In an increasingly data-driven world, preparing your data for AI is the first and highest priority step in expertly harnessing its potential. Azure provides a comprehensive suite of tools designed to help businesses collect, transform, clean, and store data efficiently.

Before taking the plunge into developing AI applications, businesses must make sure that its data is well-organized and accurate, setting off on the right foot from the onset.

Why AI needs clean data to perform at its best

AI relies heavily on the quality of data it processes. Accurate data input is fundamental to producing meaningful results. The adage “Garbage in, garbage out” perfectly captures this principle. Ensuring data accuracy not only boosts the reliability of AI predictions but also enhances decision-making processes.

If your AI system is fed with inaccurate, outdated, or irrelevant data, it will inevitably generate poor outputs.

Many businesses are unaware of the wealth of data they already possess. This data, when properly utilized, can be transformative. Leveraging this data requires careful cleaning and organization.

To illustrate this, one advanced method of using company data involves Retrieval Augmented Generation (RAG), which combines company data with large language models (LLMs) to produce high-quality responses. RAG improves the specificity and relevance of AI outputs by grounding them in proprietary business information.

Managing data chaos for better AI performance

Data scattered across multiple systems and storage repositories poses a challenge for businesses. Fragmentation complicates efforts to ground or fine-tune LLMs, as varied data formats and locations make it difficult to obtain a cohesive dataset. Unifying this disparate data into a single, accessible format is an early priority for any AI initiative.

Data integration is the key to consolidating data from various sources, making it ready for consumption in AI models. Bringing together data from different systems and formats into a unified structure, businesses can streamline their data processing and analysis efforts.

Data integration is the key to AI-ready data

Data integration combines data from multiple sources, transforms it into a consistent format, and stores it in a centralized location. This makes it easier for AI models to access and analyze the data, ultimately leading to more accurate and actionable insights.

Through data integration, businesses are able to make sure that their AI systems operate on the most comprehensive and up-to-date information available – achieving higher-quality AI results and leveraging the full potential of company data.

4 Different paths to seamless data integration

Azure offers several methods to streamline the data integration process, each catering to different business needs. Understanding these methods can help businesses choose the right strategy to consolidate and utilize their data efficiently.

1. Old school ETL: The classic way to integrate data

ETL, or Extract Transform Load, is still a foundational method for data integration. This traditional process involves extracting data from various sources, transforming it to meet specific business or analytical needs, and then loading it into a centralized data warehouse.

ETL is well-suited for scenarios where data needs to be thoroughly cleaned and formatted before storage, making it immediately ready for analysis.

  • Extraction: Data is pulled from disparate sources such as databases, CRM systems, and external data feeds.
  • Transformation: The extracted data goes through various transformations, including cleaning, deduplication, and reformatting, improving both consistency and accuracy.
  • Loading: The transformed data is then loaded into a relational data warehouse where it can be queried and analyzed.

ETL processes are typically used in environments where data quality and format need to be controlled before analysis. It’s particularly beneficial for businesses with complex data transformation needs, requiring robust data governance and compliance measures.

2. ELT: The modern way to integrate data

ELT, or Extract Load Transform, offers a more contemporary method of data integration, reflecting more recent advancements in cloud storage and processing power.

Unlike ETL, ELT involves loading raw data directly into a data lake first, and then transforming it as needed – leveraging the scalability and flexibility of cloud-based storage solutions.

  • Extraction: Similar to ETL, data is extracted from various sources.
  • Loading: Raw data is loaded into a data lake, such as Azure Data Lake, without prior transformation.
  • Transformation: Data transformation takes place within the data lake using powerful processing engines like Azure Synapse Analytics or Databricks.

ELT is particularly beneficial for handling large volumes of data, as it permits transformations to be applied on demand.

Flexibility is ideal for businesses that need to perform complex, ad-hoc analyses or handle diverse data types without the constraints of pre-transformation.

Analyzing and preparing data before AI deployment

Before AI models can deliver valuable insights, the underlying data must go through rigorous analysis and preparation – an essential step to make sure that AI models function correctly and produce accurate outcomes.

Skipping or underestimating the data preparation phase can lead to AI systems that are unreliable or even counterproductive.

Inaccurate or poorly prepared data can lead to misinformed decisions and lost opportunities. For example, Gartner reports that poor data quality costs businesses an average of $15 million per year. Proper data analysis and preparation mitigate these risks by addressing errors and inconsistencies, thus laying a solid foundation for any AI initiative.

Discover and fix data issues during initial exploration

The initial exploration of data involves a detailed examination to identify and correct inconsistencies. This transforms raw data into a reliable resource that AI models can effectively use. Here are key areas to focus on during this phase:

  • Incorrectly formatted data: Data may come in a variety of formats that are incompatible with AI models. For example, date fields might use different formats (MM/DD/YYYY vs. DD/MM/YYYY), which can lead to misinterpretation. Standardizing these formats is a core priority.
  • Invalid data: Some data entries may be clearly incorrect, such as negative values for quantities that should only be positive. Identifying and filtering out these invalid entries is key to maintaining the integrity of the dataset.
  • Duplicate data: Duplicate entries can skew analysis and model training. For instance, having multiple records for the same transaction can distort sales metrics. Removing duplicates makes sure that each data point is unique and accurately represented.
  • Unnecessary columns: Data sets often contain columns that are irrelevant to the analysis. These extraneous columns clutter the data and complicate processing. Streamlining the dataset by removing unnecessary columns helps in focusing on the relevant information.
  • Creation of new columns: Sometimes, raw data needs to be optimized with additional calculated fields to make it more meaningful. For example, creating a column that calculates the time difference between order date and delivery date can provide insights into logistics efficiency.

Cleaning and preparing data improves the quality of the AI output and the overall efficiency of the data processing pipeline.

#McKinsey estimates that businesses that leverage data effectively are 23 times more likely to acquire customers and 19 times more likely to be profitable.
