Types of database architectures

A Database Architecture represents the Database Management System’s (DBMS) design (schema). The DBMS architecture makes it easy to understand the components involved in the database system and their relations. The DBMS architecture may vary based on the system on which it runs. Some systems contain both client and server machines whereas some run only on a server machine. Based on the architecture, the system can be classified as centralized, decentralized, or hierarchical.

A passenger aircraft is composed of several millions of individual parts and requires thousands of persons to assemble. A four-lane highway bridge is another example of complexity. The first version of Word for Windows, a word processor released by Microsoft in November 1989, required 55 person-years, resulted into 249,000 lines of source code, and was delivered 4 years late. Aircraft and highway bridges are usually delivered on time and below budget, whereas software is often not. Discuss what are, in your opinion, the differences between. Developing an aircraft, a bridge, and a word processor, which would cause this situation.
It is our contention that the taxonomy proposed by Flynn could be enhanced by the inclusion of an additional tier. What distinguishes advanced computers from less sophisticated ones?
Yet, in contrast to the vast majority of actual computer systems, the OSI model assumes a higher number of levels. The reason for this is inherent in the nature of computing systems. Avoid utilizing as many layers as you can if at all feasible. If we cut down on the overall number of layers, what are some of the possible problems we could encounter?
In contrast, the OSI model requires a greater number of layers than are implemented in the vast majority of modern computer systems. Why don't we attempt to reduce the number of strata with which we are currently dealing? Is there anything you can think of that might not work out as desired if you use fewer layers?
While the OSI model has value, most current computers lack the components required to completely execute it. We might use fewer, simpler layers that are easier to maintain. Can you see any potential issues if we used less layers?

When subsystems of large computer processes and programs are divided into smaller units, do they make sense? What are the benefits of this way of system segmentation?
Even while the OSI model is useful, most modern computers do not have all of the components that are necessary to properly execute it. It's possible that we'll utilise fewer, more straightforward layers that are easier to manage. Do you foresee any possible problems that may arise if we employed fewer layers?
