A centralized database is one in which all the data of an organization is stored in a single mainframe computer. One disadvantage of this database is that if the centralized database is corrupted, all the data will be lost.
With centralized data processing, one advantage is that you can control all the processing for your business from one location. If you're working on a terminal and it goes down, you can log into another one and keep working. On the other hand, if the central computer goes down, no work can be done on any of the terminals. This is the biggest disadvantage.
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 .
Some disadvantages of data integrity can include increased storage requirements, slower processing speeds due to the need to validate data, and potential complexity in managing and enforcing data integrity rules across an organization. Additionally, strict data integrity measures can sometimes limit flexibility and agility in data operations.
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.
Advantages of gathering large quantities of data include more insights, better decision-making, and improving predictions. However, disadvantages can include increased storage and processing costs, potential privacy concerns, and the challenge of ensuring data quality.

disadvantages in data manual processing
Centralized processing makes it easier to maintain security and standards in addition to making duplication less likely. The biggest disadvantage of centralized processing is that if the system goes down, then all systems may be inaccessible.

The processing performed in one computer or in a cluster of coupled computers in a single location. Access to the computer is via "dumb terminals," which send only input and receive output or "smart terminals," which add screen formatting. All data processing is performed in the central computer. Centralized processing evolved from the first computers in the 1950s, which were stand-alone with all input and output devices in the same room. Starting in the 1960s, terminals were added throughout a company's headquarters and branch offices, and each terminal was wired into the central machine, whether local or via a remote communications method.

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.
Centralized Data Processing (CDP) uses Centralised computers, processing, data, control, support. The advantages are Economy for equipment and personnel, Lack of duplication, Ease in enforcing standards, security. In Distributed Data Processing (DDP)Computers are dispersed throughout organisation. Which allows greater flexibility in structure, More redundancy and More autonomy. Hi, Centralized data processing is a Computer data processing architecture where data processing support is provided by one or a cluster of computers, generally a large. dedicated computers, located in a central data processing facility. In a centralized architecture, each person is provided with a local terminal that is connected by a communications facility to the central data processing facility. A fully centralized data processing has following features: 1. Centralized computers 2. Centralized processing 3. Centralized Data 4. Centralized Control 5. Centralized Staff Support A Distributed data processing facility is one in which computers, usually smaller computers, are dispersed throughout the organization. The objective of such disperse is to process information in a way that is most effective based on operational. Therefore, DDP (Distributed Data Processing) features: 1. A collection of terminals link together by some kind of communication link and has no main central computer or not fully (minimal) depend on central computer. 2. Processing of information is happening on each terminal and send results to a main server for store and retrieval purposes. 3. Data may duplicate as data may store in locally or in remote server. 4. Local computer operator can control the machine in his premises. 5. Separate staff will maintain central computer (if there any) where other terminals may control by one or few other members.
