You use a data structure when you have data to store and:
A data model is a collection of concepts that can be used to describe the structure of a database. Data models can be broadly distinguished into 3 main categories- 1)high-level or conceptual data models (based on entities & relationships) It provides concepts that are close to the way many users perceive data. 2)lowlevel or physical data models It provides concepts that describe the details of how data is stored in the computer. These concepts are meant for computer specialist, not for typical end users. 3)representational or implementation data models (record-based,object-oriented) It provide concepts that can be understood by end users. These hide some details of data storage but can be implemented on a computer system directly.
You create your own data structure in database.
data structure is a way of storing data in a computer so that it can be used efficientlyan algorithm is a sequence of instructions, often used for calculation and data processing.Often a carefully chosen data structure will allow the most efficient algorithm to be used.

No, a data structure is a particular way of storing and organizing data in a computer so that it can be used efficiently.
The main data models in database management systems are relational, hierarchical, network, and object-oriented. Relational data model organizes data into tables with rows and columns. Hierarchical data model organizes data in a tree-like structure. Network data model allows each record to have multiple parent and child records. Object-oriented data model represents data as objects.

To arrange data in a particular manner.these manner or set of rules is defined in the data structure so that the data used in computer systems can properly used at necessary time.

Tries, it is a kind of tree data structure that can be used.
It is possible to explain data structure in layman's terms. Simply put, in computer terms, a data structure is a commonly used method of data organization.
