RDBMS Definition Stands for “Relational Database Management System.” An RDBMS is a DBMS designed specifically for relational databases. Therefore, RDBMSes are a subset of DBMSes. A relational database refers to a database that stores data in a structured format, using rows and columns. This makes it easy to locate and access specific values within the database. It is “relational” because the values within ..
OLAP Definition Stands for “Online Analytical Processing.” OLAP allows users to analyze database information from multiple database systems at one time. While relational databases are considered to be two-dimensional, OLAP data is multidimensional, meaning the information can be compared in many different ways. For example, a company might compare their computer sales in June with ..
Relational Database Definition A relational database is a database model that stores data in tables. The vast majority of databases used in modern applications are relational, so the terms “database” and “relational database” are often used synonymously. Likewise, most database management systems (DBMSes) are relational database management systems (RDBMSes). Other database models include flat file and hierarchical databases, though these ..
iPad Definition The iPad is a tablet computer developed by Apple. It is smaller than a typical laptop, but significantly larger than the average smartphone. The iPad does not include a keyboard or a trackpad, but instead has a touchscreen interface, which is used to control the device. Like the iPhone, the iPad runs Apple’s iOS operating system. This allows the iPad to run third-party apps, ..
Array Definition An array is a data structure that contains a group of elements. Typically these elements are all of the same data type, such as an integer or string. Arrays are commonly used in computer programs to organize data so that a related set of values can be easily sorted or searched. For example, a search engine may use an ..
OOP Definition Stands for “Object-Oriented Programming.” OOP (not Oops!) refers to a programming methodology based on objects, instead of just functions and procedures. These objects are organized into classes, which allow individual objects to be grouped together. Most modern programming languages including Java, C/C++, and PHP, are object-oriented languages, and many older programming languages now have object-oriented versions. ..
Null Definition When a variable has no value, it considered to be null. Having a null value is different than having a value of 0, since 0 is an actual value. However, when used in a boolean test, both null and zero result in a FALSE value. Programmers often use boolean tests to determine whether a variable ..
Router Definition This is a hardware device that routes data (hence the name) from a local area network (LAN) to another network connection. A router acts like a coin sorting machine, allowing only authorized machines to connect to other computer systems. Most routers also keep log files about the local network..
C# Definition C# (pronounced “C Sharp”) is a programming language developed by Microsoft. It was introduced in 2002 with version 1.0 of Microsoft’s .NET Framework. Since then, C# has gone through several revisions, corresponding with each .NET update. Today, it is one of the most popular programming languages for creating Windows programs and web applications. C# is a derivative of ..
