Advantages of Database System:
A database is a collection of interrelated data and the advantages of a database are ensured efficiency, standardized data, maintainable data, integrated data, reduced redundancy of data.
can't get corrupt
Use to keep infomation
The advantages of Cost and Risk Database Approach include being personalized and specialized. It also involves conversion costs and management cost.

There are currently 3 general categories of data base management systems in use today:relational database systemsmultidimensional database systems (often referred as 'cubes')object oriented database systemsPrior to the success of relational database systems (early 80's) there were also hierachical database systems and network (aka CODASYL) database systems.
1 Explain architecture of Distributed Database systems? Also, explain the reasons for building distributed database systems?
A database is a collection of interrelated data and the advantages of a database are ensured efficiency, standardized data, maintainable data, integrated data, reduced redundancy of data.
There are many advantages of performing a database normalization. Some of the advantages include faster index searching, data commands are faster with less indexes and a more compact database with less null data.

Database systems can be either referential, flat or heiarchial.
Advantages -- many already exist;good for simple applications;veryefficient efficientDisadvantages -- data duplication;hard to evolve;hard to build forcomplex complex applications applications
There are lot of Database Management systems that run on Linux, but MySQL and PostgreSQL seem to be the mostly used Database Management systems.
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.

The database can be of two types either distributed or centralized . In distributed database the data is in different systems. In centralized database the data is in a single central system.We can categorize database as either distributed or centralized . In centralized database the data is in a single centralized system. While In distributed database the data is in different systems .
