In a database management system (DBMS), a serializable schedule is a sequence of database actions (read and write operations) that does not violate the serializability property. This property ensures that each transaction appears to execute atomically and is isolated from other transactions' effects....
A database schema design technique that functions to increase clarity in organizing data is referred to as normalization. Normalization in DBMS modifies an existing schema to minimize redundancy and dependency of data by splitting a large table into smaller tables and defining the relationship between ...
In 4NFF, R should be (no multi-valued dependency exists). Unable to undergo lossless decomposition (join dependency)PJNF (Project-Join Normal Form) ExampleConsider the database table R below having the schema R (supplier, product, consumer). The primary key is a combination of all three att...
(a) What is a multivalued dependency in DBMS? (b) Give an example. What is data granularity? What does a big data architect do? What are the differences of storage architecture between DBMS and OODBMS? What is the difference between a database Field and a database Record?
(a) What is a multivalued dependency in DBMS? (b) Give an example. What is component architecture? What is SOA architecture? What is database design? What are the SDLC phases? Explain. Which chart is best used to display data that changes over time? (a) Line Chart. (b) Column Chart...

DBMSDatabaseBig Data Analytics Shadow paging is one of the techniques that is used to recover from failure. We all know that recovery means to get back the information, which is lost. It helps to maintain database consistency in case of failure. Concept of shadow paging Now let see the ...
Data Models in DBMS TheData Modelis defined as an abstract model that organizes data description, data semantics, and consistency constraints of data. The data model emphasizes on what data is needed and how it should be organized instead of what operations will be performed on data. Data Model...
However, if you look at the implementations of isolation in practice, you see that serializability is rarely used, and some popular databases (such as Oracle) don't even implement it.So what does isolation actually mean? Well, in practice, many database systems allow you to choose your ...
In an enterprise context, it is used for tasks like real-time analytics, large-scale data processing, and maintaining application response times. Challenges and Limitations While Query Optimization offers significant benefits, it also has limitations such as handling complex queries, dependency on ...
