Agile

 The Agile movement proposes alternatives to traditional project management. Agile approaches are typically used in software development to help businesses respond to unpredictability which refer to a group of software development methodologies based on iterative development, where requirements and solutions evolve through collaboration between self-organizing...

Rapid Application Development Model

 The Rapid Application Development Model was first proposed by IBM in 1980’s. The critical feature of this model is the use of powerful development tools and techniques.A software project can be implemented using this model if the project can be broken down into small modules wherein each module can be assigned independently to separate teams. These modules can finally be...

Query Language

In simple words, a Language which is used to store and retrieve data from database is known as query language. For example – SQLThere are two types of query language:1.Procedural Query language2.Non-procedural query language1. Procedural Query language:In procedural query language, user instructs the system to perform a series of operations to produce the desired results....

Relational Calculus: Tuple Relational Calculus, Domain Relational Calculus

 Relational CalculusRelational calculus is a non-procedural query language. In the non-procedural query language, the user is concerned with the details of how to obtain the end results.The relational calculus tells what to do but never explains how to do.Types of Relational...

Relational algebra

 Relational algebra is a procedural query language, which takes instances of relations as input and yields instances of relations as output. It uses operators to perform queries. An operator can be either unary or binary. They accept relations as their input and yield relations as their output....

Unit 2: Keys

Types of keys in DBMS Super Key – A super key is a set of one of more columns (attributes) to uniquely identify rows in a table. Candidate Key – A super key with no redundant attribute is known as candidate keyPrimary Key – A primary is a column or set of columns in a table that uniquely identifies tuples (rows) in that table. PPTStudy Material:10 Different Keys in DBMSFinding...

Unit 2: Integrity Constraints

 Integrity ConstraintsIntegrity constraints are a set of rules. It is used to maintain the quality of information.Integrity constraints ensure that the data insertion, updating, and other processes have to be performed in such a way that data integrity is not affected.Thus, integrity constraint is used to guard against accidental damage to the database.PPThttps://drive.go...

Unit 2: Relational Model (Introduction)

 Relational Model was proposed by E.F. Codd to model data in the form of relations or tables. After designing the conceptual model of Database using ER diagram, we need to convert the conceptual model in the relational model which can be implemented using any RDMBS languages like Oracle SQL, MySQL etc. So we will see what Relational Model is....
