What is Data Hydration?
Data hydration is the process of importing data into an object. It’s also known as data lake hydration. When an object is waiting to be filled with data, it is “waiting for hydration.” If the object is filled with some data, but not all of it, it’s “partially hydrated.”
Data hydration can come from a data lake or any other data source. A data lake is a term used to describe a large and centralized repository that stores vast amounts of structured and unstructured data. It holds raw data in its original format, without predefined schemas or organization.
Data hydration is bigger than simple extraction and storage. It also includes the migration of data into the correct place and format so it can be used properly.
This is an important process, especially when you consider all of the unique sources of data these days, such as SaaS applications, on-premise business data, social media sites, and even IoT sensors like your thermostat or refrigerator.
Understanding Data Hydration
The lifecycle of data begins with its source. Data can originate from diverse channels such as databases, APIs, IoT devices, social media platforms, or other data lakes.
Once the data is collected, it undergoes a transformation process to ensure compatibility with the target system. This includes cleaning, formatting, and structuring the data to fit the desired structure or schema.
After the initial preparation, the data is ready to be imported into an object or system. This process may involve mapping the data to specific fields or attributes within the object, ensuring a proper fit for further processing and analysis.
Complete hydration occurs when the object is filled with the appropriate data, ready to be used for various purposes. This could involve feeding the object into a machine learning model, performing data analysis, generating reports, or supporting decision-making processes within an organization.
Methods and Mechanics of Data Hydration
Selecting and filling objects with the appropriate data involves a few key steps:
- Data Categorization: It is essential to categorize data based on its type, such as customer data, financial data, or product data. Categorization helps in identifying the relevant objects and determining where and how the data needs to be hydrated.
- Mapping Data: Once data is categorized, it needs to be mapped to the appropriate fields or attributes within the objects. This ensures that the data is properly aligned and can be effectively utilized for analysis and decision-making.
- Format Conversions: In some cases, data may need to be converted or transformed to fit the required format of the objects. This could involve converting data from one file type to another or reformatting data to match specific field requirements. Format conversions ensure compatibility and seamless integration.
How do you select and fill objects with relevant data? You have a few options. The method you choose depends on the specific requirements and context of the organization. Here are some common methods of data hydration and their applications:
1. Batch Processing
This method involves importing large volumes of data in batches. It is commonly used when dealing with historical data or when data updates are not required to be real-time. Batch processing is suitable for scenarios where data can be processed and imported periodically, such as nightly or weekly data updates.
2. Real-time Streaming
Real-time streaming is used when immediate data ingestion and hydration are necessary. It involves a continuous flow of data from streaming sources, such as sensors, social media feeds, or live transactions. This allows organizations to act upon data in real-time, enabling real-time analytics, monitoring, and decision-making.
3. Change Data Capture
Change Data Capture (CDC) focuses on capturing and processing only the changes made to data rather than the entire dataset. This method is beneficial when dealing with rapidly changing data, reducing processing time and resource requirements. CDC ensures that only the necessary changes are propagated to the objects, optimizing efficiency.
Cloud Migration and Big Data Processing
It’s no surprise that organizations are increasingly adopting cloud-based solutions for data storage and processing. This transition has implications for storing and processing big data on cloud platforms. Here are the key benefits.
- Cloud platforms provide the ability to scale resources up or down based on demand. This allows organizations to handle growing volumes of big data without the need for significant upfront investments in hardware and infrastructure.
- With cloud storage, organizations only pay for the resources they use. This is a big cost savings compared to maintaining on-premises data centers.
- Cloud storage lets anyone access data from anywhere, which facilitates seamless collaboration among teams and stakeholders.
However, there are considerations to keep in mind when using cloud storage for big data:
- You must ensure proper data encryption, access controls, and adhere to regulations to protect your data from unauthorized access.
- Transferring large volumes of big data to the cloud can be time-consuming and dependent on network bandwidth.
- It is crucial to have flexibility and consider multi-cloud or hybrid cloud strategies to avoid dependency on a single vendor and enable smooth migration or integration with other platforms or systems.
SaaS Applications and Data Hydration
SaaS applications often play a big role in data hydration strategies. They are valuable sources of data that can be integrated into the overall data ecosystem.
For instance, Salesforce (a CRM) stores customer data such as contact information, sales history, and interactions. By incorporating this data into the data hydration process, Salesforce users gain a comprehensive view of their customers. This data can be used to inform personalized marketing, sales, and support initiatives.
Similarly, applications like Workday (an HR management system) contain employee information, organizational hierarchies, and performance data. Integrating this data into the data hydration strategy ensures up-to-date employee records and facilitates workforce analysis and planning.
Moreover, SaaS applications have the ability to connect with social media and IoT sensors. Social media platforms generate vast amounts of user-generated content that can offer insights into consumer sentiments, trends, and brand perception.
IoT sensors provide data on machine performance, environmental conditions, customer behavior, and more. Integrating data from these sources enhances the overall data hydration process by incorporating real-time and contextual information.
Furthermore, you can benefit from merging off-premises (cloud-based) and on-premises (in-house) data sources. Combining these data sources can give you a holistic view of your data, which leads to good analysis, reporting, and decision-making.
You also get the benefits of both environments: Cloud platforms provide scalability, accessibility, and on-demand resources, while on-premises systems offer control, security, and compliance.
