Data structures are used for storing groups of data together in a variety of different formats. This storing of multiple attributes of data together is referred to as an array. When coding an array, data is separated using commas and rows.

Types of Arrays include:
- One-Dimensional Array
The simplest form of an array in which the elements are stored in a linear sequence. Data can be accessed individually by specifying the index value of each element stored in the array.

- Two-Dimensional Array
A data structure that contains a collection of cells laid out in a two-dimensional grid or matrix, similar to a table with rows and columns. An index for both column and row are required for retrieving data.

- Array of Records
Stores records of related data such as in a database. As such, records are made up of multiple fields which can be used to reference and retrieve data. Records are stored in sequence, with each row representing an complete, individual record.
