What the meaning of this word "Informatics"?

It is a process of retrieving & storing of data. 

Informatics is the science of information. As an academic field it involves the practice of information processing and the engineering of information systems. It studies the structure, algorithms, behaviour, and interactions of natural and artificial systems which store, process, access, and communicate information. The field considers the interaction between humans and information systems alongside the construction of computer interfaces. It also develops its own conceptual and theoretical foundations and utilizes foundations developed in other fields. As such, the field of informatics has great breadth and encompasses many individual specialisations including the more particular discipline of computing science.

1. In the most easiest words it can be defined as the collection, classification, storage, retrieval, and dissemination of recorded knowledge.

Based on the answers, what are the sources of electronic Informatics?

the science of processing data for storage and retrieval

agreed with mr.rizwan ,,, good day

“the study and application of information technology to the arts, science and professions, and to its use in organizations and society at large.” 

It is is a new and rapidly developing field. It uses computing to solve the big problems: privacy, security, healthcare, education, poverty, and challenges in our environment. All Informatics applications are computer-based.

Business informatics (BI) or organizational informatics is a discipline combining information technology  (IT), in formatics and management concepts.

As we live in the informatics era, the revolution of telecoms and information systems.. Informatic system is to update and retrieve the your comprehensive data any-time and any-where as long as you needed this information.

1. Informatics is the science of information  and  processing such information and it's systems.

The word INFORMATICS is practically a combination of2 broad concepts: INFORMATION and TECTICS. Most of the people 'mix-up' DATA with INFORMATION which is not correct. Data is transformed in to information to become usefull. E.g.: '2000 tons of cement' is a raw data, whereas '2000 tons of cement sold in a market of20000 tons' is informatiin coz it reveals the10% market share. Now, bringing Information should be SMART and TECTICAL with lowest input cost and highest output value. Therefore, the better the Tectical approach of bringing/converting Information, the higher the required goal achievement ratio ir potential. Hence the Tectics of bringing Information (useful) is termed as INFORMATICS.
