Big Data has empowered organizations to inspect substantial volumes of structured and unstructured data. Big Data augments decision making, by delivering data and conclusions from the projected valuable information. Organizations are presently in a situation to consolidate their data with the acquired large data sets such as geospatial data. Client sentiments can be observed and changes in client conclusions can be effectively distinguished through the scouring of online information.
Data is an asset and becomes a liability when you are drowning in it. If an organization does not know how to leverage the data properly the greatest resource can become a downside. One of the biggest challenges is to extract value from their information resources, make better decisions, improve operations and reduce risk. How do Organizations add context to the unstructured data to fuel better analytics and decision making? The challenges include capture, curation, storage, search, sharing, analysis, and visualization.
This blog post gives an overview of Big Data, the associated challenges and the possible solutions offered by us.
Critical Data Challenges

Managing Big Data Eco Framework requires dexterity in the midst of interruptions

The demand for instant data access, regardless of whether by mobile applications or back-end machine learning frameworks implies data management systems must be lithe.
Big data management systems also need to be viewed as delivery systems, and the data they deliver must be valid for the models to work. That requires data specialists to spend a significant portion of their time investigating raw data before sustaining it to machine learning algorithms. Thus, preparing the data for further processing often becomes as challenging as the actual analysis of the data itself.
Companies that use their big data ecosystem divert data lakes toward developing new strategies, products, and revenue streams; in the process, they smash their old business patterns.
Big Data poses profound difficulties for data integration best practices
Figure 3: Data Integration
Data consolidation framework needs more energy to deal with Big Data:
The growing adoption of stream processing devices puts heavy pressure on the IT team to rev up the data integration process to real-time speeds. Without more extensive integration capabilities, organizations cannot fulfill future requirements for big data analytics and real-time operations.
Data Synchronization and consistency:
In the conventional extract, transform and load approach to data integration, the greater part of the data is brought to a staging area and synchronized as the data sets are processed in preparation for loading into the target system. However, as the number of origination points expands and the speed at which data is produced and delivered increases, it turns out to be more challenging to deal with the synchronization process. Capabilities of ETL tools to handle structured and unstructured data and deliver those in real-time or near real-time becomes key.
Real-time big data analytics conveys change to data administration
Figure 4: Real-time Big Data Analytics
The state of data administration keeps on changing, frequently determined by companies' grip of real-time big data analytics. Data preparation was once a much simpler discussion, but data is no longer taking a one-way path ending in a data warehouse. Instead, it is a part of an ongoing real-time system.
The technologies are complex. The streaming analytics engines that act on predictions and make fast recommendations involve many moving parts, both in terms of data ingestion and processing. These moving parts incorporate messaging frameworks, data streaming, in-memory analytics and so on.
The underlying complexity in new component compounding makes data management a more uncertain endeavor. Wisely selecting and combining these components is a daunting task. Knowing where best to apply the technology is challenging, too
Big data architectures confront huge obstacles with technology consolidation
Hadoop and all the related technologies empower organizations to outline big data environments that meet their specific requirements. In any case, assembling everything is complex.
Finding and deploying the right big data technologies within the expanding Hadoop ecosystem is a lengthy process frequently measured in years unless corporate executives throw ample amounts of money and resources at projects to speed them up. Missteps are common, and one company's architectural structure won't really mean different associations, even in a similar industry.
There is no easy-to-apply technology formula to follow. "Depending on the use case or user, different tools have to be chosen. With a host of options available in the technology stack across data ingestion, processing and presentation layer, choosing the most appropriate technology/tool itself demands a lot of deliberation. Scarcity of Subject Matter Experts (SME) in some of those niche areas poses another challenge.
In spite of building multifaceted big data architecture with more technology components, real data analysis in a timely manner still continues to be a major obstacle.
70% of Hadoop installations will fall short of their cost savings and revenue generation goals due to a combination of inadequate skills and technology integration difficulties.
Data Analytics Models are still inadequate
While many companies now use data analytics models to predict future customer behavior or real-time data to make business decisions rapidly, companies may sometimes be missing key moments to gather analytics data.
A key overlooked area from which to gather analytics data is the "in-between moments:" moments that might take place between key events that could relay important data.
For example, take the case of deliveries (packages) in transit "We can track a package on Amazon.com. What about the events that happen between those drop-off points? Places where we are noticing the damage that's occurring on a regular basis.
Ingesting data from devices such as SmartWatch devices or IoT devices can pose issues.
Data Visualization methods are problematic. We are dealing with data in new ways and in real time. But we tend to render our visualizations of data in old-fashioned ways: We use static graphs. We need a better visual paradigm for rendering time series information
How Data Challenges Affects Business
- Big Data makes data preparation steps more confounded to explore. One size fits all approach may not work in data preparation
- Companies need to ensure that the data they collect and analyze meets a specific level of quality and reliability for it to be trustworthy. Data capturing is an area that needs more focus
- Building big data architectures can be tedious and trying initially
- Deployment of big data systems stalls due to their complexity. Lack of big data skills when deploying a Hadoop environment affects usability and acts as a hindrance while leveraging the passive data sets
- Ingesting the data is the most challenging part of big data applications. Being able to pull growing amounts of data into the vendor’s big data architecture without any missteps is crucial for the success of a big data project
- Once data ingestion is complete, master data sorting to define different governance policies is another challenge
