Answer:
2. A data modelling project using a packaged data model REQUIRES A GREATER SKILL than a project not using a packaged data model.
Explanation:
1a. Review of universal models:
A data model is an abstract model that organizes elements of data and standardizes how they relate to one another and to the properties of real world entities. It has become the standard approach used towards designing databases.
A universal data model is a template data model that can be reused as a starting point or a building block to jump-start development of a data modelling project, industry specific model, logical data models.
1b. Discuss how these are being used more widely today.
*Universal data models helps professional reduce development time, improve consistency and standardization while achieving high quality models.
*Higher quality: just as architects consider blue prints before constructing a building, one should also consider data before building an app. A data model helps define the problem, enabling one to consider different approaches and choose best ones.
*By properly modelling and organization's data, the database designer can eliminate data redundancies (needless repetitions) which are a key source for inaccurate information and ineffective systems.
2. Greater and advanced skills are adequate and required when data modelling project is done using packaged data model while fewer skills are required when data modelling is done without packaged data model.
Answer: Falsifiability
Explanation: Falsifiability is the term that is defined as the evaluation of any particular hypothesis or theory to be proven wrong .This feature gives the access that the theory can be tested and have more accurate claims .
The ESP(Extrasensory perception) theory can also have feature of being falsifiable because the experiments and test lead to the issue that the negative effects of the theory are not certain which might occur due to simple observation of effects.
Answer:
The five factors to consider when trying to choose between a Solid State Drive, a Hard Disk Drive and, an External Hard Disk Drive are:
- Read/Write Speed
- Weight
- Power Consumption
- Cost
- Storage Capacity
- Solid State Drives (SSDs) are typically lighter in weight, faster and do not consume much power.
- Hard Disk Drives are relatively cheaper than SSDs. They also come with higher storage capacities but are more power-hungry and slower because they rely on mechanical/moving parts to read and write data.
- External HDDs are the cheapest of the three. They are not internal which is a major drawback given the additional weight. However, they come with gargantuan storage capacities that make you want to rethink having one. Besides, unlike SSDs, you can easily get them in computer accessories shops offline or online.

A casual game is a video game targeted at or used by casual gamers. Casual games may exhibit any type of gameplay or genre. They are typically distinguished by simple rules and by reduced demands on time and learned skill, in contrast to more complex hardcore games. They typically impose low production and distribution costs on the producer. Casual games are often played on a personal computer online in web browsers, but are also popular on game consoles and mobile phones.
Hope this helped. Have a great day! :D
