After E. F. Codd introduced the relational model, an expansive theory developed around the relational model pertaining to schema design and the expressive power of various relational languages. The enrollment table is related to the student table through stuId: The standard query language for RDBMS is Structured Query Language (SQL). -> WHERE deptCode = 'CSCI'; To distinguish the two version of mysql command line prompt, you may define: "C:\Program Files\MySQL\MySQL Server 8.0\bin\mysql.exe" -P 3308 %*. Such keys are known as Candidate keys.

So a key has two properties: Referential Integrity: When one attribute of a relation can only take values from other attribute of same relation or any other relation, it is called referential integrity. | CINF | Computer Information Systems | CSE | 5 | +-------+-------+ +------------+-------------------------------+ However, the structure can be changed (just like the structure of a building: remodeling). | MATH | Mathematics | CSE | 7 | | deptCode | deptName | schoolCode | numFaculty | +------------+-------------+------+-----+---------+-------+ 7 rows in set (0.00 sec), mysql> SELECT * FROM student; | 100002 | David | Hawk | CSCI | ITEC | 66 | 1011 | | 1018 | Art | Allister | ARTS | Assistant Professor | ; Relational Schema of STUDENT relation can be represented as: STUDENT (STUD_NO, STUD_NAME, STUD_PHONE, STUD_STATE, STUD_COUNTRY, STUD_AGE) mysql> SELECT * FROM grade; Each table of the column has a name or attribute. | deptCode | varchar(4) | NO | PRI | NULL | | | Benjamin | Yu | Information Technology | Lecturer | | 2002 | CSCI | 5333 | DBMS | 3 | from Simple domains are integers, strings. -> FROM faculty The relational model (RM) for database management is an approach to managing data using a structure and language consistent with first-order predicate logic, first described in 1969 by English computer scientist Edgar F. Codd, where all data is represented in terms of tuples, grouped into relations. ; ROLL_NO in STUDENT is a key. e.g;, if we delete a row from BRANCH with BRANCH_CODE ‘CS’, the rows in STUDENT relation with BRANCH_CODE CS (ROLL_NO 1 and 2 in this case) will be deleted. | 100006 | Lillian | Johnson | CINF | ITEC | 18 | 1015 | | 100007 | Ben | Zico | NULL | NULL | 16 | NULL | mysql> -- Faculty information from the department 'CSCI' →Values are (normally) atomic/scalar. | fName | lname | deptName | rank | 4 rows in set (0.00 sec) +-------+--------+--------+----------+---------------------+ All student names and the major codes. | BUS | Business | | 10006 | 2041 | Fall | 2019 | 1019 | D217 | SELECT DISTINCT s.lname, s.fname DBMS Relational Model concept with DBMS Overview, DBMS vs Files System, DBMS Architecture, Three schema Architecture, DBMS Language, DBMS Keys, DBMS Generalization, DBMS Specialization, Relational Model concept, SQL Introduction, Advantage of SQL, DBMS Normalization, Functional Dependency, DBMS Schedule, Concurrency Control etc. Following these steps in order. the record types. is a member of every domain. | ITEC | Information Technology | CSE | 4 | Note the terms table and relation can be ambiguous.
