The Key Elements of a Good Big Data Project

Before you learn about different big data projects, you should understand the criteria for evaluating them:

  • Quality Over Quantity

In the field of big data, it is a common tendency to prioritize quantity. However, quality should be a major focus while selecting data to analyze. The ultimate goal of big data analysis is nothing different from other analytical tasks. It involves driving important insights to fulfill business objectives and make major decisions.

So, it’s extremely crucial to collect data from the right sources for analysis. You can explore different resources before finding the absolute best for collecting data. Additionally, you will have to find the right algorithms for processing data and interpreting everything accurately.

  • Concentrate on Outcome and Impact

The purpose of big data projects is to meet several business objectives. So, your focus shouldn’t be on using more data or utilizing more tools to perform big data analysis. Instead, you should improve the impact of big data projects to allow organizations to develop better strategies.

  • Clean Code and Analysis

This aspect of big data projects will depend on your work mechanism as an individual or a team. It’s extremely vital to generate clean code. Therefore, your code should be formatted in the right way and contain comments in the necessary places.

A clean code makes it easy to proceed with big data projects. Even your colleagues will find it easier to proceed with the project at a later point when you might not be available.

While writing code for data analysis, rely on fair and goal-oriented methodologies. Emotions and biases can easily mess with the accuracy of your data analysis. So, you should stay away from these mistakes while writing code for big data projects.

What problems you might face in doing Big Data Projects

Big data is present in numerous industries. So you’ll find a wide variety of big data project topics to work on too.

Apart from the wide variety of project ideas, there are a bunch of challenges a big data analyst faces while working on such projects.

They are the following:

Limited Monitoring Solutions

You can face problems while monitoring real-time environments because there aren’t many solutions available for this purpose.

That’s why you should be familiar with the technologies you’ll need to use in big data analysis before you begin working on a project.

Timing Issues

A common problem among data analysis is of output latency during data virtualization. Most of these tools require high-level performance, which leads to these latency problems.

Due to the latency in output generation, timing issues arise with the virtualization of data.

The requirement of High-level Scripting

When working on big data analytics projects, you might encounter tools or problems which require higher-level scripting than you’re familiar with.

In that case, you should try to learn more about the problem and ask others about the same.

Data Privacy and Security

While working on the data available to you, you have to ensure that all the data remains secure and private.

Leakage of data can wreak havoc to your project as well as your work. Sometimes users leak data too, so you have to keep that in mind.

Knowledge Read: Big data jobs & Career planning

Unavailability of Tools

You can’t do end-to-end testing with just one tool. You should figure out which tools you will need to use to complete a specific project.

When you don’t have the right tool at a specific device, it can waste a lot of time and cause a lot of frustration.

That is why you should have the required tools before you start the project.

Too Big Datasets

You can come across a dataset which is too big for you to handle. Or, you might need to verify more data to complete the project as well.

Make sure that you update your data regularly to solve this problem. It’s also possible that your data has duplicates, so you should remove them, as well.

While working on big data projects, keep in mind the following points to solve these challenges:

  •         Use the right combination of hardware as well as software tools to make sure your work doesn’t get hampered later on due to the lack of the same.
  •         Check your data thoroughly and get rid of any duplicates.
  •         Follow Machine Learning approaches for better efficiency and results.
  •         What are the technologies you’ll need to use in Big Data Analytics Projects:

We recommend the following technologies for beginner-level big data projects:

  •         Open-source databases
  •         C++, Python
  •         Cloud solutions (such as Azure and AWS)
  •         SAS
  •         R (programming language)
  •         Tableau
  •         PHP and Javascript

Each of these technologies will help you with a different sector. For example, you will need to use cloud solutions for data storage and access.

On the other hand, you will need to use R for using data science tools. These are all the problems you need to face and fix when you work on big data project ideas. 

If you are not familiar with any of the technologies we mentioned above, you should learn about the same before working on a project. The more big data project ideas you try, the more experience you gain.

Otherwise, you’d be prone to making a lot of mistakes which you could’ve easily avoided.

Frequently Asked Questions (FAQs)

1How can one create and validate models for their projects?

To create a model, one needs to find a suitable dataset. Initially, data cleaning has to be done. This includes filling missing values, removing outliers, etc. Then, one needs to divide the dataset into two parts: the Training and the Testing dataset. The ratio of training to testing is preferably 80:20. Algorithms like Decision tree, Support Vector Machine (SVM), Linear and Logistic Regression, K- Nearest Neighbours, etc., can be applied. After training, testing is done using the testing dataset. The model's prediction is compared to the actual values, and finally, the accuracy is computed.

2What is the Decision tree algorithm?

A Decision tree is a classification algorithm. It is represented in the form of a tree. The partitioning attribute is selected using the information gain, gain ratio, and Gini index. At every node, there are two possibilities, i.e., it could belong to either of the classes. The attribute with the highest value of information gain, Gini index or gain ratio is chosen as the partitioning attribute. This process continues until we cannot split a node anymore. Sometimes, due to overfitting of the data, extensive branching might occur. In such cases, pre-pruning and post-pruning techniques are used to construct the tree optimally.

3What is Scripting?

Scripting is a process of automating the tasks that were previously done manually. Scripting languages are interpreter languages, i.e., they are executed line by line at run time. Scripts are run in an integrated environment called Shells. These include Unix, C shell, Korn shell, etc. Some examples of scripting languages are Bash, Node.js, Python, Perl, Ruby, and Javascript. Scripting is used in system administration, client, and server-side applications and for creating various extensions and plugins for the software. They are fast in terms of execution and are very easy to learn. They make web pages more interactive. Scripting is open-source and can be ported easily and shifted to various operating systems.

Scripting is a process of automating the tasks that were previously done manually. Scripting languages are interpreter languages, i.e., they are executed line by line at run time. Scripts are run in an integrated environment called Shells. These include Unix, C shell, Korn shell, etc. Some examples of scripting languages are Bash, Node.js, Python, Perl, Ruby, and Javascript. Scripting is used in system administration, client, and server-side applications and for creating various extensions and plugins for the software. They are fast in terms of execution and are very easy to learn. They make web pages more interactive. Scripting is open-source and can be ported easily and shifted to various operating systems.
