Blockchain is still considered new technology, best known for supporting cryptocurrencies such as Bitcoin and Ether. But blockchain can provide security for a variety of purposes, ranging from privacy controls on medical records to preventing vote tampering. Ultimately, blockchain is a secure, encrypted database of agreements. Blockchain serves as a bookkeeping/contract platform which is incorruptible […]
What Is Data Security?
Data security describes the implementation of policies and procedures to ensure people and things take the right actions with data and information assets, even in the presence of malicious inputs. The right actions mean controlling and enabling data activity by balancing needs from: Stakeholders: Protect personal information while allowing access for legitimate transactions agreed upon […]
What Is Cloud Computing?
Cloud computing provides computation, software, data access, and storage systems without requiring knowledge of the physical location and configuration needed. Cloud computing may be executed on or off premises, and has adopted virtualization, service-oriented architecture, and utility computing. Databases in the cloud may be implemented by: Virtual Machine Image: Users purchase virtual machine instances with […]
What Is a Graph Database?
Graph databases refers to a category of NoSQL databases that represent data whose relations are well represented as a set of nodes. These nodes have an undetermined number of connections and are evaluated through computer algorithms. Good graph database use cases include: Social relationships (nodes are people) Public transport links (nodes can be bus or […]
What Is a Document Database?
Document databases refers to a category of NoSQL that represents data in a tree structure, where paths or branches connect data values or leaves. Frequently, document stores use XML and JSON formats stores. There are few practical limits to the number of paths, fields, values, or types of data that can be added to specific […]
Data Governance vs. Blockchain
Data Governance is the hot topic in today’s security- and privacy-concerned digital ecosystem. Blockchain technology offers data-centered security to sensitive, transactional systems that require tamper-resistant, fully auditable tracking mechanisms. Thus, blockchain and Data Governance (DG) complement each other in many ways, while maintaining distinct operational philosophies and application turfs. Blockchain is today’s preferred technology for […]
Considerations for Ensuring High Availability of Applications and Data
Click to learn more about author Dave Bermingham. When you think about how best to ensure the high availability (HA) of your applications and data, you need to think about more than just the speed with which you can failover to a standby system if your database suddenly fails. Yes, you should be prepared for full failover […]
Case Study: Indiana University, Data Virtualization, and The Decision Support Initiative
“We can throw business intelligence tools at problems and we can have really smart technicians write code but if it’s not serving the needs of the business and actually answering questions that people need to know, then ultimately, our work is futile,” said Dan Young, Chief Data Architect at Indiana University (IU). Young said that […]
What Is a Key-Value Database?
Key-value databases, also called key-value stores, are often considered the simplest type of NoSQL databases. Each unique identifier is stored as a key with its associated value. The value can be any sort of byte array, data structure, or binary large object (BLOB), and works well for storing enormous amounts of data. Windows Explorer and […]
Blockchain Offers Internet of Things Data Quality and Data Security
The rapid advances of blockchain technology and the Internet of Things are changing how business on the internet gets done. Blockchain provides superior data security and Data Quality and, as a consequence, is changing the way people approach big data. This can be quite useful, as security remains a primary concern for Internet of Things […]
