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:
Recommended is frame relay architecture with a local loop at each factory supporting the frame relay service connection to the network provider's POP
Explanation:
Frame Relay can be seen as WAN protocol that is said to often operate at both the physical and data layers link of the OSI reference model due to it high-performance and due to the fact that FRAME RELAY are as well use across Integrated Services Digital Network (ISDN) interfaces in which they are designed for cost-efficient data transmission in order to enable effective intermittent traffic between local area networks (LANs) and endpoints in wide area networks (WANs) which is why frame contains all the information necessary to route it to the correct destination.
Therefore type of BN and WAN architecture and WAN service i would recommend based on the above information is FRAME RELAY ARCHITECTURE with a local loop at each factory supporting the frame relay service connection to the network provider's POP.
Answer:
Arduino
Explanation:
<em>Arduino is a free and open-source electronics platform with simple hardware and software. Arduino boards can read inputs, turn on a sensor and transform it into an output, activate a motor, and turn on an LED. Sara may direct her board by sending a series of instructions to the board's microcontroller. To accomplish so, she used the Arduino programming language and the Arduino Software (IDE), both of which are founded on Processing.</em>
Answer:
the answer is A, B, C hope this helps.
