Data for which an independent variable is time.
A data model is a collection of concepts that can be used to describe the structure of a database and provides the necessary means to achieve this abstraction whereas structure of a database means the data types,relationships and constraints that should hold on the data. Data model are divided into three different groups they are 1)object based logical model 2)record based logical models 3)physical models Types: Entity-Relationship (E-R) Data Model Object-Oriented Data Model Physical Data Model functional data model
-> A record based data model is used to specify the overall logical structure of the database.-> In this model the database consists of a no. of fixed formats of different types.-> Each record type defines a fixed no. of fields having a fixed length.-> There are 3 principle types of record based data model. They are :1. Hierarchical data model.2. Network data model.3. Relational data model.

You seem to have lost your text book so I am giving you a link where you can study data types, including derived data types.

Autoregression is a statistical model used to analyze time series data where a variable is regressed on its own past values. This model captures relationships between an observation and a number of lagged observations of the same variable. Autoregressive models are commonly used in forecasting and understanding patterns in sequential data.
Arima can be defined as an autoregressive integrated moving average (ARIMA) model is a generalization of an autoregressive moving average (ARMA) model. There models are fitted to time series data either to better understand the data and to predict future points in the series of forecasting

No known published data. The 583.10 was made in 1948 and probably 1949.
This forecasting model uses historical data to try to predict future events.
