What is Denormalization in DBMS? Denormalizationis a performance enhancement technique through database optimization by adding redundant data in a normalized database. The requirement is to enhance the performance of a database by adding more redundant data and not reducing it by normalization because ...
What is a Normalization P Can a database contain two identical records without a negative effect on the integrity of the database? Why or why not? What function does an attribute of an entity perform in a DBMS? (a) What is a multivalued dependency in DBMS? (b) Give an e...
DBMS (Database management system) In DBMS, the data is stored as a file in hierarchical form, the associated records don’t have any relation to each other. It does not support distributed databases and normalization of data is also not present. ...
Normalization means structuring the data keeps in a way that there is little or no repetition and relational. I know this is accomplished through a set of guidelines (normal forms) that minimize data anomalies. But there is drawback such as excess normalization can cause complicated query as wel...
The first step to store raw information in a database is to choose a DBMS. There are many different types of DBMSs, including relational, object-oriented, and NoSQL databases. Each of these types has its own advantages and disadvantages, and selecting the right one for your project is esse...
How do dynamic websites handle large amounts of data? Dynamic websites can efficiently handle large amounts of data by utilizing database management systems (DBMS) and implementing optimized data retrieval and storage techniques. By leveraging indexing, caching, and efficient database querying strategi...

17. How do you ensure data integrity and accuracy? Maintaining data integrity is critical for accurate analysis. Talk about techniques like data validation, data normalization, and data quality assessments that you use to ensure data is accurate and reliable. 18. What is your experience with data...
There are a few rules for database normalization. Each rule is called a “normal form.” If the first rule is observed, the database is said to be in “first normal form.” If the first three rules are observed, the database is considered to be in “third normal form.” The third...
(or less) the main concepts you need to understand to learn database design from scratch, summarized in Guru99's characteristic style. The page also serves as a starting point for further learning, linking to related pages where you can drill down on advanced concepts, such as normalization ...
