8 3. Final examination At the only secondary school of Iceburg many students applied for advance higher level final examination. The applications and later the results were recorded accurately at the school in the following database. 1. Create a new database with name erettsegi. Import the three supplied data tables (vizsgazo.txt, vizsga.txt, vizsgatargy.txt) with a name that corresponds with the file name (vizsgazo, vizsga, vizsgatargy). The first line of each file contains the field names. 2. Upon importing, set the proper formats and keys. If the existing fields can not be used as identifiers, insert a field with identifier function. Tables: vizsgazo (azon, nev, osztaly) azon the candidate s identifier (number), this is the key nev the candidate s name (string) osztaly the candidate s class (string) vizsga (vizsgazoaz, vizsgatargyaz, szobeli, irasbeli) vizsgazoaz the candidate s identifier (number) vizsgatargyaz the identifier of the subject (number) szobeli the score received on the oral examination (number) irasbeli the score received on the written examination (number) vizsgatargy (azon, nev, szomax, irmax) azon the identifier of the subject (number), this is the key nev the name of the subject (string) szomax the maximum score that can be received on the oral examination from the given subject (number) irmax the maximum score that can be received on the written examination from the given subject (number) Save the solution of the following exercises with the name given in brackets. 3. Create a query that gives the list of the 9 th grade students in alphabetical order according to the identifier of the class and within that according to the students name. Display every field with the exception of field azon. (3evf9) 4. Create a query that gives the subject(s) with the highest possible score in the written part. (4irmax) 5. Candidates who do not receive at least one tenth of the maximum score of the written part can not take the oral examination.

Create a query that gives the number of students of class 12/A who took the examination for each subject and also displays their average score in the oral and the average score in the written part. (6atlag) gyakorlati vizsga / május 17.

9 7. Insert a new field of a suitable number type with name teljesitmeny into table vizsga, which should store a real number between 0 and 1. Create a query that calculates the performance on each of the examinations in the field created in the previous step; performance is the ratio of the sum of the scores received in the oral and the written parts of the examination and the sum of the maximum scores that can be received in the oral and the written parts of the examination. (7teljesitmeny) 8. Create a query that based solely on the scores received for the written part of the examination in History displays the name of the 11 th and 12 th grade students whose score was higher than the school average. (8jobb) 9. Using a query, create a new table with name dombi for teacher Mr. István Dombi teaching Mathematics only to class C in the 11 th grade but to every class in the other grades. In the new table, list the score of the best written test for each class that teacher Mr. Dombi teaches. (9dombi) 10.

Create a query that gives the number of excellent marks in each class. (10jeles) 30 marks gyakorlati vizsga / május 17.

10 4. Protein Proteins are macromolecules, some of which catalyse the processes in living organisms. A protein contains hundreds of amino acids that connect to each other like the links of a chain. Several million types of proteins exist in nature. Every protein consists of the same twenty amino acids connecting in different quantities and in different order. The following table contains the principal data of amino acids, their names and the number of atoms building them up (every amino acid contains carbon, hydrogen, oxygen and nitrogen, some also contain sulphur): Name Abbreviation Key letter C H O N S Glycine Gly G Alanine Ala A Arginine Arg R Phenylalanine Phe F Cysteine Cys C Tryptophan Trp W Valine Val V Leucine Leu L Isoleucine Ile I Methionine Met M Proline Pro P Serine Ser S Threonine Thr T Asparagine Asn N Glutamine Gln Q Tyrosine Tyr Y Histidine His H Lysine Lys K Asparagine acid Asp D Glutamine acid Glu E Create a program with name feherje that solves the following exercises. Pay attention to saving the source code of the program as given in the path. 1. Load the data of the amino acids from file aminosav.txt. Each data is located in a separate line in the file; the file does not contain the names of the amino acids. If you can not load the data, take the first five data lines of the above table as constant and work with them. The first few data are: Gly G Ala A gyakorlati vizsga / május 17.

11 2. Determine the relative molecular mass of the amino acids, given that the atomic mass of carbon is 12, that of hydrogen is 1, that of oxygen is 16, that of nitrogen is 14 and that of sulphur is 32. For example in the case of glycine the relative molecular mass is = 75. Write the results of the following exercises on the screen, and into file eredmeny.txt as well. Before the exercises you should indicate the exercise number (for example: 4th exercise). 3. Arrange the amino acids into increasing order based on their relative molecular mass. Write the three-letter identifier and the molecular mass of the amino acids on the screen and into file eredmeny.txt. The identifier and the corresponding molecular mass should be written into the same line separated by a space. 4. File bsa.txt contains the amino acid sequence of protein BSA using key-letter notation. (The protein chain contains at most 1000 amino acids.) Determine the empirical formula of the protein (that is, the number of C, H, O, N and S in it). When determining the formula, please take into consideration that when two amino acids connect, for every connection one water molecule (H 2 O) leaves the chain. Write the empirical formula on the screen and into file eredmeny.txt in the following format: For example: C H O 4234 N 8210 S 2231 (If the reading of file bsa.txt is unsuccessful, store letters G,A,R,F,C ten times one after the other instead of it and solve the exercises for this chain.) 5. The sequence of amino acids in proteins is determined by a splitting procedure. Certain enzymes split the protein molecule after certain amino acids. For example enzyme Chimotripsine splits the molecule after Tyrosine (Y), Phenylalanine (W) and Thryptophane (F). Determine and display on the screen the length of the longest segment of the BSA chain when split by the Chimotripsine enzyme and also its position in the original chain (the place of its first and last amino acids in the sequence). Name the displayed data upon displaying, for example: start position:. 6. Another enzyme (Factor XI) splits after Arginine (R), but only if it is followed by Alanine (A) or Valine (V). Determine the number of Cisteines (C) in the first protein chain segment produced in the splitting process. Display the answer as a full sentence on the screen. 45 marks gyakorlati vizsga / május 17.
