Now that you have decided on a direction for your Term Project, you can now start with an initial design. Structural business rules and a conceptual entity-relationship diagram (ERD) are a useful tool to frame your initial design. You will be providing both in this Term Project iteration.

Let us review the basics of both of these items. The structural business rules will indicate the entities, relationships, optionalities, and pluralities of your Term Project design. For example, “A person may own many cars; a car is owned by one person” is an example of a structural business rule. A conceptual ERD is independent of the relational model, and therefore does not contain primary and foreign key constraints.

Make sure that all business rules are represented in the ERD, and that all entities and relationships present in the ERD are described by the business rules.

This Term Project iteration is not the final submission of the business rules or conceptual ERD for your Term Project. You have the opportunity to make modifications before the final Term Project submission at the end of the course.

...question Edgar Aerospace (EAI), a privately-owned manufacturer of aircraft components, has expanded rapidly over the last five years. Its wholly-owned subsidiary, PL Components Inc. (PL), has just received a government contract to manufacture certain electrical components. PL has experienced significant growth over the last two years and accounts for approximately 45% of EAI's consolidated inventories and sales. PL is located in Mexico, where labour is considerably cheaper than in Canada. To encourage capital investment in Mexico, the Mexican government has provided material forgivable grants to finance operations. A condition of the grant is that a minimum of 200 Mexican residents must be employed throughout the year. If this condition is not met, then the grants become due and payable on demand. While EAI has had a history of steady profits, its preliminary financial statements for the current year show a loss of $200,000. The loss is attributable to a material amount of research and development costs incurred by EAI in the current year. Your review of the statements also indicates that the company has changed its accounting policy for recognizing revenue from the completed contract basis to the percentage-of-completion basis. Your discussions with the controller indicate that, in addition to the controller, there is one full-time clerk in the accounting department. Given the growth of the company, the controller confides to you that the accounting for payables and......

...practice in health and social care Equality and rights in health and social care There are many reasons why people discriminate against in a health and social care setting: Culture People will discriminate because of a persons culture as they it might be different to their own culture and it might be unknown and strange to them. An example of this is in a care home as there are different people with different cultures will prefer different foods, they might not serve food that they like which means that they would not eat anything. Disability People will discriminate because of a person’s disability, as they are labelled as incapable and that they need a lot of help. An example of this of this is calling them names and making fun of their disability. This could happen in a health and social care setting as the care worker might not want to look after and give proper care to the disabled person as they need more care. Age People will discriminate because of their age. Old and young people are the most vulnerable in society. People will discriminate against people’s age as they are fragile and a priority in the public. For example, on a bus the first few rows are the priority so if you sit there and some one come on the bus that are the ‘priority’ you have to give your seat up. Social Class discrimination is when one or more people are not treated equally due to their poverty level. This type of discrimination often holds people back from realizing their......

...depending on network latency. However, reads on the secondaries will not be consistent with reads on the primary. Note that the secondaries are not idle as they must process all writes replicated from the primary. To increase read capacity in your operational system consider sharding. Secondary reads can be useful for analytics and ETL applications as this approach will isolate traffic from operational workloads. You may choose to read from secondaries if your application can tolerate eventual consistency. Avoid negation in queries. Like most database systems, MongoDB does not index the absence of values and negation conditions may require scanning all documents. If negation is the only condition and it is not selective (for example, querying an orders table where 99% of the orders are complete to identify those that have not been fulfilled), all records will need to be scanned. Use the most recent drivers from MongoDB. recent from MongoDB supports drivers for nearly a dozen languages. These drivers are engineered by the same team that maintains the database kernel. Drivers are updated more frequently than the database, typically every two months. Always use the most recent version of the drivers when possible. Install native extensions if available for your language. Join the MongoDB community mailing list to keep track of updates. Use covered queries when possible. Covered queries covered return results from the indexes directly without......

Mgt 5000 - Example Assignment 1

...GT500 Note to Student enrolled in MGT5000: S3 2011 Please note that this is just an example of an assignment based on the assessment in a previous semester. The task is therefore quite different to your assignment this semester. For example, this semester you have been asked to analyse a case study provided to you. Last semester students had to write their own scenario and analyse specific OB issues. The word count for each section also differs from the requirements this semester. However, the assignment will give you a good idea of the following: what critical analysis looks like, how to present your recommendations in table format and how your list of references should be presented (the Harvard Referencing system available on the USQ library site). Good luck!
