1) How many records does the file contain? How many fields are there per record? There are 7 records (21-5Z through 31-7P) and each record contains 5 fields (PROJECT_CODE through PROJECT_BID_PRICE). 2) What problem would you encounter if you wanted to produce a listing by city? How could you solve this problem by altering the file structure? There is not a field for city, only manager’s address. In order to get a listing by city, you would have to break up the address into address, city, state, zip, file format. You can do an internal string search, but it is difficult to write and takes longer to execute. 3) If you wanted to produce a listing of the file contents by last name, area code, city, state, or zip code, how would you …show more content…
6) Looking at the EMP_NAME and EMP_PHONE contents in Figure P1.5, what change(s) would you recommend? 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). 7) Identify the various data sources in the file you examined in Problem 5. Employee data (names and phone numbers), project data (project name), and job data (charge per hour and project hours). 8) Given your answer to Problem 7, what new files should you create to help eliminate the data redundancies found in the file shown in Figure P1.5? Project file should contain project characteristics (name, manager/coordinator, budget), employee file should contain employee information (name, phone number, address, employee number), job file should contain billing charges per hour for each job type , and a charge file should keep track of the number of hours by job type being billed for each employee who worked on the project. 9) Identify and discuss the serious data redundancy problems exhibited by the file structure shown in Figure P1.9. (This file is meant to be used as a teacher class assignment schedule. One of the many problems with data redundancy is likely occurrence of data inconsistencies-two different initials have been entered for the teacher Maria Cordoza.) There are multiple entries for every teacher. If any person
This chapter helps to define some elements that may represent a city. For example, when
UNIX systems use to use flat files for storing data. Word processors and spreadsheet software can create flat files. Health Care facilities might use this type of data file for posting employee phone lists.
Sequential file organizations access data sequentially from the beginning [1], i.e. to reach file 27, the 26 preceding files must be accessed first. They are much slower to access compared to random access [1]. Sequential files are stored on a sequential access device [2]. The records contained in sequential files are stored in a predetermined order [2], according to the value of a search key [1], and are stored one after the other [2] as they are inserted into the file. Records can only be accessed (read from and written to) sequentially (i.e. in the same order that they were entered) [3]. Sequential files are designed for efficient processing [1]). Records stored in sequential files cannot be deleted,
1. Geocoded data is used for analysis of address data in which address locations are displaced and patterns are recognized with this
You will need to place your initials next to the patient names that you call so other staff do not call the same person.
The companies in the city are exposed to a very tight competition and because of this can help manage your business well and submit bankruptcy of government
The first section requires input of owner’s name in last, first, and middle as prescribed format. Fill in the street address, city, state, and zip code in spaces provides. Write the name in the format as requested, street address, city, state, and zip code of co-owner if applicable.
The file is stored on eight cylinders of the disk. The highest key values on the eight cylinders, in order, are:
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.
It depends on the clinic and hospitals, some clinics are using EMR and the unit numbering, while others use serial-unit numbering. However, almost all hospitals implemented EHR and using only the unit numbering. The family numbering and serial numbering were used many years ago and now nobody uses
This case study is based on the integration of electronic medical records known as EMR. The integration process came from Dryden, New York and was tested by a small medical practice named Dryden Family Medicine. The practice has been known for its outstanding family based services given to their community. The implementation process of EMRs doesn’t come without risks, but with its outstanding paper based medical record keeping that continued to expand as the practice grew left the Dryden Family practice no other choice but to try out something new in hopes for a better outcome.
Personal privacy today is a controversial and complex topic, which is influenced by a number of factors. There is an integral role that databases play in this highly debated topic. The fact that many people now carry out their transactions electronically is another important factor. There is also pressure on personal privacy for increased national security around the world to combat terrorism. In addition, personal privacy is even threatened by commercial factors and the Internet.
25.) If the query “Seattle Plumbers” is entered, Google will use the location term that is part of the query
One common method is to search within a one-mile radius of the subject property, but an appraiser using this method would retrieve data from the high-income area. Another method is to search by zip codes, in this case 92404. The heavy blue line on the map in Figure 2 shows the resultant boundary. As we can see, searching by zip code also results in too broad of a search. Searching by block groups would provide much more detail, but this type of search is not available using data from typical real estate data services.
Cities are places which have huge amount of gathering of people, collection of economic activities and complex infrastructure for people which all together are supported by transport systems.
