Which one of the following is not an example of dbms

Introduction To Database Management System A database management system (DBMS) is a computer program designed to manage a large amount of structured data, and run operations on the desired data requested by the users. The best example of DBMS is Banking. All the transactions that take place are based on a defined software program which keeps track of all the data. The concept of DBMS is an important topic from a Computer Knowledge perspective. It also forms an integral part of the syllabus for major competitive exams. Thus, one must carefully go through the concept. In this article, we bring you an introduction to the Database Management System along with its types and functions. Also, the advantages and components of a DBMS have been discussed in detail. Some sample questions on this topic have also been given further below in this article. Upgrade your Computer Awareness and learn more about the various programs and applications with the help of links given below: • • • • • The core of any database management system is the data itself. Another important aspect regarding DBMS is the difference between data and information. Data: It is the unorganised facts which need to be compiled to form meaningful information Information: Once the data is processed and made into a structured context, it is called information. Database Management Software Notes PDF:- Download PDF Here Let us now move on to the detailed study of what a database management system is and understand its i...

| 02 Jan, 2023 Normalization in DBMS: 1NF, 2NF, 3NF, and BCNF [Examples] When developing the schema of a relational database, one of the most important aspects to be taken into account is to ensure that the duplication of data is minimized. We do this by carrying out database normalization, an important part of the database schema design process. Here, we explain normalization in DBMS, explaining 1NF, 2NF, 3NF, and BCNF with explanations. First, let’s take a look at what normalization is and why it is important. What is Normalization in DBMS? Database normalization is a technique that helps design the schema of the database in an optimal way. The core idea of database normalization is to divide the tables into smaller subtables and store pointers to data rather than replicating it. Why Do We Carry out Database Normalization? There are two primary reasons why database normalization is used. First, it helps reduce the amount of storage needed to store the data. Second, it prevents data conflicts that may creep in because of the existence of multiple copies of the same data. If a database isn’t normalized, then it can result in less efficient and generally slower systems, and potentially even inaccurate data. It may also lead to excessive disk I/O usage and bad performance. What is a Key? You should also be aware of what a key is. A key is an attribute that helps identify a row in a table. There are seven different types, which you’ll see used in the explanation of the variou...

Prerequisite: In a relational database management, functional dependency is a concept that specifies the relationship between two sets of attributes where one attribute determines the value of another attribute. It is denoted as X → Y, where the attribute set on the left side of the arrow, X is called Determinant, and Y is called the Dependent. roll_no name dept_name dept_building 42 abc CO A4 43 pqr IT A3 44 xyz CO A4 45 xyz IT A3 46 mno EC B2 47 jkl ME B2 From the above table we can conclude some valid functional dependencies: • roll_no → → roll_no, dept_building → roll_no, etc. Armstrong’s axioms/properties of functional dependencies: • Reflexivity: If Y is a subset of X, then X→Y holds by reflexivity rule Example, 3. Multivalued Functional Dependency In Multivalued functional dependency, entities of the dependent set are not dependent on each other. i.e. If a → is a multivalued functional dependency, since the dependents name & age are not dependent on each other(i.e. name → age or age → name doesn’t exist !) 4. Transitive Functional Dependency In transitive functional dependency, dependent is indirectly dependent on determinant. i.e. If a → b & b → c, then according to axiom of transitivity, a → c. This is a transitive functional dependency. For example, enrol_no name dept building_no 42 abc CO 4 43 pqr EC 2 44 xyz IT 1 45 abc EC 2 Here, enrol_no → dept and dept → building_no. Hence, according to the axiom of transitivity, enrol_no → building_no is a valid function...

The correct answer is Microsoft Excel. Key Points • Database Management System (DBMS) • Itis system software for creating and managing databases. • Itis a software designed to store, retrieve, define, and manage data in a database. • Itessentially serves as an interface between databases and users or application programs, ensuring that data is consistently organized and remains easily accessible. • Itfollows the concepts of Atomicity, Consistency, Isolation, and Durability (normally shortened as ACID). • Itsupports a multi-user environment and allows them to access and manipulate data in parallel. • Types of DBMS Systems are: • Hierarchical Database • Network Database • Relational Database • Object-Oriented Database • MySQL, Oracle, andMongoDB are the example of DBMS. Additional Information • Microsoft Excel is an electronic spreadsheet program. • The files created in Microsoft Excel is known as a workbook. • A spreadsheet is a computer application used for organization, analysis, and storage of data in tabular form.
