6 2. Personal ID The personal identifier (personal ID) used in the public administration system stores several information. The structure of the personal ID depends on the date of birth. Its use and rules of formation are prescribed by law, which was amended in the following way on 1 January 1997 and on 1 January 2000: 1. The personal ID is an eleven-digit number. 2. The personal ID should be formed in the following way: a) the 1 st digit stands for the century of birth and the gender of the citizen in the following way: Date of birth between 1 January 1997 Date of birth after and 31 December December 1999 male female male female b) the 2 nd to 7 th digits contain the last two digits of the year, the month and the day of birth of the citizen; c) the 8 th to 10 th digits give the ordinal number of those born on the same day; d) the 11 th digit is a check digit calculated from the first 10 digits through mathematical methods. 3. The 11 th digit of the personal ID is calculated in the following way: each digit formed according to items 2. a)-c) is multiplied by a number, namely the 10 th digit by one, the 9 th digit by two and so on. The products should be added and the sum should be divided by eleven. The ordinal number according to item 2.c) may not be issued if the remainder of the division by eleven is equal to ten. Display the information content of personal IDs using a worksheet processing system. During the solution take the followings into consideration. Whenever possible, use a formula, function or reference to get a correct result even if the source data are modified. There are parts in the exercise that use the results from a previous question. If you could not solve an exercise part completely, use its solution as it is, or enter an arbitrary value and work on with this value. This way you can receive marks for this exercise part as well. 1. Open data file idsource.txt, which is tagged by tabs and is UTF-8 encoded, using a worksheet processor so that the first value appears in cell A1. Save the table as persid in the default format of the worksheet processor. 2. Change the name of the worksheet to Result and insert a new worksheet named Details. 3. On worksheet Details enter the heading into the first row according to the example. 4. On worksheet Details columns B:L should contain the digits of the personal IDs using functions that can be copied flawlessly in both vertical and horizontal direction. 5. Columns N:W should contain the products that correspond with the method of formation and column Y should contain their sum. (The products should be formed only from the first ten digits of the personal ID. For the solution use a formula that can be copied flawlessly both horizontally and vertically.) 6. In columns B:F of sheet Result the information that can be acquired from the personal ID should be displayed according to the example. (The numbers may include leading zeros, for example 12 and 012 are both correct.) gyakorlati vizsga / május 11.

7 7. In the cells of column G display Correct or Incorrect using the results of the calculation parts depending on whether the 11 th digit of the personal ID satisfies the rule of formation or not. 8. On worksheet Result format the data and the results of the calculation parts so that each number and text can be read clearly. Display the borders only for those cells that contain data. In columns A:G of sheet Result set the font formats and the alignments according to the example. As a hint a few functions that can be used for the solution of the exercise: Hungarian version English version Explanation =közép() =mid() Returns a given number of characters from the text starting from the given character position. =érték() =value() Converts a text representing a number into a number. =maradék() =mod() Returns the remainder when a number is divided by another number.

8 3. Kossuth Prize The highest state award in Hungary is the Kossuth Prize. The data of the winners between 1948 and 2008 are available in files person.txt, profession.txt and when.txt. 1. Create a new database named kossuth. Import the data tables into the database with name person, profession and when. The text files are UTF-8 encoded, tagged by tabs and their first lines contain the field names. 2. After importing set the suitable data formats and keys. Tables: person (persid, persname) persid The identifier of the awarded person (or group) (number), this is the key persname The name of the winner (text) profession (id, persid, profname) id The identifier of the records in the table (number), this is the key persid The identifier of the awarded person (number) profname The profession of the awarded person (text) when (identifier, persid, ayear) identifier The identifier of the award (number), this is the key persid The identifier of the awarded person (number) ayear The year of awarding (number) Create the solution of the following exercises. In the queries pay attention to display only the requested values and no other data. Save your solutions with the names given in brackets. 3. Using a query, list the name of the awarded persons who received Kossuth Prize in 1990 in alphabetical order. Display only the names. (3ninety) 4. Using a query, list the name, occupation and year of award of those whose profession contains the word engineer. (4engineer) 5. Using a query, give the names of those who received Kossuth Prize more than twice and the number of awards for each of them. (5morethantwice) 6. Using a query, determine the year when the most Prizes were awarded and the number of awarded persons in that year. (6maxprizes) 7. Using a query, give the name and the year of award of those whose occupation is the same as Varga Imre s. Do not display Varga Imre s name in the list. (7vargaimre) gyakorlati vizsga / május 11.

