Difference between Database and DBMS

The main difference between a database and a DBMS lies in their purpose and functionality. A database is a structured collection of data that is stored electronically and used for efficient data retrieval, while a DBMS (Database Management System) is a software tool that interacts with the database, enabling users to manage, organize, and manipulate data effectively.

In modern data-driven environments, a database acts as a digital warehouse that stores information, such as user records, sales data, and transaction logs. However, without a DBMS, accessing or modifying this data manually would be complex and error-prone.

A DBMS simplifies database administration through features like data security, backup, concurrency control, and query optimization. It also supports SQL commands for retrieving and updating records, ensuring real-time data access and consistent performance.

From Silos to Synergy: Real-time data sharing across eco-systems in real time

Despite advancements in data management technologies in recent years, the ability to get true potential of business data continues to evolve. From cumbersome batch processing to complex data formatting and transformations, sharing data across diverse systems and tech stacks is anything but easy or in real time.

This is one (of many!) reasons why we’re starting to see event-driven data automation tools revolutionize how businesses leverage data, especially when it comes to collaborating with strategic business partners and other external parties.

This article investigates common hurdles associated with traditional data sharing, highlighting the benefits of event-driven data automation for multi-party data exchange.

Data-sharing bottlenecks: Time to clear the path

Today’s data-driven economy demands agile data sharing, and relying solely on internal data is no longer sufficient. But while third-party data is essential for personalized experiences, fraud prevention, and lots more, current data-sharing mechanisms often fall short when it comes to exchanging information across diverse systems.

Historically, data exchange is primarily conducted through two methods:

Network data loads: Meticulously formatted data (e.g., CSV files) is transferred in batches between different systems. However, this static approach limits data updates to daily cycles at most, leading to information delays and stale business insights.

Online data platforms: While online platforms like CDPs, data lakes, and warehouses offer some potential for data sharing, the reality is that incompatible data stacks frequently create obstacles, requiring significant data formatting and transformation efforts.

Both methods present additional challenges as well. Batch processing is inflexible, making it difficult to accommodate real-time operational or market fluctuations. Transferring large datasets also carries significant security risks, potentially exposing sensitive information. Plus, incompatibility between data stacks can create silos across systems and companies, blocking business leaders from gaining a clear, comprehensive view of information for decision making.

These limitations translate to a host of real-world business challenges, such as:

Downstream disruption: Batch processing in industries such as financial services often leads to delays and lost opportunities. For example, payroll deposits arriving outside designated processing windows can disrupt downstream systems, causing customer frustration and potential financial hardship.

Increased operational costs: The complexities of data transformation and heightened security measures associated with traditional methods drive up costs. In manufacturing and retail, a lack of real-time data visibility exacerbates issues like inventory mismatches, inaccurate demand forecasts, and reactive replenishment strategies, all of which inflate operational expenses.

Poor customer experiences: Customers also face friction when businesses lack real-time data. For example, if a global airline doesn’t have access to up-to-date information, its customers may face limited flight or seating options or missed opportunities on using their miles for upgrades.

Heightened fraud risk: Across industries, delayed detection of fraudulent activities due to batch processing can also increase an organization’s exposure to financial losses.

A new paradigm: Secure, event-driven data sharing

Event-driven data automation is revolutionizing how businesses harness the power of data. End-to-end data automation platforms like Vendia act as a secure intermediary between mixed tech stacks (often with different database solutions), unlocking real-time data sharing.

This means that organizations can instantly analyze data, uncovering previously hidden opportunities and driving proactive strategies faster.

Here's how it breaks the mold:

Event-driven architecture: Data is immediately shared any time a predefined event occurs, eliminating the need for batch processing and ensuring information across business systems is always up-to-date.

Secure direct data transfer: Data moves directly between parties through secure connections, minimizing the attack surface and reducing the risk of exposure during transit.

Key Differences Between Data Governance and Data Management

In today’s data-driven world, organizations rely heavily on vast amounts of data to drive business decisions, enhance customer experiences, and improve operational efficiency. However, effectively handling data requires a strategic approach. Two essential concepts in this realm are Data Governance and Data Management. While they are closely related, they serve distinct purposes and involve different processes. In this blog, we will explore the key differences between Data Governance and Data Management and why both are critical for any data-centric organization.

