Data Base Models The evolution of database models is as a result of the complexity of management needs of organizations. The need for improvement in the performance of database management system to enhance reliability and integrity has strategically redesigned database and changed the significance of their underlining models (Lima 84). This document attempts to uncover the similarities and differences of such models as the network model and hierarchical model.
The hierarchical model and network model are majorly differentiated in terms of data manipulation, data integrity, and data structure.
Data Structure
The hierarchical model stores data in a database that looks like a family tree with a single root and numerous branches or subdivisions. The record types are organised in the form of a rooted tree. However, in network model, multiple branches emanate from a single or more nodes (Lima 86). It can be likened to several trees sharing branches.
Data Manipulation
Consequently, the hierarchical model can be said to support one-one relationships and one-to-many relations in contrast to the network data model that supports many to many relationships. The hierarchical model supports a data structure whereby there is a parent-child relationship in contrast to the network model whereby a record can have many parents as well as many children.
Whereas the network model uses CODASYL the hierarchical model is not a provider of any independent, stand-alone query interface. The commonality among the models, the hierarchical model and network database model is that in both of them retrieve algorithms are complex and systematic (Lima 109).
Data Integrity
The hierarchical data model has an insertion a normally whereby one cannot retrieve information on a child who has no parent in contrast to the network model that has no anomalies. In addition, the network model is free from update anomalies as a result of a single occurrence in each set. The hierarchical data model, however, has multiple occurrences of child records, which causes inconsistency problems during the update operations.
In hierarchical model, data integrity is based on parent-child relationship and the deletion of parent results. In the deletion of child records, the network model is free from all the deletion anomalies because information is stored in a different table, which further enhances its efficiency.
Descriptionality
As the name suggests, ‘hierarchical’ meaning restrictive only to child-parent relationship, meaning even though a parent entity can have several child entity, a child can have only one parent.
Network Database Model
In the network database model, a child entity can have many parents and can be visualised as several inverted trees interconnected by branches contrary to the single inverted trees characterised by branches in the hierarchical model.
Folksonomy refers to a classification system derived from the methodology and practise of collaboratively, creating, and translating tags to categorize and annotate content. It is also referred to social tagging, social classification or collaborative tagging. The popularity of foxonomies on the web was in 2004 (Lima 103). Tagging a distinctive characteristic of web 2.0 allow users to find and classify information.
In conclusion, one of the most interesting depictions that I find most attractive is depiction of arc diagrams. Arc diagrams are capable of representing complex patterns of repetition in string data. I would recommend the book to anyone interested in learning visualizing of complex networks.

Technical complexity

...? Why is a technical complexity greatest with continuous-process technology? How does technical complexity affect organizational structure? There are three types of production technologies promulgated by Joan Woodward in the context of technical complexity, namely, small-batch and unit technology, large-batch and mass production technology, and continuous process technology (Jones, 2009). Technical complexity is greatest in continuous-process technology and the reason for this is that at this level, the products are manufactured at broadest level. Almost the entire conversion task, from input to output, is performed by machines under human supervision which make this process cost effective and highly technical at the same time... . The...

The complexity of Management

...?The complexity of management Introduction Complexity exists within an organisation because there is a usual process or activity that needs to be performed. There are varying situations involved on a daily basis and each department in an organisation has to handle them based on their specific tasks or roles. The ability of each department to perform its role brings forward specific actions that at some point may hinder other departments or the entire organisation to perform what is essential. However, the issue of what is essential for the organisation is what makes it more complex for each department to perform their tasks. In this paper, the proponent clearly illustrates situations that identify existing complexities within... an...

Despite their efforts to eliminate this by increasing measurable performance, reliance objectives, management of human resources, improved financial techniques, authority and accountability decentralization and resolving pathologies of principal-agent behavior success in their management has not yet been realized (Weber, 2008). All these attempts are aimed at improving the steering capacity in public management, policy makers and managers. Adoption of complex adaptive system approach in public management policy makers and...

Visualizing Nutrition

...? Visualizing Nutrition s Visualizing Nutrition Following the outbreak of various food borne diseases, members of the public warned of the impending risks of food related deaths. Food borne diseases are ailments caused by intake of food contaminated with pathogenic microorganisms. These diseases emanate from wrong food handling, preparation or preservation (David et al., 2005). The public must understand that proper hygiene prior to, during and after preparation of food can minimize exposure to food borne diseases. Frequent hand washing is among the most efficient protective measures against food borne diseases. Food safety involves analyzing food to ascertain that it is free of pathogens. As a safety...

Complexity and Contradiction in Architecture

...Order 184213 On The Phenomenon of "Both-And" in Architecture Of the Book Complexity and Contradiction in Architecture. New York, 1977 by Venturi, Robert. Prepared By DR. ZULFIQUAR AHMED ID: 10131 Abstract Architecture emerges out of fanatical and unrelenting debate. Architects can no longer afford to be intimidated by the puritanically moral language of orthodox Modern architecture. While Venturi is attributed as the father of postmodernism, he feels this movement perverted his ideas rather than embraced them. This text has the equal significance for Post-Modernism as Le Corbusier's Vers une Architecture, published in 1923, did for Modernism. It is, in other words, one of the pivots of modern architectural history. We know... that the...

'managing complexity'

...T306-TMA01 (2009/10) Questions a) I must confess that prior to reading the material, my understanding of ‘complexity’ and ‘managing complexity’ was a complete departure from the complexity dealt with in this unit. Now I know complexity is not that psychological problem of ‘inferiority complex’, though it is a complex problem of a sort. I now realize that I have experienced and I am still experiencing quite a number of problems that fit into the class of complex problems. These are problems I encounter in my place of work, home and other places of social interaction. They are problems are live with. They deal with me instead of me dealing with them because I have a very narrow understanding of them. Hence, they become increasingly... ...

Technical Complexity

...Technical Complexity Technical complexity refers to the degree of controlling, programming, and predictability (Daft, . In simpler terms, it infers the level of mechanization in a manufacturing process. High technical complexity infers that most of the work gets performed by machines while low technical complexity indicates that workers get more involved in the production process. Continuous-process technology offers an organization with an automated conversion process. This ensures that employees do not get involved in production. The employees’ functions in continuous-process technology get shifted to monitoring the machinery and managing exceptions like machine...

Interconnectedness & Complexity

...Interconnectedness and Complexity Interconnectedness concept is the ability of things to be enjoined or related in one way or another. In urban planning, interconnectedness applies to the connection between highways and how it affects the plan if done differently. Complexity is the factors of modeling and the application of complex systems put together as managed by the government. According to Levy (2013), the variables used to produce interconnectedness and complexity concepts normally determine the traffic flow experienced in an area. This implies that the direction or variable used in an urban plan influences the outcome experienced by the residents. Woodrow Wilson...
