It is important that no matter however minor or significant the application, it must be suited to the needs of the situation more than anything else. This is true in the case of the typical appointment scheduling API that is commonly found in most platforms that make use of some sort of scheduling.
Some aspects of scheduling make it important in most cases and when an application or a part of an application is being put to use to control this aspect of the program it is important the points that should concern the programmer at any time must be highlighted.
Using power optimally by the appointment scheduling API
The usual circumstances that the typical API is used in mobile platforms make this part of being as energy efficient as possible very important. With the mobile devices, it is a fact that there are differing modes of operation as compared to say a desktop. If the power settings are done just correct, it is possible to use the interface without loading the power circuit in any way. This provides for longer operational times as well.
An important factor with the power being used up is the heat generated on a typical day. The more efficient of APIs would provide as efficient a working as possible thus in a way leading to the least amount of heat generated in the system. This factor would be of significance in the warmer climates of the world when excess heat buildup could cause seizure of the device.
The role of the processor
No doubt any action performed by the applications in a device would take up a part of the performance of the processor. As long as the load on the processor is kept to the acceptable levels, there would really be no points as such for complaints.
In the past, the poor design quality of the interfaces as the API has brought about strained working of the processors. This is shown to create such an overload that the very performance of the device is compromised. When speaking of efficiency of working, the key role played by the processor along with the rest of the peripherals simply cannot be taken so lightly at any time.
The complete design that goes into the typical mobile device
When considered as a whole, mobile devices do take a fair amount of designing before it really does get to the point of utility. It thus becomes a major factor to have the API designed and integrated into the center of operations no matter however minor the role of communicating with the peripherals come to play.
The complete design not just looks at designing for the possibilities but for any of eventualities. It speaks volumes for the quality of design as well as the efforts that has been expended in the design to have interfaces that work no matter the load or operating environments.