What is Data Governance?

Data Governance refers to the framework of policies, procedures, and standards that ensure data quality, security, compliance, and accountability within an organization. It establishes rules for how data is created, stored, used, and maintained. The primary goal Data Governance of Data Governance is to ensure that data remains accurate, consistent, and protected throughout its lifecycle.

Key Aspects of Data Governance:

Data Ownership & Accountability: Assigning roles and responsibilities to individuals for managing data assets.

Data Policies & Compliance: Ensuring adherence to regulatory requirements such as GDPR, HIPAA, or CCPA.

Data Quality & Integrity: Maintaining high-quality data by defining validation rules and data accuracy standards.

Data Security & Privacy: Implementing measures to prevent unauthorized access and breaches.

Data Stewardship: Monitoring data usage and ensuring compliance with governance policies.

What is Data Management?

Data Management encompasses the processes, tools, and technologies used to collect, store, organize, and maintain data effectively. It involves the operational aspect of handling data across its lifecycle, ensuring accessibility, efficiency, and reliability.

Key Aspects of Data Management:

Data Collection & Integration: Gathering data from multiple sources and consolidating it.

Data Storage & Architecture: Storing data efficiently using databases, data warehouses, or cloud solutions.

Data Processing & Transformation: Cleaning, enriching, and preparing data for analytics.

Data Security & Backup: Implementing safeguards to protect data and ensure disaster recovery.

Data Analytics & Utilization: Using data for reporting, insights, and decision-making.

Key Differences Between Data Governance and Data Management

The primary purpose of Data Governance is to establish rules, policies, and standards for data usage, whereas Data Management focuses on the practical implementation and operation of data processes. While Data Governance ensures data integrity, compliance, and security, Data Management is responsible for collecting, processing, and maintaining data for operational use.

In terms of responsibility, Data Governance is typically overseen by data stewards, governance committees, and compliance teams. On the other hand, Data Management is managed by IT teams, database administrators, and data engineers who handle the day-to-day technical aspects of data.

Key components of Data Governance include policies, accountability, compliance, security, and stewardship, while Data Management involves databases, ETL (Extract, Transform, Load) processes, data warehouses, and analytics. The outcome of Data Governance is trusted, high-quality data that aligns with business rules, whereas Data Management ensures efficiently stored and accessible data for business operations.

Why Organizations Need Both Data Governance and Data Management

Organizations cannot rely on Data Management alone without Data Governance, as it may lead to inconsistent data, compliance risks, and security vulnerabilities. Conversely, Data Governance without Data Management lacks execution, making data policies ineffective. To maximize the value of data, businesses must integrate both strategies to achieve data accuracy, security, and usability.

Benefits of Implementing Both:

Improved Decision-Making: Ensures high-quality, well-managed data for reliable analytics.

Regulatory Compliance: Reduces legal and financial risks by enforcing data policies.

Operational Efficiency: Streamlines data handling processes, reducing redundancies and inefficiencies.

Enhanced Data Security: Protects sensitive information from breaches and unauthorized access.

Conclusion

Understanding the differences between Data Governance and Data Management is essential for organizations aiming to leverage data effectively. While Data Governance establishes the framework and policies for data integrity and compliance, Data Management ensures the proper execution of those policies through operational processes. Together, they create a robust data ecosystem that drives business success, mitigates risks, and ensures data reliability.

Organizations looking to thrive in the digital age must recognize that Data Governance and Data Management are not interchangeable but complementary. By aligning both strategies, businesses can harness the full potential of their data assets and maintain a competitive edge in an increasingly data-driven world.

Navigating the Data World: A Deep Dive into Architecture of Big Data Tools

In today’s digital world, where data has become an integral part of our daily lives. May it be our phone’s microphone, websites, mobile applications, social media, customer feedback, or terms & conditions – we consistently provide “yes” consents, so there is no denying that each individual's data is collected and further pushed to play a bigger role into the decision-making pipeline of the organizations.

