EBK MODERN DATABASE MANAGEMENT,
- Access path A database table is composed of records and fields hold data. Data is stored in records. A field is a part of a record and contains a single piece of data for the subject of the record. The access path for finding the list of books is AUTHOR: AuthorID, Lname BOOKAUTHOR: AuthorID, ISBN BOOKS: Pubdate, ISBNarrow_forwardDistinguish between the advantages and disadvantages of a database approach to access control methods. What function does the database management system (DBMS) play in maintaining the database environment?arrow_forwardShould those who design databases be aware of any particular technique that, depending on the circumstances, could have the ability to greatly alter the effectiveness with which a database performs its functions?arrow_forward
- A database at a college is required to support the following requirements. Complete the information-level designfor this set of requirements. Use your own experience to determine any constraints you need that are not statedin the problem. Represent the answer in DBDL.a. For a department, store its number and name.b. For an advisor, store his or her number and name and the number of the department to which he or she isassigned.c. For a course, store its code and description (for example, MTH110 or Algebra).d. For a student, store his or her number and name. For each course the student has taken, store thecourse code, course description, and grade received. In addition, store the number and name of thestudent’s advisor. Assume that an advisor may advise any number of students but that each studenthas just one advisor.arrow_forwardIn what ways may the referential integrity of a database be broken? In what ways are you most prone to committing these mistakes?arrow_forwardDatabase Management Systems (DBMSs) are specially designed applications that interact with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is a software system designed to allow the definition, creation, querying, update, and administration of databases. Based on your understanding, discuss the FOUR (4) types of DBMS with relevant examples.arrow_forward
- Do database designers need to be aware of any particular technique that, when used in certain situations, has the potential to have a significant impact on a database's performance?arrow_forwardIs it safe to assume that a database is trustworthy if it meets entity and referential integrity criteria, or does this imply something else entirely?arrow_forwardFor the purpose of illustrating the structure of a database, either an E-R diagram or DBDL may be used. If that's the case, which strategy do you favor, and why?arrow_forward
- E-R diagrams or DBDLs may both be used to depict the structure of a database. Which approach do you find most appealing, and why?arrow_forwardAmong the six phases of the Database Life Cycle (DBLC), the phase that encompasses the utilization of the data dictionary is of interest?arrow_forwardIn order to keep a database in good shape, a supervisor's watchful eye is essential. So, what precisely does this entail into consideration? What does a day in the life of a database administrator typically look like?arrow_forward
