GraphQL

-

GraphQL is a query language for API, and a server-side runtime for executing queries using a type system defined for data.

GraphQL isn't tied to any specific database or storage engine and is instead backed by existing code and data.

PL/SQL

PL/SQL PL/SQL stands for Procedural Language extensions to the Structured Query Language (SQL). PL/SQL can execute a number of queries in one block using single command. One can create a PL/SQL unit such as procedures, functions, packages, triggers, and types, which are stored in the database for reuse by applications. The PL/SQL engine resides in the Oracle engine. The Oracle engine can process not only single SQL statement but also block of many statements. Structure of PL/SQL Block: DECLARE     declaration statements; BEGIN     executable statements EXCEPTIONS     exception handling statements END; / Example : SET SERVEROUTPUT ON; SQL> DECLARE        var varchar2(40) := 'I love GeeksForGeeks' ;      BEGIN        dbms_output.put_line(var);      END;      / PL/SQL Functions PL/SQL functions are reusable blocks of code that can be used to perform specific tasks. They are...

JAVA8 Features

Java8 Features 1) Lambda Expressions : Concise functional code using ->. Lambda Expression basically expresses an instance of the functional interface, Lambda Expression provides a clear and concise way to represent a method of the functional interface using an expression. 2) Functional Interfaces : Single-method interfaces. An interface that contains only one abstract method is known as a functional interface. There is no restriction, that can have n number of default and static methods inside a functional interface. A functional interface is an interface that contains only one abstract method.  @FunctionalInterface annotation is used to ensure that the functional interface can’t have more than one abstract method. Runnable, ActionListener, and Comparable are some of the examples of functional interfaces.   Runnable –> This interface only contains the run() method.   Comparable –> This interface only contains the compareTo() method.   ActionListener –> ...

Build Automation

-
ANT: Ant was the first build tool released in 2000. Ant was developed on procedural programming idea. Ant was improved with an ability to accept plug-ins and dependency management over the network, with the help on Apache-IVY. Drawbacks: 1) XML is used as a format to write the build scripts. 2) Being hierarchical is not good for procedural programming, and 3) XML is relatively unmanageable.   MAVEN: Maven was introduced in 2004. Maven relied on the conventions and was able to download the dependencies over the network. Benefits : Life cycle of Maven, while following the same life cycle for multiple projects continuously. Problems: 1) Maven does not handle the conflicts between versions of the same library. 2) Complex customised build scripts are difficult to write in Maven, as compared to writing the build scripts in ANT. GRADLE : Gradle came into picture in 2012 Features  Declarative builds and build-by-convention 1) Gradle is available with separate Domain Specific Language ...
