In the context of a relational database, a row—also called a record or tuple—represents a single, implicitly structured data item in a table. In simple terms, a database table can be thought of as consisting of rows and columns or fields. Each row in a table represents a set of related data, and every row in the table has the same structure.
For example, in a table that represents companies, each row would represent a single company. Columns might represent things like company name, company street address, whether the company is publicly held, its VAT number, etc.. In a table that represents the association of employees with departments, each row would associate one employee with one department.
In a less formal usage, e.g. for a database which is not formally relational, a record is equivalent to a row as described above, but is not usually referred to as a row.
The implicit structure of a row, and the meaning of the data values in a row, requires that the row be understood as providing a succession of data values, one in each column of the table. The row is then interpreted as a relvar composed of a set of tuples, with each tuple consisting of the two items: the name of the relevant column and the value this row provides for that column.
Row may refer to:
In computing, SAP HANA is an application server that includes an in-memory, column-oriented, relational database management system developed and marketed by SAP SE. SAP HANA was previously called "SAP High-Performance Analytic Appliance".
To create SAP HANA, SAP SE developed or acquired technologies, including TREX search engine (in-memory column-oriented search engine), P*TIME (in-memory OLTP database acquired by SAP in 2005), and MaxDB with its in-memory liveCache engine. In 2008, teams from SAP SE, working with Hasso Plattner Institute and Stanford University, demonstrated an application architecture for real-time analytics and aggregation, mentioned as "Hasso's New Architecture" in former SAP executive Vishal Sikka's blog. Before the name "HANA" stabilised, people referred to this product as "New Database".
The product provides Business Intelligence allowing real-time response. The first product shipped in late November 2010. By mid-2011, the technology had attracted interest but the experienced business customers still considered it "in early days". HANA support for SAP NetWeaver Business Warehouse was announced in September 2011 for availability by November.

Khalid Baheyeldin presents his session "HUGE? How To Deal with 381 Modules, 174GB Database and 200 Million Row Tables" at DrupalCamp Toronto 2012. Full session details: http://2012.drupalcamptoronto.org/sessions/huge-how-to-deal-with-381-modules-174gb-database-and-200-million-row-tables
In early 2011 Yammer set out to replace an 11 billion row PostgreSQL message delivery database with something a bit more scale-ready. They reached for several databases with which they were familiar, but none proved to be a fit for various reasons. Following in the footsteps of so few before them, they took the wheel of the SS Berkeley DB Java Edition and piloted it into the uncharted waters of horizontal scalability. In this talk, Ryan will cover Yammer's journey through log cleaner infested waters, being hijacked on the high seas by the BDB B-tree cache, and their eventual flotilla of a 45 node, 256 partition BDB cluster.
Hardware hacking for fun and profit We're used to creating systems that create millions of web pages, database rows and files every day. But our code rarely makes anything happen in the physical world beyond blinking a few lights in a server room somewhere. The good news is that the kind of electronic components that drive your washing machine, your car, your entertainment system and your giant killer robots are now ridiculously cheap, easy to program and come with convenient USB sockets. This talk will guide you through the basic of making your own devices using the Arduino platform and open-source software, and demonstrate a few reasons why you might want to do so.
MongoDB is an open source, document-oriented database designed with both scalability and developer agility in mind. Instead of storing your data in tables and rows as you would with a relational database, in MongoDB you store JSON-like documents with dynamic schemas. The goal of MongoDB is to bridge the gap between key-value stores (which are fast and scalable) and relational databases (which have rich functionality).

The goal of MongoDB is to bridge the gap between key-value stores (which are fast and scalable) and relational databases (which have rich functionality). Using BSON (binary JSON), developers can easily map to modern object-oriented languages without a complicated ORM layer. This new data model simplifies coding significantly, and also improves performance by grouping relevant data together internally.

From http://WindyCityRails.org September 12-13, 2013 When choosing the right data store for an application, developers face a trade-off between scalability and programmer-friendliness. With the release of version 3 of the Cassandra Query Language, Cassandra provides a uniquely attractive combination of both, exposing robust and intuitive data modeling capabilities while retaining the scalability and availability of a distributed, masterless data store. This talk will focus on practical data modeling and access in Cassandra using CQL3. We’ll cover nested data structures; different types of primary keys; and the many shapes your tables can take. There will be a particular focus on understanding the way Cassandra stores and accesses data under the hood, to better reason about designing sche...

Learn more about Apache Cassandra, a distributed NoSQL database optimized for scalability and high availability without compromising performance. Cassandra is perfect for managing large amounts of structured, semi-structured, and unstructured data across multiple data centers and the cloud. Gone are the days of complex SQL joins that don’t scale, Cassandra is a wide-row database that supports massive concurrent retrievals and writes. In this webinar, you'll learn: ✓ What is Cassandra, and what does it provide? What is it Not? ✓ How does Cassandra work? ✓ How is it able to massively scale? ✓ How do you use CQL? ✓ What are the tangible advantages you can expect for your own software needs? ✓ How to quickly get up and running with deploying to an IAAS provider like Amazon

SQL is the only ever successful, mainstream, and general-purpose 4GL (Fourth Generation Programming Language) and it is awesome! With modern cost based optimisation, relational databases like Oracle, SQL Server, PostgreSQL finally keep up to the promise of a powerful declarative programming model by adapting to ever changing productive data without performance penalties. Thousand-line-long, complex SQL statements can be run in far below a millisecond against billion-row strong tables if database developers know their ways around the SQL language - and the best news is: It's not that hard! In this talk, I'll show how the SQL database will constantly outperform any hand written data retrieval algorithm - or in other words - how SQL, being a logic language, is the best language for business...
