Generally speaking, data analysis needs certain steps, mainly including four relatively independent and interrelated processes, namely, designing data analysis scheme, data collection, data processing and presentation, and data analysis.

Basic introduction

Data modeling is a process for defining and analyzing data and corresponding requirements for supporting information systems. Therefore, in the process of data modeling, the professional data modeling involved is closely related to the interests of enterprises and users' information systems.

From requirements to actual databases, there are three different types. As a conceptual data model, the data model used in information system is essentially a set of original standardized techniques for recording data requirements. Data is first used to discuss the initial requirements suitable for enterprises, and then it is transformed into a logical data model, which can be realized in the conceptual model of data structure in the database.
