Data Migration vs. Data Integration: Deciphering the Differences
With real-time data and intelligence at your disposal, you can optimize your business productivity and workflow. Organized and structured data play a vital role in helping you make informed decisions for the betterment of your organization. But have you ever wondered how you can combine such large volumes of data and utilize them for your benefit? Well, worry not because this guide has covered the two essential elements you need to know before performing data analysis.
To pilot a successful organization, you must have well-researched data compiled in one place. This might require you to integrate data from various sources or move data from one place to another. However, understanding when to use data integration and perform data migration can be confusing. So, in this article, you will quickly understand the distinction between data migration vs. data integration and when to execute them according to your business needs.
Data Integration: A Quick Overview
Data Integration involves compiling data and information from various sources into a unified database or data warehouse. It allows you to merge data from multiple sources to provide a consolidated view. The primary aim of data integration is to satisfy your evolving business requirements by offering a comprehensive set of data in one place.
It is implemented using various ways like ETL or ELT. You can use an automated system and streamline development by setting up a data integration tool.
Overall, data integration can be helpful for your organization in the short and long run. It facilitates consistency across all the databases, thus enabling you to make quick data-based decisions.
Data Migration: A Quick Overview
The process of moving data between formats and applications and across data storage systems is known as data migration. Many pre- and post-migration tasks involve planning, quality testing, results validation, and backup creation.
Before migration, data quality needs to be assessed to ensure a project’s successful execution without data loss. The likelihood of success for every data migration project depends on the type, volume, and quality of data being transferred and the technology that makes it possible.
Data Migration vs. Data Integration: Four Key Differences
Data integration and migration are integral to handling data but serve different purposes. Now that you have understood the basics of data integration and migration let’s look at some key differences.
Data Migration vs. Data Integration: Purpose
As data integration involves data consolidating from multiple sources into a single repository, its primary purpose is to provide a unified and comprehensive view of organizational data. This enables you to assess your data quickly and make impactful data-driven decisions.
On the other hand, data migration aims to move data to a new or existing system. It ensures that data is preserved, backed, and accessible in the new environment. This is performed to enable seamless continuity of your organizational operations.
Data Migration vs. Data Integration: Types
Data integration and migration are two distinct approaches in today’s data management, each employing different methodologies. You can employ them based on various factors like volume and nature of data, business requirements, and technologies. Here’s a comparison of their types:
Data integration can be implemented in the following ways:
- Real-Time Integration: In this integration method, the data is processed and transferred in real-time from source to destination. This allows you to access up-to-date information, enabling timely decisions and immediate responses to changing data conditions.
- Batch Integration: In this approach to data integration, data is processed and transferred in scheduled batches, typically at specific time intervals. The data in the pipeline is gathered over time and processed all at once. The time frame is called a batch interval, which is repeated periodically.
- ETL: In ETL, the data is collected from different sources, then transformed into a suitable format, and finally loaded into a central repository. ETL process ensures that accurate, complete, and reliable data is sent to the target system, thereby enhancing analysis capabilities.
- CDC: Change Data Capture technique identifies and captures changes made to the source database and replicates these changes to the target system to maintain data synchronization. This eliminates the need to transfer the entire dataset. This approach offers zero-downtime migrations and ensures consistent data replication. Thus, it helps save networking costs during data movement and expedites data integration.
- ELT: With ELT, the raw data is extracted from multiple source systems, then loaded into a specific storage, and finally transformed as needed for data analysis. This method has gained popularity in modern data architectures due to its flexibility in handling data modifications.
Comparatively, data migration can be performed in different ways, and sometimes, its types can be further combined in a single process. For instance, you can incorporate storage and cloud migration in a single data migration process.
- Storage Migration: In this, the data is transferred from one storage location to another. This can involve moving data between different storage technologies, such as from on-premises servers to cloud-based or from a physical to a cloud environment.
- Application Migration: It occurs when you want to change an application from one environment to another. This can involve transferring an application from one vendor to another, on-premises to the cloud, between different cloud providers, or upgrading to a newer version.
- Database Migration: This method can be employed when you migrate or upgrade your database from one database management system to another. However, it is crucial to maintain the consistency of data structures when performing the migration.
- Cloud Migration: It involves migrating data from an on-premise site to the cloud or moving between different cloud environments. It is usually preferable for migrating enormous data volumes.
Data Migration vs. Data Integration: Transformation
Data transformation is integral to data integration, as you often move raw data. This process involves converting the data into a format suitable for the target system. This may include tasks such as data cleansing, normalization, or enriching to ensure data is accurately represented. Transformation in data integration aims to combine disparate data sources and create a unified and consistent dataset for analysis and decision-making.
Data transformation in the data migration process also plays a crucial role but is slightly different. Unlike data integration, which aims to maintain ongoing synchronization between systems, data migration is a one-time process where you must move information from an existing system to a new one without jeopardizing the data quality. The transformation process may include data mapping, schema conversion, and data restructuring to ensure compatibility and integrity in the new environment.
Data Migration vs. Data Integration: Use Cases
Data integration consolidates data from multiple sources in a single unified database. The data integration process ensures data consolidation in a single repository and focuses on delivering valuable insights. For instance, if your data is located on a CRM application, online sales platforms, and multiple Google Sheets, data integration solutions can consolidate this data into a centralized repository. This integrated dataset lets you gain valuable insights into customer behavior, optimize inventory management, and personalize marketing campaigns. Data integration empowers value-based decisions by providing a holistic view of organizational data.
On the flip side, data migration is recommended for one-time data transfers or backups. Here are a few scenarios in which data migration can occur:
- Moving to a more secure data center or switching to centralized databases to achieve interoperability.
- When upgrading or swapping legacy software systems with modern systems to enable your business to fulfill performance standards and gain a competitive edge.
- Shifting to the cloud as it eliminates the cost of hosting the data in on-premises data centers.
- For data backups that will help disaster recovery.
