The most important distinction between the initial data analysis phase and the main analysis phase, is that during initial data analysis one refrains from any analysis that is aimed at answering the original research question. [109] The initial data analysis phase is guided by the following four questions: [110]
This six-phase process for thematic analysis is based on the work of Braun and Clarke and their reflexive approach to thematic analysis. [1] [46] [47] This six phase cyclical process involves going back and forth between phases of data analysis as needed until the researchers are satisfied with the final themes. [1]
Data thinking involves understanding that solutions require both data-driven and domain knowledge-driven rules. It evaluates whether data accurately represent real-life scenarios and improves data collection where necessary. The framework highlights the importance of preserving domain-specific meaning during data analysis.
Data Preparation; Modeling; Evaluation; Deployment; The sequence of the phases is not strict and moving back and forth between different phases is usually required. The arrows in the process diagram indicate the most important and frequent dependencies between phases. The outer circle in the diagram symbolizes the cyclic nature of data mining ...
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.

Data modeling during systems analysis: In systems analysis logical data models are created as part of the development of new databases. Data modeling is also used as a technique for detailing business requirements for specific databases .
A data collection plan is created and data are collected to establish the relative contribution of each root causes to the project metric (Y). This process is repeated until "valid" root causes can be identified. Within Six Sigma, often complex analysis tools are used. However, it is acceptable to use basic tools if these are appropriate.
Logical Data Modelling The process of identifying, modelling and documenting the data requirements of the system being designed. The result is a data model containing entities (things about which a business needs to record information), attributes (facts about the entities) and relationships (associations between the entities).