This collected data is extracted from different sources, transformed to be used for analytical purposes, and loaded in another location for storage. There are several tools present in the market that could be used for data manipulation. In the next sections, we will delve into some of the top tools used in the market and dissect the information to understand the dynamics of this subject.

Architecture Overview

While researching for top tools, here are a few names that made it to the top of my list – Snowflake, Apache Kafka, Apache Airflow, Tableau, Databricks, Redshift, Bigquery, etc. Let’s dive into their architecture in the following sections:

Snowflake

There are several big data tools in the market serving warehousing purposes for storing structured data and acting as a central repository of preprocessed data for analytics and business intelligence. Snowflake is one of the warehouse solutions. What makes Snowflake different from other solutions is that it is a truly self-managed service, with no hardware requirements and it runs completely on cloud infrastructure making it a go-to for the new Cloud era. Snowflake uses virtual computing instances and a storage service for its computing needs. Understanding the tools' architecture will help us utilize it more efficiently so let’s have a detailed look at the following pointers:

Image credits: Snowflake

Now let’s understand what each layer is responsible for. The Cloud service layer deals with authentication and access control, security, infrastructure management, metadata, and optimizer manager. It is responsible for managing all these features throughout the tool. Query processing is the compute layer where the actual query computation happens and where the cloud compute resources are utilized. Database storage acts as a storage layer for storing the data. 

Considering the fact that there are a plethora of big data tools, we don’t shed significant light on the Apache toolkit, this won’t be justice done to their contribution. We all are familiar with Apache tools being widely used in the Data world, so moving on to our next tool Apache Kafka.

Apache Kafka

Apache Kafka deserves an article in itself due to its prominent usage in the industry. It is a distributed data streaming platform that is based on a publish-subscribe messaging system. Let’s check out Kafka components – Producer and Consumer. Producer is any system that produces messages or events in the form of data for further processing for example web-click data, producing orders in e-commerce, System Logs, etc. Next comes the consumer, consumer is any system that consumes data for example Real-time analytics dashboard, consuming orders in an inventory service, etc.

A broker is an intermediate entity that helps in message exchange between consumer and producer, further brokers have divisions as topic and partition. A topic is a common heading given to represent a similar type of data. There can be multiple topics in a cluster. Partition is part of a topic. Partition is data divided into small sub-parts inside the broker and every partition has an offset.

Another important element in Kafka is the ZooKeeper. A ZooKeeper acts as a cluster management system in Kafka. It is used to store information about the Kafka cluster and details of the consumers. It manages brokers by maintaining a list of consumers. Also, a ZooKeeper is responsible for choosing a leader for the partitions. If any changes like a broker die, new topics, etc., occur, the ZooKeeper sends notifications to Apache Kafka. Zookeeper has a master-slave that handles all the writes, and the rest of the servers are the followers who handle all the reads.

In recent versions of Kafka, it can be used and implemented without Zookeeper too. Furthermore, Apache introduced Kraft which allows Kafka to manage metadata internally without the need for Zookeeper using raft protocol.

Moving on to the next tool on our list, this is another very popular tool from the Apache toolkit, which we will discuss in the next section.

Apache Airflow

Airflow is a workflow management system that is used to author, schedule, orchestrate, and manage data pipelines and workflows. Airflow organizes your workflows as Directed Acyclic Graph (DAG) which contains individual pieces called tasks. The DAG specifies dependencies between task execution and task describing the actual action that needs to be performed in the task for example fetching data from source, transformations, etc.

Airflow has four main components scheduler, DAG file structure, metadata database, and web server. A scheduler is responsible for triggering the task and also submitting the tasks to the executor to run. A web server is a friendly user interface designed to monitor the workflows that let you trigger and debug the behavior of DAGs and tasks, then we have a DAG file structure that is read by the scheduler for extracting information about what task to execute and when to execute them. A metadata database is used to store the state of workflow and tasks. In summary, A workflow is an entire sequence of tasks and DAG with dependencies defined within airflow, a DAG is the actual data structure used to represent tasks. A task represents a single unit of DAG.

As we received brief insights into the top three prominent tools used by the data world, now let’s try to connect the dots and explore the Data story.

