Data Management, DefinedData management is the practice of collecting, keeping, and using data securely, efficiently, and cost-effectively. The goal of data management is to help people, organizations, and connected things optimize the use of data within the bounds of policy and regulation so that they can make decisions and take actions that maximize the benefit to the organization. A robust data management strategy is becoming more important than ever as organizations increasingly rely on intangible assets to create value. Show
Managing digital data in an organization involves a broad range of tasks, policies, procedures, and practices. The work of data management has a wide scope, covering factors such as how to:
A formal data management strategy addresses the activity of users and administrators, the capabilities of data management technologies, the demands of regulatory requirements, and the needs of the organization to obtain value from its data. Data Capital Is Business CapitalIn today’s digital economy, data is a kind of capital, an economic factor of production in digital goods and services. Just as an automaker can’t manufacture a new model if it lacks the necessary financial capital, it can’t make its cars autonomous if it lacks the data to feed the onboard algorithms. This new role for data has implications for competitive strategy as well as for the future of computing. Given this central and mission-critical role of data, strong management practices and a robust management system are essential for every organization, regardless of size or type. Data Management Systems TodayToday’s organizations need a data management solution that provides an efficient way to manage data across a diverse but unified data tier. Data management systems are built on data management platforms and can include databases, data lakes and data warehouses, big data management systems, data analytics, and more. All these components work together as a “data utility” to deliver the data management capabilities an organization needs for its apps, and the analytics and algorithms that use the data originated by those apps. Although current tools help database administrators (DBAs) automate many of the traditional management tasks, manual intervention is still often required because of the size and complexity of most database deployments. Whenever manual intervention is required, the chance for errors increases. Reducing the need for manual data management is a key objective of a new data management technology, the autonomous database. Data Management PlatformsThe most critical step for continuous delivery of software is continuous integration (CI). CI is a development practice where developers commit their code changes (usually small and incremental) to a centralized source repository, which kicks off a set of automated builds and tests. This repository allows developers to capture the bugs early and automatically before passing them on to production. Continuous Integration pipeline usually involves a series of steps, starting from code commit to performing basic automated linting/static analysis, capturing dependencies, and finally building the software and performing some basic unit tests before creating a build artifact. Source code management systems like Github, Gitlab, etc., offer webhooks integration to which CI tools like Jenkins can subscribe to start running automated builds and tests after each code check-in. A data management platform is the foundational system for collecting and analyzing large volumes of data across an organization. Commercial data platforms typically include software tools for management, developed by the database vendor or by third-party vendors. These data management solutions help IT teams and DBAs perform typical tasks such as:
The increasingly popular cloud database platforms allow businesses to scale up or down quickly and cost-effectively. Some are available as a service, allowing organizations to save even more. What is an Autonomous DatabaseBased in the cloud, an autonomous database uses artificial intelligence (AI) and machine learning to automate many data management tasks performed by DBAs, including managing database backups, security, and performance tuning. Also called a self-driving database, an autonomous database offers significant benefits for data management, including:
The increasingly popular cloud data platforms allow businesses to scale up or down quickly and cost-effectively. Some are available as a service, allowing organizations to save even more. Big Data Management SystemsIn some ways, big data is just what it sounds like—lots and lots of data. But big data also comes in a wider variety of forms than traditional data, and it’s collected at a high rate of speed. Think of all the data that comes in every day, or every minute, from a social media source such as Facebook. The amount, variety, and speed of that data are what make it so valuable to businesses, but they also make it very complex to manage. As more and more data is collected from sources as disparate as video cameras, social media, audio recordings, and Internet of Things (IoT) devices, big data management systems have emerged. These systems specialize in three general areas.
Companies are using big data to improve and accelerate product development, predictive maintenance, the customer experience, security, operational efficiency, and much more. As big data gets bigger, so will the opportunities. Data Management ChallengesMost of the challenges in data management today stem from the faster pace of business and the increasing proliferation of data. The ever-expanding variety, velocity, and volume of data available to organizations is pushing them to seek more-effective management tools to keep up. Some of the top challenges organizations face include the following:
Data Management Principles and Data PrivacyThe General Data Protection Regulation (GDPR) enacted by the European Union and implemented in May 2018 includes seven key principles for the management and processing of personal data. These principles include lawfulness, fairness, and transparency; purpose limitation; accuracy; storage limitation; integrity and confidentiality; and more. The GDPR and other laws that follow in its footsteps, such as the California Consumer Privacy Act (CCPA), are changing the face of data management. These requirements provide standardized data protection laws that give individuals control over their personal data and how it is used. In effect, it turns consumers into data stakeholders with real legal recourse when organizations fail to obtain informed consent at data capture, exercise poor control over data use or locality, or fail to comply with data erasure or portability requirements. Data Management Best PracticesAddressing data management challenges requires a comprehensive, well-thought-out set of best practices. Although specific best practices vary depending on the type of data involved and the industry, the following best practices address the major data management challenges organizations face today:
The Value of a Data Science EnvironmentData science is an interdisciplinary field that uses scientific methods, processes, algorithms, and systems to extract value from data. Data scientists combine a range of skills—including statistics, computer science, and business knowledge—to analyze data collected from the web, smartphones, customers, sensors, and other sources. Data Management EvolvesWith data’s new role as business capital, organizations are discovering what digital startups and disruptors already know: Data is a valuable asset for identifying trends, making decisions, and taking action before competitors. The new position of data in the value chain is leading organizations to actively seek better ways to derive value from this new capital.
