Why we Use MongoDB?

Here is some highlights:-

For more kindly visit  mongodb site:-
    • Document-oriented
      1. Dynamically-typed (schemaless) for easy schema evolution
      2. Embedded documents and arrays reduce need for joins
      3. Documents (objects) map nicely to programming language data types
    • High performance
      1. Indexes including indexing of keys from embedded documents and arrays
      2. Optional streaming writes (no acknowledgements)
      3. No joins and embedding makes reads and writes fast
    • High availability
    • Easy scalability
      1. Eventually-consistent reads can be distributed over replicated servers
      2. Automatic sharding (auto-partitioning of data across servers)
        • Reads and writes are distributed over shards
        • No joins or multi-document transactions make distributed queries easy and fast
    • Rich query language

Why Dozer Framework (Bean Manipulation)

Why Dozer ? Let us think about a situation that you have a source bean which contains lot of fields and the source bean belongs to a different project or module. Now you want to expose the bean to  the outside world as a part of your web service REST service development. It is not advisable to do it. There may be the following reasons. The source bean is not serialized and a final class. The source system does not allow doing it because of security breach. The source bean is very heavy and contains lot of nested beans. The source bean has fields of different types which may not be required for other system. The source bean has lot of fields; some of them are not required. Scenario to use Dozer Suppose You want to make a REST call or web service call to get the minimal account details of a person. But the source system has a bean called “Acc0untBean” which contains many sensitive information like person’s internet banking passw0rd, PAN no or social sec...

Difference between Micro Service and Web Services

Micro web services and Web services are two different concepts of application development architecture, Which can be differentiated from it's development style and layered architecture.In This article I will explain the difference between Web Services and Micro Services Web Services ? Web services are services that are made available from a business's Web server for Web users or other Web-connected programs. it is a way to expose the functionality of an application to other application, without a user interface. It is a service which exposes an API over HTTP. Web Services allow applications developed in different technologies to communicate with each other through a common format like XML, Jason, etc.  Web services are not tied to any one operating system or programming language. For example, an application developed in Java can be used in C#, Android, Php etc., and vice versa.  Web Service is a connection technology, a way to connect services together into a ...
