“Remember that every science is based upon an abstraction. An abstraction is taking a point of view or looking at things under a certain aspect or from a particular angle. All sciences are differentiated by their abstraction.” (Fulton Sheen) Graph and document databases (aka document stores), also demonstrate this principle. A few years, graph databases […]
What Is a Non-Relational Database?
A non-relational database describes a database with flexible storage and retrieval. While NoSQL databases form a subset of non-relational databases, non-relational databases also encompass any system that deals with high volumes of unstructured data at a lower cost. Many non-relational databases support SQL-compatible queries too. Data lakes and cloud databases can also be considered non-relational […]
Data Architects and Data Modelers: The SQL/NoSQL Debate is Dead
Karen Lopez says that when it comes to surviving as a Data Architect, “Hybrid is the future.” It’s no longer enough to speak only one language or stay attached to one set of technologies. According to Lopez, “purely relational (SQL) databases don’t exist any longer,” since most applications developed now use various types of database […]
SQL versus NoSQL Databases: A Review of Key Themes
Non-relational databases (aka NoSQL), in many different variations, have become a popular database model for handling Big Data. They use two novel concepts, making them different from earlier, “classical” database models. The concepts having so much impact are horizontal scaling, spreading out the storage and work, and eliminating the use of “Structured Query Language” (SQL) […]
A Review of Different Database Types: Relational versus Non-Relational
Relational databases are also called Relational Database Management Systems (RDBMS) or SQL databases. Historically, the most popular of these have been Microsoft SQL Server, Oracle Database, MySQL, and IBM DB2. The RDBMS’s are used mostly in large enterprise scenarios, with the exception of MySQL, which is also used to store data for Web applications. All […]
Data Modeling Lends a Hand to NoSQL Databases
Sectors such as banking, healthcare, and insurance are increasingly interested in NoSQL databases and Data Modeling for NoSQL. As they take their first or their next steps in the space, they want “to have the tools available to them that give credibility and legitimacy to the technology,” says Pascal Desmarets, Founder and CEO at Hackolade, […]
NoSQL Expects Another Big Year in 2016 and Beyond
by Angela Guess Ben Rossi recently reported in Information Age, “Allied Market Research predicts that the global NoSQL market will reach $4.2 billion by the end of 2020, with a growth rate of 35.1% compound annual growth rate (CAGR) from 2014 to 2020. The reason for this growth is that companies are looking for database […]
