IT Companies:

·         Product Based Company: These companies develop the own IT products based on the market needs and sells to the other company / release the product directly into the market. Ex: IBM / ORACLE / Microsoft

·         Service Based Company: These companies developing the IT products based on their client requirements. Ex: TCS / CTS / WIPRO

Technical Vs Functional Consultant

·         A functional consultant is one who interpret business processes, write specs, and did configuration. The functional consultant was typically the person that configured the system to reflect business requirements.

·         A technical consultant was typically a programmer or basis person. The former was a person who developed programs specified by functional people to fill gaps between business processes and SAP. The basis people made sure the lights stayed on and the system worked.

·         Today, these roles are merging, increasingly to survive in the world of SAP you need to be both, functional and technical. Its not good enough to be one or the other. This is particularly true with CRM.

Developer Vs Programmer:

In a nutshell, the basic difference between a developer and a programmer is the scope of their work. Developers are more involved with and have a greater understanding of the full project scope. Programmers are involved in a specific part of the project — coding.

Developer is the one who writes the coding …. Programmer is the one who writes the scripting.

Apple/Iphone dev.:

Environments: Xcode, Objective-C, Swift, Core Data, Realm, Storyboards, Bluetooth devices, Trello, Slack

Software Developer: Implementation-Coding

Who involves all phases of the software development (Design / coding / unit testing)

Certification: It will differs based on development skill / tool

Fullstack is combination of Frontend and backend)

Front-end & Back-end:

Front – End: It will interface between the User and Backend… Front-End is responsible for collecting the inputs in various forms from the user. Between H/W and End-User there is a different kind of layers… To make end user as most User friendly it will help. Eg: Java / HTML / ASP / Ruby / Mainframe

Back-End: It’s a Database which can be used by the End-User in-directly through external application. Use to store the database. Eg: SQL, Oracle, PSQL, Sybase, DB2 DB

Front-End Technologies: 

HTML/HTML5, CSS/CSS3, JavaScript (NodeJS, AngularJS, ReactJS, VueJS), Jquery, VBScript, AJAX, Twitter BootStrap/BootStrap4, Express.js- framework for Node.js, (ASP.net Active Server Pages.NET)

Back End technologies: 

C/C++, C#, PHP, Python, Ruby on Rails(RoR), Java, Sql, Perl

Databases: My SQL, NO Sql, Oracle 12c, PostgreSQL, MongoDB,  MariaDB, IBM DB2, SAP HANA

Databases:

A) SQL

B)NoSQL

The main difference between these two is that SQL databases, also called Relational Databases (RDBMS), have relational structure and NoSQL doesn’t use relations. SQL databases are vertically scalable, which means one ultimate machine will do the work for you. On the other hand, NoSQL databases are horizontally scalable, which means multiple smaller machines will do the work for you.

A)      SQL (Structured Query Language)/Relational Databases (RDBMS):

       MySQL, PostgreSQL, Oracle 12c, Sybase,  Ms SQL server (Microsoft SQL Server), Access, Ingres

B)       NoSQL Databases:

1.       MongoDB

2.       Cassandra

3.       Redis

4.       HBase

5.       Neo4j

6.       Oracle NoSQL

7.       DynamoDB

8.       Couchbase

9.       Memcached

10.   CouchDB

CMS(Content Management System): 

Wordpress, Joomla, Drupal, Magento, Blogger, Shopify, Bitrix, Typo3, Squarespace, Prestashop, DotNetDuke; SQL (MySQL or PostgreSQL) and NoSQL (MongoDB or Cassandra)

Framework: 

basic structure / Platform, A framework is a collection of programs that do something useful and which you can use to develop your own applications. A framework guides you on how to do something (like a predefined way of doing things)

Database: SQL, PostgreSQL, NoSql, MongoDB, Cassandra

Big Data : Hadoop, NoSql, Apache Spark, Apache Storm, Cassandra, rapidminer, Mongo DB

Big data is a term for data sets that are so large or complex that traditional data processing application softwareis inadequate to deal with them. Big data challenges include capturing data, data storage, data analysis, search, sharing, transfer, visualization, querying, updating and information privacy.

Hadoop is an open source, Java-based programming framework that supports the processing and storage of extremely large data sets in a distributed computing environment. It is part of the Apache project sponsored by the Apache Software Foundation.

Cloud Computing: 

AWS (Amazon Web Services)/ Microsoft Azure/Google Cloud Platform

IaaS (Infrastructure-as-a-Service), PaaS (Platform-as-a-Service), SaaS (Software-as-a-Service)

Azure is a Paas public cloud computing platform—with solutions including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) that can be used for services such as analytics, virtual computing, storage, networking, and much more.

Azure DevOps is the evolution of VSTS (Visual Studio Team Services).

Simply put, cloud computing is the delivery of computing services—servers, storage, databases, networking, software, analytics and more—over the Internet (“the cloud”). Companies offering these computing services are called cloud providers and typically charge for cloud computing services based on usage, similar to how you are billed for water or electricity at home.

Sales CRM:

The Salesforce cloud is an on-demand customer relationship management (CRM) suite offering applications for small, midsize and enterprise organizations, with a focus on sales and support.

Amazon Web Services (AWS) is a secure cloud services platform, offering compute power, database storage, content delivery and other functionality to help businesses scale and grow.

Artificial Intelligence (AI):

NLP Natural Language Processing NLP Ai, AI artificial intelligence, ML Machine learning, DL DL is a subset of ML, which is also a subset of AI.
