastermind725 O confront Ave. Prescription infliximab. Three tablets daily Diovan. Four tablets daily Gardasil. adept teaspoon daily Patient ID 1851 Show this in one table with all your data eternizes.Then explain fully why this would not be a good way of organizing data on dish antenna. b) 10 exchange the one table in the forward question to a comparative database design. Fill each table in your design with data from the previous question such that no information is lost. Show how your design satisfies the criteria for cosmos a relative database, and why it is better to store data on disk in this way rather than all in one table. c) 7 What is database management remains? What steps would the hospital ward pauperisation to take to prepare its data to be ready for producing meaningful return signal from the database man agement governance? ) 5 What are two main forms of product from a DBMS? Provide one example of each form of output using hospital data from your database in b). Hint Utilize the Input-Processing-Output position and focus on the ways data bum be produced i. e. subject versus Query. See Data Modeling Explanation from Lecture 4. 2 Notes for additional information. 2) 10 If a billet organization has its data stored on disk as a relative database which is managed by a database management system of rules such as access, why great power it want to go gain ground and confirm a management information system constructed, that would use this relational database as input?Why would just using door at a time not be enough for the organization? Explain fully with examples. ACS-1803-053 engagement 2 1. a. ) Patient NO.

As the table above, the uniform information such as No. , patient name, address, birth day, has been record more than once, which causes the waste of store space and costs more take time.However, with the increase in data, it might make some mistakes by multiple-display the some information. For instance, we have five patients named Jane Doe, and each of them has three kinds of medications. When we search the key haggling Jane Doe, we willing get 15 results with the same patient name, Jane Doe. It makes mistakes uncomplicated and takes more time when we have to find the only one information we hire among such a bunch of results. b. ) Patient Personal breeding Patient Patient NO.

Besides, a relational database allows tables to be linked. And the linkage reduces data redundancy and allows data to be unionised more logically. In a word, relational database is easier to control, more flexible, and more intuitive than approaches. c. ) The database management system (DBMS) a group of programs used as user interface between a database and application programs, or a database and the user. It is used to force and implement the right database system images that the database will support both business activities and goals.For the hospital ward, there are four basic steps need to take to prepare its data to be ready for producing meaningful output from a DBMS 1. Setting schemas. Installing and using a intumescent database involves telling the DBMS the logical and physical structure of the data and the relationships among the data for each user. 2. Establishing a data dictionary. In this case, the data dictionary should stockpile the following information patient No. , patient name, patient address, patient birth date medication name, medication dosage. . Storing and retrieving data. Establishing tables and input all the information, like 1849, John Smith, 123 Dialysis Way, Oct. 10. 1969, into them according to the data dictionary. 4. Manipulating data and generating reports. After a DBMS has been installed, users can use it to review reports and obtain important information. d. ) There are two main forms of output from a DBMS, which are research and report. The query is a database function that extracts and displays information from a database given selection parameters.Database users use Structured Query Language (SQL) to select and extract data from a database, and the SQL is the industry standard language for relational databases. The report is a digest of data from the database that is organized and produced in printed format or presented on screen. The report generator is a specialized program that us es SQL to retrieve and manipulate data (aggregate, transform, or group), and the reports are designed using standard templates or can be custom generated to meet informational needs. Query ExampleSelect patient ID, Medication Name from Medications Where Medications Name = Adavart Order By Patient ID 1849 Adavart Three tablets daily Report Example show a report of patients live on Olive Avenue. Patient No First Name pass away Name Street Patient Birth date 1851 Jane Doe 725 OliveAve. 1949-08-01 2. The access code is a database management system (DBMS), organizations use Access to implement database, after(prenominal) database designed. There are two main steps to use Access step one is setting up the database, the DBA needs to create the database, auspicate out tables and link them together.The second step is using the database through the DBMS, where we have to know the features to design and create queries and reports. We can also use Access as an information system developer, and use a customized information system for circumstantial purposes and needs. That is the reason why it might want to go kick upstairs and have a customized information system constructed, which would use this relational database as input. Using Access directly just only open a computer files in order to get or add information, it might not be enough for an organization.The customized information system is created according to processes and specific needs in order to improve the operational efficiency. The customized information system consists two parts up-front and controls. Up-front refers to its own menus, input screens, output (query) screens, and reports and, in the background, it will have a database with related tables, and programs that take the raw data from the database and shift it to the required queries and reports the system will also have controls, that is, mechanisms that try to ensure that the output is correct and that the data is safe from accidental or wei gh destruction.
