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.
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).
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.
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.

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 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.

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.
Even if one is given an hour to eat and another hour to fill the form, the simple fact is that your stomach will limit you to how much you can consume and which tastes you will distinctly remember. Some of the dishes and desserts will end up being judged on mere appearance.

It is stated that Siemens experiences challenges due to complexity of its operations, different geographical locations, different culture orientations, different economic variable like exchange rates, a varied business environments and other challenges which hinder its smooth operations of value creation for its shareholders.
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