9 8. Using a query, list the occupations of the people who received the Prize in 1948 and later no other person with the same occupation received the Prize. In the list display each occupation only once. (8ceased) 9. The naming of professions changed during the years. In order to have unified namings, change each occurrence of the profession actor into stage actor. (9actor) 10. Create a report about the name of poets grouped by the year of award. Next to the years the names should appear in alphabetical order. The report heading should contain the title Kossuth Prize winning Hungarian poets. You can create an auxiliary query or temporary table for the solution. (10poets) Example: 30 marks gyakorlati vizsga / május 11.

10 4. Plots In Streamville the area at the end of the village that is yet unbuilt on is divided into two parts by the Stream Bits. The municipality decided to create residential area Brave Future by forming building plots. After the building two streets will be created in a rectangular area: Prosperity Row and Fortune Row. The inhabitants of the two rows are foot-to-foot neighbours, but their plots are separated from each other by the Stream Bits. The two streets are parallel, the distance between the street fronts is 80 metres. On each row the same number of rectangular plots were designated, at most 30 plots per row. On Prosperity Row only odd house numbers, on Fortune Row only even house numbers were issued (starting from 1 and 2, without any omissions). The width of a plot is at most 40 metres. At the ends of the streets the two banks of the stream are connected by bridges. Upon designating the plots the path of the water course was taken into account. A registry of the designated plots has been created, it can be found in file plots.txt. The first line of the file contains the number of plots to be sold, the following lines contain the data of the plots one by one. The first data is the house number, the second is the width of the plot, and the third is the length, which is the dimension perpendicular to width. In the case of Prosperity Row every data is available, but in the case of Fortune Row there are zeros in the place of the length data. There is exactly one space between the data. Create a program named plots, which solves the following exercises. Before displaying the result of the exercise parts requiring output on the screen display the number of the exercise on the screen. (E.g. Exercise 3:) 1. Read the data from file plots.txt and solve the following exercises using them. If you cannot read the file, then enter the data of plots no. 1, 3, 5, 7 and 9 Prosperity Row and gyakorlati vizsga / május 11.

11 2, 4, 6, 8 and 10 Fortune Row from the file into the program and solve the exercises using these data. 2. How many metres should one walk to walk round the two streets? Display the calculated distance on the screen. 3. The local authority prescribes that in the case of plots whose width is 20 metres or less complete street front building is required. Determine and display on the screen the number of plots affected by this regulation on Fortune Row. 4. How many houses are there between the plots with the largest and smallest area on Prosperity Row? Display on the screen the number of plots between the two plots, the house numbers and the corresponding areas of the largest and the smallest plots. 5. The local authority will impose a tax on the plots. The tax is calculated in Pinny-pennies. In the case of plots with area 700 square metres or less the tax is 51 Pinny-pennies per square metre, in the case of plots larger than this it is 51 Pinny-pennies per square metre for the first 700 square metres, above 700 square metres to 1000 square metres it is 39 Pinny-penny per square metre. For the part above 1000 square metres the tax is not calculated per square metre, it is a flat sum of 200 Pinny-pennies. The owners of plots whose width is 15 m or less or whose length is 25 m or less receive a 20% tax allowance. When determining the tax, it should be rounded to 100 Pinny-pennies (e.g. in the case of 6238 it is 6200, in the case of 6586 it is 6600). Determine the tax revenue of the local authority from Prosperity Row. 6. Which are the last 3 plots on Fortune Row? Display on the screen the house numbers and the distance of the plots from the head of Fortune Row according to house numbers in decreasing order. 7. Determine the length of the plots on Fortune Row. Take into consideration that the minimum distance between the borders of the opposite plots towards the stream is 10 metres measured in the direction perpendicular to the street front. The plots are considered to be opposite each other even if only some parts of their borders lie on the same line. (For example the plots opposite to plot number 10 are only plots number 9 and 11.) In your calculation designate the largest plots that satisfy this condition. Write the data of Fortune Row into file fortunerow.csv. Each line should contain a house number, a corresponding width and a length. The data should be separated from each other by exactly one semicolon. 45 marks Sources: 1.
