NoSQL A NoSQL (originally referring to non SQL or non relational) database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases.ometimes the data structures used by NoSQL databases are also viewed as more flexible than relational database tables. NoSQL databases are increasingly used in big data and real-time web applications. NoSQL systems are also sometimes called Not only SQL to emphasize that they may support SQL-like query languages.

Interquartile range In descriptive statistics, the interquartile range (IQR), also called the midspread or middle fifty, is a measure of statistical dispersion, being equal to the difference between the upper and lower quartiles, IQR = Q 3 − Q 1.or a symmetric distribution (where the median equals the midhinge, the average of the first and third quartiles), half the IQR equals the median absolute deviation (MAD). The median is the corresponding measure of central tendency.

- A database shard is a horizontal partition in a search engine or database. Each individual partition is known as shard or database shard. Each database shard is kept on a separate database server instance to help in spreading the load.

What is NoSQL, and why do you need it? The reality is that a relational database model may not be the best solution for all situations. The easiest way to think of NoSQL, is that of a database which does not adhering to the traditional relational database management system (RDMS) structure. Sometimes you will also see it revered to as 'not only SQL'.

Quantiles Quantiles Quantiles are points in a distribution that relate to the rank order of values in that distribution. For a sample, you can find any quantile by sorting the sample. The middle value of the sorted sample (middle quantile, 50th percentile) is known as the median. The limits are the minimum and maximum values. Any other locations between these points can be described in terms of centiles/percentiles.

database shard (sharding) A database shard (sharding) is the phrase used to describe a horizontal partition in a database or search engine. The idea behind sharding is to split data among multiple machines while ensuring that the data is always accessed from the correct place. Since sharding spreads the database across multiple machines, the database programmer specifies explicit sharding rules to determine which machines any piece of data will be stored on.

What Is SHA-1? SHA-1 is only one of the four algorithms in the Secure Hash Algorithm (SHA) family. Most were developed by the US National Security Agency (NSA) and published by the National Institute of Standards and Technology (NIST) .ne real-world example where SHA-1 may be used is when you're entering your password into a website's login page. Though it happens in the background without your knowledge, it may be the method a website uses to securely verify that your password is authentic.

What Is SHA-1? SHA-1 (short for Secure Hash Algorithm) is one of several cryptographic hash functions. SHA-1 is most often used to verify that a file has been unaltered. This is done by producing a checksum before the file has been transmitted, and then again once it reaches its destination.ne real-world example where SHA-1 may be used is when you're entering your password into a website's login page. Though it happens in the background without your knowledge, it may be the method a website uses to securely verify that your password is authentic.

What's the difference between sharding DB tables and partitioning them? To summarize - partitioning is a generic term that just means dividing your logical entities into different physical entities for performance, availability, or some other purpose. Horizontal partitioning, or sharding, is replicating the schema, and then dividing the data based on a shard key. Vertical partitioning involves dividing up the schema (and the data goes along for the ride).

Native Command Queuing (NCQ) Native Command Queuing (NCQ) Definition - What does Native Command Queuing (NCQ) mean? Native command queuing (NCQ) is a technology enabling SATA hard drives to accept more than one command at a time by optimizing the order in which read and write commands are executed. This increases the performance of the drive by limiting the number of drive head movements when multiple read/write requests are queued.

- In cryptography, SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function designed by the United States National Security Agency and is a U.S. Federal Information Processing Standard published by the United States NIST.HA-1 produces a 160- bit (20- byte) hash value known as a message digest. A SHA-1 hash value is typically rendered as a hexadecimal number, 40 digits long. SHA-1 is a member of the Secure Hash Algorithm family. The four SHA algorithms are structured differently and are named SHA-0, SHA-1, SHA-2, and SHA-3.

Pile integrity test Pile integrity testing using low strain tests such as the TDR (Transient Dynamic Response) method, is a rapid way of assessing the continuity and integrity of concrete piled foundations.hese included external methods such as excavation around the pile and internal or intrusive methods, such as core-drilling. While excavation may be effective in exposing flaws in the outer part of the pile, it is usually limited to a depth of a few meters.
