Big data plays a huge role in how companies in almost every industry make decisions, create products, and manage their operations. This article explains various big data analytics challenges with solutions useful for freshers. Explore our big data analytics course syllabus.
Big Data Analytics Challenges and Solutions
Big data initiatives may encounter several difficulties, such as:
Data Quality Challenge
Challenge: Big data may be inconsistent, erroneous, or incomplete, and it can originate from a variety of sources. Analyzing and using the data may become challenging as a result. It includes the following:
- Duplicate Data: Duplicate data is a common result of importing data from several sources.
- Inaccurate Data: Operational inefficiencies and poor decision-making might result from inaccurate data.
- Incomplete Data: Analysis that is flawed can be caused by incomplete data. Additionally, it may make daily tasks more difficult.
- Data Downtime: Data downtime is the term used to describe periods when the data is incomplete, incorrect, or inaccurate.
- Hidden Data: Only a portion of the data is used by most businesses; the remainder may be lost in data silos or disposed of in data graveyards.
- Data illiteracy: Organizational teams that lack data literacy will make erroneous assumptions about the quality of the data, no matter how hard they try.
Solutions: Among the solutions for challenges with data quality in big data are:
- Data Integration: Data integration can improve availability and completeness while decreasing redundancy and structural and semantic heterogeneity.
- Data Governance: Responsible data democratization can be aided by data governance.

Data Security Challenge in Big Data
Challenge: A lack of security can result in identity theft, fraud, and data theft, making data security a major concern. Because it safeguards the availability, confidentiality, and integrity of data, big data security is crucial.
The following are some issues with big data security and their fixes:
- Data Encryption: This makes it more difficult for unauthorized individuals to access or change data by encrypting it into a code that can only be decrypted with a decryption key.
- Access Control: It restricts who has access to and what they can do with the data using user roles, permissions, and authentication.
Solutions: Some of the solutions for data security challenges are below:
- Anonymization and data masking: It replaces sensitive data with jumbled or fictitious information to protect it.
- Data Loss Prevention: Use technology, policy enforcement, and monitoring to stop data loss or leakage.
- Safe Preservation of Data: It protects data while it’s at rest via secure systems, backups, encryption, and disaster recovery strategies.
- Network Security: It safeguards information while it’s being transmitted.
- Monitoring and auditing: It monitors data-related activity to spot questionable behavior, find any security breaches, and enforce security regulations.
- Security Analytics: Advanced techniques are used in security analytics to find and fix security threats and anomalies.
- Policies for managing mobile devices: They establish stringent guidelines for employees’ personal device access to company data.
- Machine Learning: It increases the precision of fraud detection by using machine learning models to identify data irregularities.

Data Governance Challenge in Big Data
Challenge: Without a proper strategy for managing data, a data lake can become difficult to manage, leading to data quality, security, and privacy issues.
Big data governance may encounter numerous difficulties, such as:
- Data Volume: Data is growing in volume, pace, and variety.
- Stakeholder Support: To guarantee the successful implementation and upkeep of the data governance framework, it is imperative to secure the support and dedication of stakeholders at all levels.
- Data Lakes Governance: It may become challenging to monitor the contents of a data lake if it is not properly maintained and administered. Data quality, consistency, dependability, and accessibility issues may result from this.
Solution: Data governance necessitates extensive planning, monitoring, and decision-making. Data governance problems can be resolved with the aid of data governance tools or a GRC (Governance, Risk, and Management) solution.

Real-Time Analytics Challenge in Big Data
Challenge: Big data systems ought to be built with the ability to receive, process, and evaluate data as it is generated.
The following are some issues and fixes for big data real-time analytics:
- Scalability: Scalability is a major issue because big data is so vast. This problem can be resolved with the aid of cloud computing.
- Organizational Resistance: Applying data analytics frequently necessitates an unpleasant degree of change.
- Information security, computing, and visualization: The risk to information security rises with the volume of data.
Solution: Future trends can be predicted and real-time data can be explored effectively using big data. This may result in lower expenses and better treatment approaches.

Data Storage Challenge in Big Data
Challenge: Data storage problems, including server capacity, sharing, security, and file backup, might arise as an organization expands.
Big data storage may encounter numerous difficulties, such as:
- Scalability: Storage infrastructure must be adaptable and scalable because the amount of big data might grow rapidly.
- Security: The likelihood of data breaches and cyberattacks rises with the volume of data. Organizations must uphold data privacy, prevent illegal access to sensitive data, and adhere to data protection laws.
- Data integration: It can be challenging since big data might originate from a variety of sources and have a wide range of types and structures.
- Processing: Big data processing calls for certain tools and technology that can manage the data’s complexity, variety, and velocity.
- Traditional Storage System: Relational SQL databases may have trouble functioning well when they have a lot of data.
Solutions: Here are a few strategies to deal with these challenges:
- Utilizing infrastructures that are convergent and hyper-convergent
- Making use of software-defined storage
- Making use of deduplication, tiering, and compression
- Using methods like data masking and attribute-based encryption
- Putting access constraints in place
- Choosing to store data on a private cloud or a protected infrastructure instead of public cloud environments.

Skill Shortage Challenge in Big Data
For big data initiatives, it might be challenging to locate skilled tech personnel like data scientists, engineers, and analysts.
Challenge: For data professionals like data scientists, analysts, and engineers, the big data industry is experiencing a severe skills shortage. Organizations may find it challenging to create and retain productive big data teams as a result of this shortage.
The skills deficit is particularly difficult for the following reasons:
- The rapid evolution of the big data ecosystem: It is challenging to stay up to date with the rapid evolution of new tools, capabilities, and frameworks.
- Experience shortage: Many fresh graduates are capable of working with big data analytics, but there aren’t enough seasoned professionals with the proper blend of domain knowledge, business acumen, and technological skills.
- Organizations rushing to adopt big data analytics: Businesses are racing to implement big data analytics to remain ahead of the competition and acquire data-driven income streams.
Solutions: The skills deficit can be addressed in the following ways:
- Employ machine learning that is automated (AutoML): When analytics teams lack skilled staff, autoML can help them do more.
- Employ people from within When there aren’t many external applicants, hiring from within can be a viable option and save time and money.
- Invest in education and training: A skilled talent pool may be created by funding high-quality education, upskilling initiatives, and industry-academia partnerships.
