Field (computer science)

In computer science, data that has several parts, known as a record, can be divided into fields. Relational databases arrange data as sets of database records, also called rows. Each record consists of several fields; the fields of all records form the columns.

In object-oriented programming, field (also called data member or member variable) is the data encapsulated within a class or object. In the case of a regular field (also called instance variable), for each instance of the object there is an instance variable: for example, an Employee class has a Name field and there is one distinct name per employee. A static field (also called class variable) is one variable, which is shared by all instances.

Fixed length

Fields that contain a fixed number of bits are known as fixed length fields. A four byte field for example may contain a 31 bit binary integer plus a sign bit (32 bits in all). A 30 byte name field may contain a persons name typically padded with blanks at the end. The disadvantage of using fixed length fields is that some part of the field may be wasted but space is still required for the maximum length case. Also, where fields are omitted, padding for the missing fields is still required to maintain fixed start positions within a record for instance.

Field (geography)

In the context of spatial analysis, geographic information systems, and geographic information science, the term field has been adopted from physics, in which it denotes a quantity that can be theoretically assigned to any point of space, such as temperature or density. This use of field is synonymous with the spatially dependent variable that forms the foundation of geostatistics and crossbreeding between these disciplines is common. Both scalar and vector fields are found in geographic applications, although the former is more common. The simplest formal model for a field is the function, which yields a single value given a point in space (i.e., t = f(x, y, z) )

Even though the basic concept of a field came from physics, geographers have developed independent theories, data models, and analytical methods. One reason for this apparent disconnect is that "geographic fields" tend to have a different fundamental nature than physical fields; that is, they have patterns similar to gravity and magnetism, but are in reality very different. Common types of geographic fields include:

Joyà

Joyà is a 70 minute long, resident show at the Vidanta resort in the Riviera Maya, Mexico produced as a collaboration between 45 degrees and it's parent company Cirque du Soleil. It is Cirque's first resident show in Latin America. Joya premiered on November 8, 2014 inside the custom-built Joyà theatre, which seats 600 guests at capacity. The exterior design of the theatre was inspired by organic forms in a clearing surrounded by trees. The story, set in a naturalist's library which transforms into other exotic locations, follows the journey of a "rebellious young girl [who] is sent by her mischievous grandfather on a fantastical quest spanning generations".

Unlike other Cirque du Soleil productions, Joya is an "intimate theatrical and culinary experience" in that patrons have the option to enjoy the show along with a specially designed degustation menu at private tables around the stage, or simply have a glass of champagne with canapés on top of the show ticket. The show also incorporates smell into the acts, providing an all-around "feast for the senses".

Joy (7669 song)

Joy is a dance/R&B single by 7669. It was the second single released from her debut album 7669. The single charted on the Billboard R&B/Hip Hop Singles chart on May 14, 1994.
