The top 7 benefits of data integration

1. Cross-Department Collaboration 

Data integration enables real-time data access and sharing across departments. This facilitates data silos breakdown and cross-functional analysis.

2. Time Efficiency

The Preparation of data sets for data analytics and processing is a lengthy procedure. It usually involves data cleansing, conversion, and imports. Typically, the more sources are involved, the longer time it takes. 

Data integration automates data exports and allows customization. This enables faster data preparation and analysis. It also ensures data consistency across departments and software platforms. As a result, automated and unified views eliminate the need for manual data collection and boost productivity.

3. Error and Rework Reduction

Incomplete, inconsistent, invalid, and inaccurate data sets often stem from manual data collection. This is especially the case when they are executed from different locations and accounts.

Such compromised data typically causes:

  • incorrect reports
  • misleading analyses
  • overall misjudgment

Data integration solutions synchronize data to prevent reporting rework and guarantee it is precise and up-to-date. 

4. More Valuable Data 

Data centralization and standardization increases the value of business data over time. They help to identify potential problems and enforce upgrades in data accuracy and quality analysis.

5. 360-degree Customer View

7. Enables Digital Transformation

Data transformations are virtually impossible without data integration, as companies utilize centralized data to develop innovative products and services and personalize user experiences.

Data Integration Challenges

Data integration is a process that evolves as the company grows. Efficient data integration is essential for enhancing the customer experience or identifying business areas that require improvement.

There are several prominent data integration issues that businesses frequently face:

Several prominent data integration issues that businesses frequently face

Increasing Data Volumes 

The increasing size of valuable data vastly complicates data integration. Data storage is indeed affordable, and business analytics tools can handle large datasets. However, managing data quality and integration is the real challenge. This is especially the case when dealing with massive volumes. Joining huge datasets, performing large-scale aggregation and sorting operations, and implementing streamlined techniques hinder logistics and routine integration tasks.

Diverse Data Sources 

Data sources typically vary between standard structured datasets and streaming data, social media content, and ecosystem data from various stakeholders. Such variety makes data integration even more challenging.  

Typically, traditional data warehouses which are built on relational databases can handle some diversity. However, they lack the tools for data stream integration and unstructured data processing. Well-designed data lakes might handle various data types. It is also true that they can fall short of an SQL database in terms of data integrity and availability. 

Challenges of Data Quality 

Inaccurate, incomplete, and outdated data poses serious challenges. Indeed, soaring volumes and diverse sources invariably hinder maintaining consistency. This could result in decisions based on compromised or duplicate data.

That is why, to address potential issues during integration, technical teams must employ techniques including:

  • data validation
  • data cleansing
  • data deduplication
  • data normalization

These are common techniques used to to address potential issues during integration.

Data Security and Privacy Challenges

Data security and privacy necessitate detailed consideration of regulatory compliance, access controls, and encryption. Data transfers could cause unauthorized access and breaches. This in turn can lead to formidable commercial losses. Therefore, data masking techniques, establishing clear data ownership frameworks, and compliance with data protection regulations are critical.

Creating Data Warehouses and Data Lakes

Data warehouses aggregate disparate data sources such as:

  • structured data files
  • unstructured documents
  • streaming data sources
  • emails
  • weblogs
  • transaction logs
  • social media

They help BI to analyze sizeable datasets, query data autonomously, and improve consistency and quality.

While data warehouses are pivotal for informed decision-making and data fragmentation reduction, they also pose challenges. These include data loading, synchronization with external applications, and additional data wrangling process management. Nevertheless, improving data accessibility, integrity, and analytical capabilities would be impossible without them.

Companies utilize data lakes to consolidate and analyze sizeable datasets from various sources. They also use them to break down barriers between disparate data sources. This approach enables businesses to deepen their understanding of customers by gaining access to a unified and holistic perspective. This in turn results in informed decision-making and personalized experiences.

Solutions like Salesforce’s MuleSoft solve such data integration challenges by releasing new data warehouse connectors for their Anypoint Platform. These connectors simplify the integration and management of data.

They are designed for data warehouses like:

Snowflake, Amazon Redshift, Azure Data Lake Storage, Google BigQuery

MuleSoft simplifies data warehouse operations by leveraging these connectors to enhance efficiency and connectivity when dealing with diverse data sources.

ETL, ELT and Data Integration

Gathering the business intelligence necessary for growth takes time, effort, and the right data analytics tools. Many data reporting tools, however, lack the capacity to store all of the data from various analyses. You frequently end up with incomplete or inaccurate data, which can disrupt business operations and reduce revenue. 

That is why businesses utilize BI tools powered by:

  • ETL (Extract, Transform and Load) or
  • ELT (Extract, Load and Transform)

ETL and ELT are two common data integration strategies. ETL transforms data on a separate processing server before transferring it to the data warehouse. 

ELT, on the other hand, performs data transformations directly within the data warehouse. Unlike ETL, ELT enables direct raw data transfer to the data warehouse without staging processes.

The ETL and ELT data integration methods focus on data transfer between locations. Despite sharing the same primary goal, each method has unique characteristics and aligns with specific data requirements. The crucial difference is in the order of data transformation. ETL transforms data before loading it onto the server, whereas ELT transforms data afterward. 

As an older method, ETL is suitable for complex transformations of smaller data sets. It is also particularly beneficial for those who prioritize data security. Conversely, ELT is a more recent technology that enhances flexibility and is ideal for processing both structured and unstructured data.

The choice between ETL and ELT significantly impacts data storage, analysis, and processing. As the IT landscape shifts to the cloud, insufficient visibility into the internals of cloud databases and applications frequently makes ETL-based integration impossible to implement. When data integration occurs after the fact – typically in interday or intraday batches – the results of this BI data integration are likely to be outdated.

That is why the transition to cloud computing requires a shift from traditional ETL tools, which are inherently batch-oriented. The need for real-time updates, particularly in a globally dispersed workforce, has prompted organizations to seek modern solutions. MuleSoft’s Anypoint Platform emerges as a flexible solution, supporting real-time and batch API integration. Anypoint, unlike ETL tools, isolates applications and databases. It reduces dependencies and facilitates a continuous flow of up-to-date information.

The platform is perfect for:

  • fraud detection
