Overview of data architecture

Data architecture is the bridge between raw data and business needs. Imagine a disorganised pantry—if you randomly throw in tins of beans and bags of dry ingredients without a set organisational system, it’ll be incredibly difficult to find what you need for dinner. The same applies to data-driven organisations—disorganised, duplicate, and disconnected data prevents them from meeting their unique business requirements in a timely fashion.

How does data architecture work?

Data architecture works by creating a standard data environment for harmonised operations across the organisation. It takes a multifaceted approach to facilitating effective data management and evolves over time. Common methods include:

• Utilising data models: Data models represent the structure and relationships of data.

• Using storage solutions: Storage solutions are another way of keeping data organised and accessible.

• Enforcing security measures: Security measures keep data safe from breach, attack, or corruption.

• Enabling data governance: Data governance practices make data compliant with laws and regulations.

Together, these elements facilitate effective data management, supporting strategic decision-making and operational efficiency.

Robust data architecture should be flexible enough to accommodate specific business requirements. As new sources of data flood the market through emerging technology such as AI and Internet of Things (IoT) capabilities, data architecture makes data useful, organised, and retrievable.

When implemented correctly, data architecture helps companies by:

• Reducing data storage redundancies

• Improving data quality

• Increasing data cleansing and harmonisation opportunities

• Creating integration opportunities

• Reducing data silos

Types of data architecture and underlying components

Data architecture offers a high-level view of how different data management systems interact. Smaller data storage repositories, including data lake architecture, data warehouse architecture, and other data models fuel the analytical capabilities of different kinds of data architecture, including data fabrics and data mesh architecture.

Types of data models

There are three distinct types of data models:

1. Conceptual data models

Conceptual data models, sometimes called domain models, give businesses a big-picture view of what their data systems contain, how they’re organised, and what types of data rules are in place.

1. Logical data models

Logical data models are less abstract than conceptual data models. They provide a detailed view of data elements, how they interact with each other, and how they relate to different aspects of the business.

1. Physical data models

Physical data models are the most detailed types of data models. They outline the specifics of database implementation, including indexes, tables, and storage and performance specifications. They provide a detailed overview of how organisations secure, store, and access data.

Data architecture versus data modelling

The biggest difference between data architecture and data modelling is scale. Data modelling is part of data architecture—it’s the representation of data objects and their relationships. While data architecture provides the strategic framework, data modelling offers the tactical tools to implement that framework.

Types of data architecture

1. Data lake architecture

Data lake architecture, or simply a data lake, stores structured, semi-structured, and unstructured data at any scale, making it particularly useful for data scientists and data engineers. Data lake architecture enables organisations to safely collect data in its native format at speed—including cloud-based and on-premise data. It’s used to fuel emerging machine learning applications, AI capabilities, proof-of-concepts, and data backup and recovery operations.

1. Data warehouse architecture

Data warehouse architecture, also called a data warehouse, is a large storage repository that collects data from across the business. Data warehouse architecture keeps this disparate data in a singular, centralised location. It’s primarily used to help guide data management decisions and support business processes.

1. Data mart architecture

Data mart architecture, or data marts, is the smaller, more focused version of data warehouse architecture. It contains smaller subsets of data that are typically important to individual teams, users, or groups within an organisation, such as the sales department. The specialised data in these marts enable select teams or users to extract focused insights more quickly than a data warehouse. It's much more detailed than data lake architecture and data warehouse architecture.

1. Data fabric architecture

A data fabric is a combination of dedicated software solutions and data architecture that connect, manage, centralise, and govern data across different systems and applications. A data fabric helps organisations collect insights about their data and applies them to reduce silos and improve data maintenance measures. Data fabric architecture uses data from a variety of sources, including data lake architecture, data warehouse architecture, and other applications to give a detailed overview of how an organisation uses data. Data fabric is especially useful because it allows organisations to access their data no matter where it resides without having to constantly extract and rebuild it—all while keeping business context and logic intact. Unlike data storage systems, a data fabric streamlines all data in complex data architecture, making it useful for analytics, machine learning, and AI applications by securing, cleansing, enriching, and unifying it.

1. Data mesh architecture

Data mesh architecture, or a data mesh, organises data by domain in a decentralised location. Categorising data by domain—such as marketing, sales, or HR—empowers data owners within the business to make their own data-driven decisions and harvest insights for their business decisions. Data mesh architecture collects data from other decentralised sources, including data lake architecture and data warehouse architecture, and weaves it into a data fabric to provide detailed data insights and drive business agility.

Components of data architecture

Much like kitchen organisation, data architecture has several different components. Organisation isn’t just about physical bins—it’s also the thought processes and mental dedication needed to keep things tidy. Each aspect of data architecture plays a distinct role and contributes unique benefits that keep the architecture running smoothly. Key components of data architecture include:

• Data models: Data models are highly detailed, abstract representations of data objects and their interactions. They provide a layout of the organisation and structure of data and depict how data flows and dependencies work within an organisation’s data system. Data models are especially useful for designing databases, as they help ensure data integrity and consistency.

• Data integration: Data integration channels connect data from disparate sources in a singular, centralised view. Common data integration processes include ETL (extract, transform, load) operations, data synchronisation, and data migration. Effective integration creates a cohesive data environment that supports comprehensive analysis and reporting by connecting otherwise disjointed data silos.

