Important information Devices allowed for the exam: computer assigned to the candidate, paper, pen, pencil, ruler, sealed notepaper.

You can take notes on the internal sides of the exercise sheet and on the notepaper, these should be submitted at the end of the exam but their content will not be evaluated.

The exercises can be solved in any order.

Please pay attention to frequent saving (every 10 minutes); it is recommended that you save your work every time you start a new exercise.

You should save your exam work in the exam directory that corresponds to your name. Check that this directory is accessible; if it is not accessible, notify the supervising teacher at the beginning of the exam.

Save your works in the exam directory and at the end of the exam check that every solution is in the given directory because only those solutions can be evaluated. Check that the files to be submitted are readable because files that cannot be opened cannot be evaluated.

If you solve the database management exercise with LibreOffice Base, then you should submit the SQL commands describing update queries either as part of the LibreOffice Base database file or as a separate text file. If you submit them as a text file, the name of the text file should refer to its contents clearly (e.g. SQL_commands.txt) and the required query name should be displayed next to the command in the file.

If you use a MySQL database engine, the data of the database should also be saved in a so-called “dump” file.

The source files can be found in the exam directory.

It is suggested that you read through the exercises first then solve the individual exercise parts one by one.

If your computer has technical problems, indicate it to the supervising teacher. The fact of indication and the observed problem will be recorded. The lost time will be added to the duration of the exam. If the problem is not of computer nature, the correcting teacher should take the description of the case in the record into consideration. (The system administrator cannot help the candidate with the solution of the exercises.)

At the end of the exam you should indicate the number and name of files created and submitted by you and located in the exam directory and its subdirectories on the first page of the exam document. When finishing the exam, do not leave the room until you have done so and have shown it to the supervising teacher.

2. Pythagoras Little is known about Pythagoras’ life, which is surrounded by legends. His mathematical

achievements mix with the achievements of his students, the Pythagoreans. The theorem bearing his name, which is taught in primary school already, had been known well before Pythagoras, but one of the proofs of the theorem is supposed to be his work.

Create a presentation about Pythagoras and his followers. You can find the text of the presentation in text file pyttext.txt, which is UTF-8 encoded. The pictures required for the presentation are given in the following table.

Picture on the 1st slide

Picture on the 2nd slide

Picture on the 3rd slide

Pictures on the 4th slide

pyt1.jpg pyt2.jpg pyt3.jpg music.jpg number.png geo.jpg

1. Create a six-slide presentation based on the example and the description. Save your work as pythagoras in the default format of the presentation program.

2. Perform the following settings on the slides: a. The background of the slides is a colour transition from black in the top left

corner to dark red, RGB code (150, 0, 0) in the bottom right corner. b. Use font type Arial (Nimbus Sans) on the slides and – where the exercise does

not specify else – font size of 53 points for the title and 31 points for the text of the slides.

c. The font colour of the text is white, the text of the titles is aligned left – with the exception of the first slide – and the font style is bold.

3. Type in the text of the slides according to the example or copy it from file pyttext.txt. 4. On the first slide, format the title at the top of the slide, in the top right corner using font

size of 70 points and bold font style. Insert picture pyt1.jpg into the background of the slide. (The picture may be distorted depending on the side ratio of the slide.)

5. Use a bulleted list on the 2nd to 5th slides according to the example. Do not use a list for the lines on the 3rd slide shown in the example, align these centred and highlight them using italics font style and a different font colour.

6. On the 2nd to 4th slides, insert the pictures next to the text and set their height to 10 cm keeping the aspect ratio in a way that they do not cover the text. On the 4th slide the three pictures should cover each other.

7. On the 4th slide, the three paragraphs should float in from the bottom on click, one after the other. Text “Music theory” should float in together with picture music.jpg, text “Number theory” with picture number.png and text “Geometry” with picture geo.jpg .

8. In the text of the 6th slide, put the numbers into upper index according to the example.

3. Chemicals The school laboratory is running out of chemicals. File data.txt contains the data of the

current order. Solve the following exercises using a spreadsheet processor.

During the solution take the followings into consideration. • You can perform auxiliary calculations to the right of column K. • Whenever possible, use a formula, function or reference in the solution to get a correct

result even if the source data are modified. • There are parts in the exercise that use the results of a previous exercise part. If you could

not solve the previous part completely, use its solution as it is, or enter a reasonable result and work on with that value. This way you can receive marks for that exercise part as well.

