The managerial grid model or managerial grid theory (1964) is a model, developed by Robert R. Blake and Jane Mouton, of leadership styles. [1] This model originally identified five different leadership styles based on the concern for people and the concern for production. The optimal leadership style in this model is based on Theory Y.
The research concluded that there is no single "best" style of leadership, and thus led to the creation of the situational leadership theory, which essentially argues that leaders should engage in a healthy dose of both task-oriented and relationship-oriented leadership fit for the situation, and the people being led.

A management style is the particular way managers go about accomplishing these objectives. It encompasses the way they make decisions, how they plan and organize work, and how they exercise authority. [2] Management styles varies by company, level of management, and even from person to person.
The four relational models are as follows: Communal sharing (CS) relationships are the most basic form of relationship where some bounded group of people are conceived as equivalent, undifferentiated and interchangeable such that distinct individual identities are disregarded and commonalities are emphasized, with intimate and kinship relations being prototypical examples of CS relationship. [2]
The leader–member exchange (LMX) theory is a relationship-based approach to leadership that focuses on the two-way relationship between leaders and followers. [1]The latest version (2016) of leader–member exchange theory of leadership development explains the growth of vertical dyadic workplace influence and team performance in terms of selection and self-selection of informal ...
The relational model (RM) is an approach to managing data using a structure and language consistent with first-order predicate logic, first described in 1969 by English computer scientist Edgar F. Codd, [1] [2] where all data are represented in terms of tuples, grouped into relations.
Behavioral styles theory: Blake and Mouton, in their managerial grid model, proposed five leadership styles based on two axes – concern for the task versus concern for people. They suggested that the ideal is the "team style", which balances concern for the task with concern for people.
The physical model is normally instantiated in the structural metadata of a database management system as relational database objects such as database tables, database indexes such as unique key indexes, and database constraints such as a foreign key constraint or a commonality constraint. The ER model is also normally used to design ...
