What Is Data Preparation?

 

Data preparation refers to the process of cleaning, standardizing and enriching raw data to make it ready for advanced analytics and data science use cases. Data analysts struggle to get the relevant data in place before they start analyzing the numbers. In fact, data scientists spend more than 80% of their time preparing the data they need before using it in various supervised and unsupervised machine learning models. It is called the 80/20 rule – with data analysts and data scientists spending 20% of their time on actual business analysis, while the rest is spent on finding, cleansing and organizing data. 

Data preparation solves this problem for data analysts and data scientists through an agile, iterative, collaborative and self-service approach. It flips the 80/20 rule to a company's advantage. It enables IT departments to offer self-service capabilities on their data assets while empowering data analysts to discover the right data asset, prepare the data, apply data quality rules, collaborate with others and deliver business value in significantly less time.

Why is data preparation important?

Today's enterprises generate enormous data every day through their customer interactions, business processes and various transactional activities. Based on these data proliferation trends, we see that everyone has access to the same computing power. Most of the organizations have access to the same set of machine learning algorithms, too. The only difference is the data and how enterprises use the data to make business decisions. The data that enterprises store indifferent places, be it on-prem or in the cloud, is messy and incomplete. Because of this, the employees in the organization cannot use this data to run their analytics and data science projects – and this is where data preparation becomes critical.

Data preparation for analytics

Data preparation is fast becoming a massive challenge as organizations embark on data and analytics initiatives in their digital transformation journey. In a typical data infrastructure, data is distributed across data lakes, data warehouses, databases, flat files, XML files, CSV files, audio files, etc. This massive proliferation of data makes it extremely difficult to find, clean, transform and share data safely and timely for driving advanced analytics use cases.

An AI-powered data preparation tool with an easy-to-use user interface can improve data analyst productivity by reducing the cycle time to get to analytics – saving time and money while boosting productivity.

Data preparation for machine learning

Hand coding and manually intensive approaches like using Excel spreadsheets for data preparation are time-consuming and redundant. Organizations are accelerating their machine learning initiatives to drive their digital transformation efforts. They have realized that machine learning and AI are critical for generating business value and making data-informed decisions.

Machine learning techniques have become pervasive across every industry (e.g., fraud analytics in the banking sector, customer engagement in retail, preventive maintenance in manufacturing, patient care in healthcare). They are used for almost all sorts of solutions using all data types – structured, semi-structured and unstructured data.

High-quality, trusted and governed data is key to the success of any machine learning initiative. Most machine learning projects fail due to untrusted data, making it garbage in and garbage out scenario. Due to these reasons, data preparation is essential for machine learning projects. But, the manual data preparation process becomes tedious due to the high volume and variety of data. Data scientists need high-quality training data to train the machine learning models. You need to infuse intelligence and automation into the data preparation process, provide the correct data set recommendations and automatically clean and transform the data for machine learning consumption. Data analysts and data scientists can improve their efficiency by focusing on building models rather than preparing data to train the model.

What is self-service data preparation?

Historically, data preparation was complex for analysts to do themselves and often limited to IT through a complex hand-coding process. On top of that, IT doesn't have the necessary business context of the data to prepare the data efficiently.

Informatica Enterprise Data Preparation

Informatica Enterprise Data Preparation allows data scientists, data analysts and citizen data integrators to do low-code/no-code, agile data preparation on a cloud data lake to drive self-service analytics and AI/ML use cases.It is part of the Informatica Intelligent Data Management Cloud designed for hybrid and multi-cloud environments.Here are six different ways Informatica Enterprise Data Preparation helps meet data needs:

  1. Data ingestion and profiling: Enterprise Data Preparation uses CLAIRE-powered machine learning to automate the profiling to identify data anomalies, outliers and frequency distribution; understand the shape and size of the data; and know what you want to do with it.
  2. Data catalog: An embedded data catalog helps data scientists and data analysts discover the data and understand the metadata by identifying the data lineage and how the data is related to other data.
  3. Data transformation: A low-code and no-code user interface help data analysts prepare data for analytics or data science consumption with no hand-coding.
  4. Data quality and data governance: Enterprise Data Preparation uses embedded data quality; and governance capabilities in the Intelligent Data Management Cloud, enabling data engineers and data analysts to apply data quality rules, enforcing governance and compliance policies on the prepared data models.
  5. Data enrichment: Enterprise Data Preparation formalizes third-party data such as customer geographical data, sensor data and customer segment data within the data model to drive customer 360 use cases.
  6. User collaboration and operationalization: Enterprise Data Preparation enables Data Ops teams to operate in an agile and iterative manner and provides theability to operationalize the models.

Industry use cases for data preparation

  • Healthcare: Data preparation can enable healthcare and pharma companies to speed research and development, accelerate drug discovery and deliver breakthrough therapies faster. An enterprise data preparation solution can support new use cases in data science, machine learning and IoT for improving patient care.
  • Insurance: Data preparation supports multiple use cases in the insurance sector like customer 360, risk management and underwriting.
  • Manufacturing: Data preparation helps drive various use cases in the manufacturing industry such as supply chain optimization, asset management and operational intelligence.
  • Public sector: Data preparation also supports use cases like cybersecurity, improving citizen experience and case management.