1. Import text file data.txt, which is UTF-8 encoded and tagged by tabs into the worksheet of the spreadsheet processor starting from cell A1. Save your work as chemicals in the default format of the spreadsheet processor. The name of the worksheet should be “order of chemicals”.

2. In the cells of range E2:E25, determine the gross unit prices using a formula. In the calculation of the gross unit price refer to the VAT value given in cell B27. Round the calculated values to integers using a function.

3. In the cells of range G2:G25, calculate the payable amount for each chemical using a formula, the gross unit price and the ordered quantity.

4. Expensive orders must be reconsidered. In the cells of range H2:H25, display a “!” sign using a formula if the payable amount exceeds 10000 Ft. Do not display anything in the cells in other cases.

5. In cell G27, calculate the total value of the order. 6. In cells B29 and B30, determine how many types of solid (“g”) and liquid (“ml”) chemicals

are in the order. 7. In cell B32, determine the highest payable amount. In cell B33, determine the name of the

chemical that belongs to the previous amount. 8. Format the table according to the following description and the example.

a. Set currency format in the cells of columns D, E and G that contain numbers and in cell B32. The currency values should be displayed without decimal figures.

b. In cells B29 and B30, display the word “items” after the numbers according to the example.

c. In the cells of ranges C2:C25, F2:F25 and H2:H25, align the contents centred horizontally.

d. In the cells of range A1:H1, align the text centred both horizontally and vertically.

e. Set a green background for the cells of range F2:F25 where the purchased amount is more than one.

f. Set a thin border around the cells of range A1:H25 but the border under rows 1 and 25 should be a double line.

g. Set a grey background in the cells of range A1:H1. Merge the cells shown in the example. In the cells of range A1:H1 wrap the text according to the example.

h. In the cells of range F27:G27, format the totalization according to the example. i. Set the width of columns A:H so that all data is readable. The width of columns

D, E and F should be the same. 9. Create a chart using the names of the chemicals and the payable amounts according to the

example. a. Highlight the highest column using a different colour. b. The scale of the y-axis is 2500. c. The chart should be displayed under the table covering the range shown in the

example. d. The title of the chart is text “Payable amount for each chemical”.

4. Waste transport Waste transport is an important public service in every settlement. The inhabitants receive

the waste transport calendar in advance for the whole year, it contains the type of waste to be transported, the date (there is only one transport each day, but several waste types can be transported then). Besides the calendar, the own waste transport data of a citizen for the whole year 2018 are available. The database contains these data.

1. Create a new database named transport. Import the three text files provided (calendar.txt, resdems.txt, services.txt) into the database with table names that correspond to the file names (calendar, resdems, services). The files are UTF-8 encoded text files tagged by tabs, their first line contains the field names. Upon importing set the suitable types and the keys. Add a unique key id to tables calendar and resdems.

Tables: calendar (id, sdate, servid)

id The identifier of the transport (autonumber), this is the key sdate The date of the transport service (date) servid The identifier of the type of waste to be transported (number)

resdems (id, demand, servid, quantity) id The identifier of the demand for waste transport (autonumber), this is the

key demand The day when the inhabitant moved the waste in front of the house (date) servid The identifier of the type of waste to be transported (number) quantity The amount of waste in transported units – e.g. number of bags, boxes,

containers (numbers) services (id, wtype, description)

id The identifier of the waste type (number), this is the key wtype The abbreviation of the waste type given by the service provider (text) description The detailed description of the waste type (text)

When solving the following exercises, save the queries and the report with the name given in brackets. Pay attention to displaying exactly the required fields in the solutions, do not display unnecessary fields. Hint for the date processing function used in the solution of the exercise:

Month(date) gives the month of the date as an integer between 1 and 12. 2. Create a query that displays the date of the last transport of community waste (type “com”)

from the calendar. (2last) 3. Christmas trees are transported as green waste in January. Create a query that displays the

transport dates of green waste (type “green”) in January from the calendar. (3christmastree)

4. Create a query that determines the number of occasions when the citizen had green waste (type “green”) transported during the whole year. (4green)

5. Using a query, determine the month when the citizen had the highest number of units of waste transported. If there are several such months, it is enough to determine one. (5most)

6. Create a query that determines the days of the calendar where both paper and plastic waste (type “pap” and “pla”) were transported. (6several)

7. Create a report about the number of occasions the different waste types were transported in each month based on the calendar and the data contents of the following example. Display the waste types in descending order by the number of transportations for each month. Pay attention to each data being completely visible. Ensure correct capitalisation. The report should be prepared based on a query. (7stat)
