Concept explainers

Intermediate SQL Concepts

A query is a request for data or information from one or more database tables. This information could be presented in the form of pictorials, graphs, or complicated findings which helps in easy interpretation. Structured Query Language (SQL) is the most widely used programming language for retrieving and organizing data from relational databases. Collection of tables with rows and columns is referred to as a database. SQL is the language of databases. It makes it easier to extract specific data from databases, which can then be used for analysis.

For these questions, there exists 4 relations: R(A, B,C), S(C,D), T(D,E,F), and U(B,G). The size of attributes A to D are 10 bytes each, attributes E and F have size 100 bytes, and attribute G has size 1000 bytes. The blocks size is 16,384 bytes with no spanning. Relation R has 100,000 tuples, relation S has 20,000 typles, T has 5,000 tuples, and relation U has 150,000 tuples. Other statistics: V(R,C)=10,000, V(S,D)=500, V(R,B)=1000. Assume that attributes with the same name can be joined across relations (and duplicates are eliminated during a join), and the fırst attribute is the primary key of the relation. Answer the following questions about calculating intermediate result sizes. Answer the question in terms of the # of tuples and the # of blocks. Question 3 What is the size of op=10(S)?

Consider a relation named as BOOK that contains data about the books in a library. BOOK relation was initially created with the attributes BookID (an id that library assigns), ISBN, CopyNr (used to differentiate copies of the same book), Title, PublYear, Author, and AuthorBornYear. Primary key: BookID, CopyNr and Author Candidate key: ISBN, CopyNr and Author Below you see dependencies of attributes: Dependency 1 (D1): ISBN, Title, PublYear, AuthorBornYear were dependent on BookID, CopyNr and Author Dependency 2 (D2): Title and PublYear were dependent on BookID, CopyNr Dependency 3 (D3): AuthorBornYear was dependent on Author First determine which normal form (1NF, 2NF, 3NF or BCNF) the above relation is, and why. Then, if necessary, convert the above relation to the highest normal form (BCNF). Write any assumptions that you make.
