    Ajánlott:

    Algorithm theory

    7. Objectives, learning outcomes and obtained knowledge To make students familiar with the operation and usage of database management systems. Application of the theory also in the engineering practice.

     

    8. Synopsis
    • Data and information, structured, non-structured and semistructured data

       

    • Database management systems, components, operation

       

    • Data Definition Language, Data Manipulation Language, Host language

       

    • Layered model of DBMS, principle of data independence

       

    • Data models, data modelling.

       

    • Entity-relationship model/diagram, attributes, relationship-types, constraints, specialization, weak entity sets.

       

    • Relational data model, relational algebra

       

    • Design of relational schemes from E/R diagram

       

    • Tuple relational calculus, domain relational calculus, safe expressions.

       

    • Functional dependencies, determinant, key, superkey, candidate key

       

    • Armstrong axioms, soundness and completeness, derivation rules

       

    • Normal forms of 0NF, 1NF, 2NF, 3NF, BCNF

       

    • Closure of dependency sets, closure of attribute sets

       

    • Decomposition of relational schemes. Lossless and dependency preserving decompositions. Decomposition in a given normal form.

       

    • Fundamentals of transaction management

       

    9. Method of instruction

    Interactive lectures in a small group with built-in practices 

    10. Assessment
    1. In the teaching period: 5-6 midterm tests, similar to real, numerical engineering problems. Scoring: from 1 to 5, 1 is the weakest grading. In case of any serious or fundamental mistake, the grading will be 1. Condition for the signature is passing the tests in average. The weakest test result will be ignored.

       

    2. In the exam period: Written exam, similar to the problems of the midterm tests. Scoring condition for successful written exam is at least 40%. Below 40% the exam is unsuccessful. 

       

    11. Recaps Accordig to the Code of Studies and Exams

     

    12. Consultations Individual consultation: upon agreement with the lecturer.

     

    13. References, textbooks and resources Recommended books:

     

    • Ullman: Principles of Database and Knowledge-Base Systems, Comp. Sci. Press vol. I-II, 1990.
