NEW QUESTION # 65
A database professional is considering denormalizing a database. Which of the following documents should be used to analyze the database's structure?
  • A. UML diagrams
  • B. ERD
  • C. SOP
  • D. Data dictionaries
Answer: B
Explanation:
The document that should be used to analyze the database's structure is an ERD. An ERD, or Entity Relationship Diagram, is a graphical representation of the entities (tables), attributes (columns), and relationships (constraints) in a database. An ERD helps to visualize the structure and design of the database, as well as the dependencies and associations among the tables. An ERD can also help to evaluate the level of normalization of the database, which is a process that organizes data into tables and columns to reduce redundancy and improve consistency. By using an ERD, a database professional can consider denormalizing a database, which is a process that introduces some redundancy or duplication of data to improve performance or simplify queries.
The other options are either different types of documents or not related to the database's structure. For example, an SOP, or Standard Operating Procedure, is a document that describes the steps and procedures for performing a specific task or operation; a data dictionary is a document that describes the metadata (information about data) of a database; a UML diagram is a graphical representation of a software system or its components using the Unified Modeling Language (UML).

NEW QUESTION # 66

var name;
  • A. var SQL = "Select * from sample_database where name = ' " + name + " '
    " ;
  • B. name= request.form ("name");
    var SQL = "Select * from sample_database where name = ' " + name + " '
    " ;
    var name;
  • C. name= request.form ("name");
    var name;
  • D. var name = "Select * from sample_database where name = ' " + name + " '
    " ;
    var name;
Answer: B
Explanation:
This code directly concatenates user input into an SQL query string without validation or parameterization, making it vulnerable to SQL injection attacks.
