DAO - data access object (in other words - object used to access data) A DAO is a class that locates data for you (it is mostly a finder, but it's commonly used to also store the data). The pattern doesn't restrict you to store data of the same type, thus you can easily have a DAO that locates/stores related objects.
Types of Components
- There are two types of components − 1. A central datastructure or data store or data repository, which is responsible for providing permanent data storage. It represents the current state. 2. A data accessoror a collection of independent components that operate on the central data store, perform computations, and might put back the results. Interactions or communication between t…

Model-Centric Approach
- The model-centric approachmeans developing experimental research to improve the ml model performance. This involves selecting the best model architecture and training process from a wide range of possibilities.
Data-Centric Approach
- In an age where data is at the core of every decision-making process, a data-centric company can better align its strategy with the interests of its stakeholders by using information generated from its operations. This way the result can be more accurate, organized, and transparent which can help an organization run more smoothly.
Data-Centric Approach vs Model-Centric Approach
- To data scientists and machine learning engineers, the model-centric approach may seem more pleasant. This is understandable since practitioners may use their knowledge to tackle a specific problem. On the other hand, no one wants to spend the entire day labeling data because it is considered a one-time job. However, in today’s machine learning, data is crucial, yet it’s often ov…

They may face challenges such as: 1. High-level customization is required Unlik…
Which One to Prioritize: Data Quantity Or Data Quality?
- Before going any further, I’d want to emphasize that more data does not automatically equal better data. Sure, a neural network can’t be trained with a few images, but the emphasis is now on quality rather than a number.
Where to Find Good datasets?
- Obtaining high-quality datasets is an important task. So, here are a few sites where you can get such datasets for free.
Conclusion
- In this article, we learned how a data-centric approach differs from a model-centric approach, and how to make your machine learning application more data-centric. We don’t have to limit ourselves in a single direction, code and data both play an important role in the AI journey. There is no hard and fast rule for choosing between model-centric and data-centric approaches but th…
