medical data are often acquired for each of giving additional information, as well as for their diagnoses, prognoses, treatment procedures, and outcomes, the development of storage and methodologies capable of gathering and maintaining relevant medical data is additionally challenged.

      Healthcare is a multi-dimensional system established with the sole aim for the prevention, diagnosis, and treatment of health-related issues or impairments in human beings. These are the main parts of a healthcare system; you have the medical personnel (doctors and nurses), which supports the healthcare facilities (clinics and hospitals for delivering medicine and technologies), and then you have financing supporting them. The physicians who practice in different areas of healthcare, such as dentistry, midwifery, and psychology are health professionals known as so-aspirants. Since there are so many issues with healthcare, it depends on the level of urgency and extent of treatment to expand. The professional first; their clientele receives it from a variety of treatment options, complex and invasive conditions, both from non-professional physicians and private hospitals, and as well as from the general medical community (non-specialized as well as well as private) (quaternary care) [17]. A doctor, nurse, researcher, radiologist, and lab technician are all needed to have separate needs and are held responsible for a number of different types of information. For example, that of patient history (diagnosis and prescriptions), other medical and clinical (data obtained from imaging and laboratory tests), and personal history (all those that may apply), data on other medical issues as opposed to previous record keeping methods that typically utilized handwritten or typed case notes, in which these medical records were stored. This earlier method was not done, this could be compared to the results of a medical tests which are traditionally kept in an inadequate electronic systems. For reference, an ancient papyrus from Egypt suggests that this was standard practice even a figure in the time of 1600 BC [18]. In Stanley Reiser’s opinion [19], the medical case histories do an excellent job of recording everything in relation to the story of the patient, the family, and the physician, while preserving the dynamics of the illness.

      There are new applications that can make use of big data sets to explore various avenues of knowledge, and there are methods to refine healthcare delivery to be derived from these discoveries (crucial uses, noxerous applications). Some critically important ones include the application of public health, clinical use, medicine based on scientific evidence, and medical diagnosis, and verification, analysis, and patient monitoring. These are the various healthcare frameworks and healthcare storage systems that were briefly explained to explore applications of healthcare big data below.

      1.5.1 Electronic Health Records (EHRs)

      Electronic Health Records (EHRs) is by far the most prevalent use of big data in medicine. Each patient has his or her own digital record, which contains demographic information, medical history, allergies, and laboratory test results, among other things. Records are shared securely via information systems and are accessible to both public and private sector providers. Each record is composed of a single modifiable file, which enables doctors to make changes over time without incurring additional paperwork or risk of data replication.

      Kaiser Permanente is setting the standard in the United States and may serve as a model for the EU. They’ve fully implemented a system called Health Connect, which allows data to be shared across all of their locations and simplifies the use of EHRs. According to a McKinsey report on big data healthcare, the integrated system has improved cardiovascular disease outcomes and saved an estimated $1 billion through reduced office visits and lab tests.

      1.5.2 Telemedicine

      Television conferences, smartphones, and other wireless devices, and wearables being able to provide on-the-demand healthcare have recently brought about a major advancements in medical field using “Telemedicine”. A “Telemedicine” term is used to describe healthcare and treatment facility via electronic devices. Electronic or satellite technologies are used for the delivery of clinical services that are not close to where patients are located.

      Physicians use it for primary consultations, for early detection, for the development of disease, and for educating their colleagues, and as a tool for remote monitoring. While some uses, like robotic surgery, tele-surgery, allow them to operate at a quicker pace with high-resolution data feedback, these do not require the doctor and patient to be in the same location; others like ultrasonography allow for the use of wider applications like fast-molecular imaging/live motion, still apply the principle of real-time feedback.

      Clinicians deliver highly personalized treatment plans as well as helping to keep patients out of the hospital. Prior to this most healthcare organizations had used analytical techniques such as demographics, maps, databases, and graphical presentations in conjunction with predictive analytics to investigate issues related to healthcare delivery system growth and geographical issues. Additionally, by making early judgments on how the patient will respond to changes in his or her condition, this helps clinicians predict acute illnesses before they become worse.

      1.5.3 NoSQL Database

      Nowadays, much information is given to all databases, with the end result that it exists in multiple locations for purposes that are general in nature. There is no relationship between the tabular and non-relational schema in a NoSQL database. To those of you are not aware,
