A data field is a location for a predetermined type of data that — collectively with other data fields — describes the place it is stored. The most common example is a column in a data table that describes the row with which it intersects, and others include class variables in programming languages such as Java. A simple way to think about data fie...
The fundamental form of data is data tables. They consist of rows that we call records (or “tuples” if you’re fancy) and columns. The first column consists of unique IDs of the objects we are going to describe, and the columns contain information about it. NOTE: there is some dispute as to whether the first column should be considered a field or si...
Simple examples of data fields include weight, color, date, sales, averages, member ID, promotional code, status, file type, keyword, and rainfall. Any piece of information that can be used to describe an object, event, or idea can be a data field. That may sound silly, but it’s actually what makes data fields so flexible and so valuable — almost a...
In Excel, a data field is a column in any data table structure built with cells. It is easiest to identify when we’re using the Excel’s Data Table function (Insert > Tables > Table), but any column in a row-by-column table can be a data field — even a simple range.
The two dimensions of a data table consist, as we know, of rows and columns. Rows are referred to as recordsbecause they consist of one instance of the unique ID and each field. You’ve probably heard the word “record” used all your life without realizing that this is what it refers to. A record is nothing more than a complete row of data. Police re...
Database fields are not all made the same. In general, they fall into six types: (1) dates (2) numbers, (3) strings, (4) Unicode, (5) Binary, and (6) miscellaneous. In most cases, this is what you will encounter as a data analystsince the differnet subtypes tend to be complex and require knowledge of computer systems. However, for the sake of compl...
Sometimes we want to consolidate multiple data tables into one, and these tables concern the same unique IDs but are not labelled or normalized in the same way. Data field mapping is an activity that outlines how the fields from two or more starting tables will be consolidated into a new table. For example, consider the following two tables from a ...
In this article, we’ve only looked at data fields with intuitive names. In many cases, especially in scientific fields, codes or special jargon may be used as the title for a field. The problem with this is that, well, nobody else can understand it! Data dictionaries are the solution. A data dictionary describes a table’s columns based on common tr...
Data fields in programming languages are different from those in data tables because they often exist as a single entry of information that describes an object. Let’s go back to the definition of data field: a location for a predetermined type of data that — collectively with other data fields — describes the place it is stored. A data field in pro...
A common misconception, albeit a silly one, is mistaking “data field” for “field data.” Field data refers to information that is collected outside of a lab of office. For example, if I have to go survey people to collect data, we can say that data is collected “in the field.” Obviously, the field data will include rows and columns, so it includes d...