• Data storage: Data storage includes databases, data warehouse architecture, and data lake architecture. Data storage solutions support both current and future data needs with better scalability, security, and reliability. Proper storage architecture improves data retrieval and management, enabling quick access to the correct information when needed.

• Data security: Data security measures are precautions organisations use to protect their data from unauthorised access, breaches, and corruption. Common data security measures include encryption, access controls, and regular audits. Establishing data security is critical for maintaining data integrity and compliance with regulatory requirements—protecting sensitive information from potential threats.

• Data governance: Data governance includes standard policies and procedures for managing data assets. It helps ensure data quality and enforces compliance with laws and regulations. A data governance framework defines roles and responsibilities, data standards, and accountability measures, which promote the effective and ethical use of data across an organisation.

Principles of data architecture

The principles of data architecture establish the core guidelines and best practices for managing data effectively across an organisation. These principles provide a foundation for creating a robust and scalable data environment, supporting both current and future business needs.

• Consistency: Well-structured data architecture ensures that data is uniform and standardised across the organisation. This involves using standardised data definitions and formats to facilitate easier integration and analysis.

• Scalability: Data architecture helps facilitate growth. As such, it’s prepared for increased data volume and additional data sources. By taking steps to plan for these changes, such as ensuring they have sufficient space for influxes of data or fast, flexible analytics software, organisations can keep their data architecture intact.

• Security: Security measures are crucial for keeping data architecture safe from unauthorised access, attacks, and breaches. By using common security measures, like the ones you may have on your phone or computer to protect yourself from viruses or identity theft, organisations can make sure their data is safe and their privacy is protected.

• Flexibility: By its very nature, data architecture is adaptable—it’s capable of accommodating changing technologies and business requirements at a moment’s notice. Instead of taking lots of time and readjustment to add new software, like AI capabilities or even a new emailing system, data architecture allows organisations to use new tools quickly and with minimal headaches.

• Availability: Data architecture makes data available for anyone who needs it, whenever they need it. Instead of restricting access to important information, such as sales data and revenue, organisations can make their data free to use for anyone within their ranks. This enhances timely and effective decision-making.

What are the benefits of data architecture?

When implemented correctly, data architecture provides businesses with a variety of benefits, including:

• Enhanced data lifecycle management: Modern data architecture helps businesses better manage their data over time. Since data quickly becomes outdated, fluid data architecture helps companies migrate data to slower, less expensive storage areas. Data architecture makes data more accessible for auditing without increasing the need for expensive data storage facilities.

• Improved data quality: Data architecture helps uphold data governance and security standards across the organisation. By storing data within high-quality data architecture, organisations quickly find the data they need and collect proper insights to inform business decisions.

• Reduced data redundancy: Duplicate data sometimes appears in disparate areas across an enterprise. Data duplication increases the risk of data inaccuracy and limits the potential for data integration. Well-structured data architecture empowers organisations to standardise data storage and reduce risky duplicates, enhancing data analytics processes.

• Minimised data silos: Disparate data storage zones often create data silos, which minimise an organisation’s ability to work at its greatest potential. Data architecture establishes flexible integration across data domains so different parts of the business can see each other’s data and communicate more effectively. This integration gives businesses a comprehensive view of important data points, such as expenses and revenues, which improves decision-making and maintains a single version of the truth.

What are the most common data architecture frameworks?

Data architecture frameworks are the basis of IT infrastructure and are critical for supporting a data-driven business strategy. Several frameworks are widely adopted to guide the implementation of data architecture within organisations. The most common types include:

• The Zachman Framework: This structured approach to data architecture organises enterprise data and processes by providing an overview of perspectives and abstractions. The framework covers everything from high-level contextual information to detailed operational specifics. It facilitates communication among stakeholders by offering a common language and methodology, enabling better alignment between IT systems and business objectives.

• TOGAF (The Open Group Architecture Framework): TOGAF is a high-level methodology for designing, planning, implementing, and governing data architecture. It focuses on aligning IT infrastructure with business objectives and creates a cohesive data environment. This helps organisations achieve their strategic goals through guided, structured data management.

• DAMA-DMBOK (Data Management Body of Knowledge): This framework offers comprehensive guidelines and best practices for data management. It serves as a useful reference for data professionals by covering various aspects of data architecture, including data governance, data quality, and data integration. The DAMA-DMBOK framework emphasises the importance of data management principles and practices by achieving consistent, high-quality data across an organisation.

The future of data architecture

Data architecture supports emerging data trends and recent technology, enabling organisations to pioneer modern technology and gain a competitive edge. Potential trends that data architecture can facilitate include:

• AI and machine learning analytics: AI and machine learning technology are revolutionising the data landscape with powerful predictive analytics, automation, and advanced data processing. These technologies improve data architecture by identifying patterns, making predictions, and automating routine tasks. All of these make intelligent data management systems more effective.

• Edge computing: Edge computing processes data closer to the user instead of relying on centralised data centres. When integrated into data architecture, it reduces overall latency and refines real-time data processing capabilities. This is crucial for applications requiring immediate insights, such as IoT devices and real-time analytics software.

• Blockchain: Blockchain technology creates a decentralised ledger system that boosts data security and integrity. By providing a transparent method of recording transactions, blockchain significantly improves the trustworthiness and reliability of data architecture.

• Data and analytics solutions: Data architecture enhances the performance of data and analytics solutions. Combined with the benefits of open data ecosystems, organisations with stable data architecture are more prepared to make agile business decisions within constantly evolving markets.