Connecting the dots 

To understand the data story, we will be taking the example of a use case implemented at Cubera. Cubera is a big data company based in the USA, India, and UAE. The company is creating a Datalake for data repository to be used for analytical purposes from zero-party data sources as directly from data owners. On an average 100 MB of data per day is sourced from various data sources such as mobile phones, browser extensions, host routers, location data both structured and unstructured, etc. Below is the architecture view of the use case.

Image credits: Cubera

A node js server is built to collect data streams and pass them to the s3 bucket for storage purposes hourly. While the airflow job is to collect data from the s3 bucket and load it further into Snowflake. However, the above architecture was not cost-efficient due to the following reasons:

AWS S3 storage cost (for each hour, typically 1 million files are stored).

Usage costs for ETL running in MWAA (AWS environment).

The managed instance of Apache Airflow (MWAA).

Snowflake warehouse cost.

The data is not real-time, being a drawback.

The risk of back-filling from a sync-point or a failure point in the Apache airflow job functioning.

The idea is to replace this expensive approach with the most suitable one, here we are replacing s3 as a storage option by constructing a data pipeline using Airflow through Kafka to directly dump data to Snowflake. The following is a newfound approach, as Kafka works on the consumer-producer model, snowflake works as a consumer here. The message gets queued on the Kafka topic from the sourcing server. The Kafka for Snowflake connector subscribes to one or more Kafka topics based on the configuration information provided via the Kafka configuration file.

Image credits: Cubera

With around 400 million profile data directly sourced from individual data owners from their personal to household devices as Zero-party data, 2nd Party data from various app partnerships, Cubera Data Lake is continually being refined.

Conclusion

With so many tools available in the market, choosing the right tool is a task. A lot of factors should be taken into consideration before making the right decision, these are some of the factors that will help you in the decision-making – Understanding the data characteristics like what is the volume of data, what type of data we are dealing with - such as structured, unstructured, etc. Anticipating the performance and scalability needs, budget, integration requirements, security, etc.

This is a tedious process and no single tool can fulfill all your data requirements but their desired functionalities can make you lean towards them. As noted earlier, in the above use case budget was a constraint so we moved from the s3 bucket to creating a data pipeline in Airflow. There is no wrong or right answer to which tool is best suited. If we ask the right questions, the tool should give you all the answers.

5. Real-Time Data Processing

SAP ERP: Due to its older technology, SAP ERP processes data in batches, which can result in delays in reporting and decision-making. Businesses might need to wait for data to be processed before gaining insights.

SAP S/4HANA: One of the standout features of S/4HANA is its ability to process data in real-time, thanks to the in-memory computing capabilities of SAP HANA. This means faster access to analytics, reporting, and data-driven insights.

6. Cost of Ownership

SAP ERP: The cost of ownership for SAP ERP can be higher due to the need for complex infrastructure, customization, and maintenance. As the system is based on older technology, upgrades and system changes can be costly and time-consuming.

SAP S/4HANA: While the initial investment for S/4HANA can be higher, it offers lower long-term maintenance costs. Its simplified architecture reduces the complexity of system updates and maintenance, and its real-time data processing and cloud compatibility can reduce infrastructure and operational costs over time.

7. Customization and Flexibility

SAP ERP: SAP ERP offers significant customization options, making it suitable for businesses with very specific requirements. However, these customizations often lead to higher implementation and maintenance costs.

SAP S/4HANA: S/4HANA offers flexibility through its modular structure, but with a simpler data model, it reduces the need for excessive customization. As businesses grow, they can more easily scale and adapt to new processes without the heavy customization required by traditional ERP systems.

Conclusion

In essence, SAP S/4HANA represents a modern, streamlined version of SAP ERP, offering superior performance, a more intuitive user interface, real-time data processing, and better flexibility. However, businesses that are already using SAP ERP and have extensive customizations may need to carefully plan their transition to SAP S/4HANA to ensure a smooth migration.

If you’re starting fresh or looking for a future-proof ERP solution, SAP S/4HANA is likely the best choice, as it supports emerging technologies, cloud solutions, and real-time analytics. On the other hand, companies with a well-established SAP ERP system may continue using it for the foreseeable future, though it may become more challenging to keep up with technological advancements.
