Main approaches to database programming

List the three main approaches to database programming. What are the advantages and disadvantages of each approach?

Sample Solution

Main approaches to database programming

Database programming involves designing and maintaining a database for an application. Several techniques exist for including database interactions in application programs. The main approaches for database programming are the following: embedding database commands in a general-purpose programming language; using a library of database functions; and designing a brand-new language. In practice, the first two approaches are more common, since many applications are already written in general-purpose programming languages but require some data-base access. The third approach is more appropriate for applications that have intensive database interaction. One of the main problems with the first two approaches is impedance mismatch, which does not occur in the third approach.

ows the event manager to systematically and objectively analyse potential hazards throughout the event to any or all personnel on site and specific or generic stages throughout the event. Once hazards have been identified they are clearly able to be rated which provides a method of scaling risk, which allows for priorities to be set and actions to be taken or procedures to be put in place to negate or reduce the identified hazard or level of risk associated with it. The document also provides a record that can be shared with key stakeholders to demonstrate safe working practice and implementation of procedures to reduce risk. This is a key document required for the application of a license to allow the event to take place.

BC09 Fire Risk Assessment

Description:

This document provides an overview of the operational requirements in terms of fire safety. It details many perceived fire safety hazards across the venue through its various phases including build up; the event and de-rig which focuses on and is relevant to all visitors to the site including staff, contractors and the general public.

Discussion:

This document provides the venue, event manager and all other key stakeholders with a tool to analyse potential hazards to personnel from a fire safety point of view. It enables the level of perceived risk to be calculated alongside the likelihood of occurrence that can then be used to ascertain overall risk. This used effectively allows the event manager to formulate methods to reduce or remove the risk of injury from a potential hazard. Once a reduction method is in place the risk factor is recalculated providing an amended indicator. This action allows demonstration of ongoing work to mitigate risk to personal on site that is often focused upon by key stakeholders. This tool is highly useful in terms of providing a safe environment and complying with current relevant legislation.
