solved examples of normalization
Normalization is a process to reduce redundancy. By using normalization we can easily remove duplicate entries..
See the related link Answers dot com video for some examples of how to solve.
In DBMS the data is stored in the form of table . Each row in DBMS is known as tuple.
DBMS stands for database management system. DBMS reduce data redundancy as it checks if the data is duplicate and if duplicate then store it as a single record.
An insertion anomaly in a Database Management System (DBMS) occurs when certain data cannot be added to a database without the presence of other, unrelated data. This often arises in poorly designed relational databases, where dependencies between attributes lead to situations where new records cannot be created unless complete information is available. As a result, it can hinder data entry and lead to incomplete or inconsistent datasets. Proper normalization techniques can help mitigate insertion anomalies by organizing data more effectively.

dbms stands for data base management system whereas rdbms is relational data base management system. A Database Management System (DBMS) is collection of software programs which enable large, structured sets of data to be stored, modified, extracted and manipulated in different ways. Whereas Relational Database Managemet System (RDBMS) is a data structured in database tables, fields and records. Each RDBMS tables consist of database table rows.
Normalisation means make table very effective and usable means make table atomic ,unique primary key,not redundancy etc.

My sql, Microsoft sql , Microsoft Access, dBase, Filemaker pro are the examples for dbms and oracle and sql server are the examples for rdbms
i don't know answer of this ques. properly
An unnormalized relation in a Database Management System (DBMS) is a table that does not conform to the rules of normalization, meaning it may contain repeating groups or arrays of values within a single column. This structure can lead to data redundancy and anomalies during data manipulation. To improve data integrity and efficiency, unnormalized relations should be transformed into normalized forms, which separate data into distinct tables with relationships defined among them. Normalization helps eliminate redundancy and ensures consistency in the database.
Some advantages of relational database management systems (RDBMS) over traditional database management systems (DBMS) include data integrity through the use of constraints, normalization to reduce redundancy, support for ACID transactions, and standardized SQL language for data manipulation. RDBMS also offer scalability and flexibility for complex data structures and relationships.
Some examples are SQLServer , MySQL, Orcle
