Centalized database organizes all of an organization data , it is like a mainframe computer. Like in any company or firm all the data is integrated in to a single system.
There are three database models. The three database models are as follows : 1) relational 2) network data 3) hierarchical
Its a place where a database is implemented>
Centralized System Architecture:Centralized means the data is in one place.Centralized database - that is have one large computer to which you connect a large number of terminals. Everyone is working directly on the machine that holds the database.Client-server Architecture:Client server just means the clients are in a different place than the data. It simply means the database is considered one unit managed by one DBMS in one location and to which clients connect.Client/Server DB system relies [traditionally] on a single database-server, which passes information to a client machine, where some of the data processing is doneType your answer here...
You could have a text field called Name. You could have a date field called Date of Birth.
give the advantages and dis advantages of a centralized registry?
what are the disadvantages of centralized database system
Distributed databases offer advantages such as improved scalability, increased availability, and better fault tolerance compared to centralized databases. They also provide better performance by reducing network latency and enabling data to be processed closer to where it is needed. Additionally, distributed databases can offer better data security by replicating data across multiple locations.
Examples of centralized information architectures include traditional data warehouses, where all data is stored and managed in a central repository. Another example is a centralized content management system, where all digital content is stored and managed in a central location. Additionally, centralized databases, where all data is stored in a single database server, are also common examples of centralized information architectures.
Centralized databases have the advantage of being fast, and easy to manage while information is easy to manage. However, it has its disadvantages as well. All the information must be stored on a server and if that server happens to fail, no one can access the database. Having outside servers can remove this issue.

the centralized directory database in the domain model is NTDS.DIT(directory information tree) but for the local sstem not connected to domain is SAM
Centralized databases offer simplified data management, easier maintenance, and increased data consistency due to a single point of control. They also provide better security measures by having a centralized system for monitoring and implementing security protocols. Additionally, centralized databases promote better scalability and efficiency in handling large volumes of data.
Some disadvantages of centralized data processing include the risk of a single point of failure, as the entire system can be compromised if the centralized data processing center experiences a technical issue or outage. Additionally, centralized data processing may lead to slower response times, as data has to be transmitted back and forth between the center and the various endpoints. There is also concern about data security and privacy, as centralizing data in one location can increase the risk of unauthorized access and breaches.
the porpose of database is to sstore consistent,standardise data at a centralized place in a secure manner and to facilitatedata sharing among all the applications requiring it.
