Address Validation Imagine you get a data set from a client that contains addresses from 150 countries all around the world and  your task is to verify it, the data is stored in 3 fields – Address Line, City, and ZIP code. What you also have  available is an address verification solution for each country, but the data set does not include the country code.  Your task is to design a logic that will process the data and find the related country for each record, so they can  be run through the relevant validation component. Think of the most efficient way. Describe your solution  proposal ideally in an algorithmic way (e.g. using appropriate UML diagrams, pseudo-code, list of steps…) Hint: Running all of those 150 address verification components against each record is not considered efficient

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.
