List the advantages and disadvantages of DBMS over conventional file system?
DBMS can have several advantages - I am just giving a few of them...
1. Sharing of information
2. Real time transactional processing
3. Historical track record for auditing and control
4. A good disaster recovery plan may save a business from bankruptcy
Here are some disadvantages
1. DBMS subjects a business to a risk in the loss of critical data in its electronic format it can be more readily stolen without proper security
2. The cost of a DBMS can be prohibitive for small enterprises as they struggle with cost justification for making the investment in the infrastructure
3. Improper use of the DBMS can lead to incorrect decision making as people take for granted the data is accurate as presented.
4. Datas can be stolen by careless of the password security.

What are the advantages and disadvantages of hydel power?
Advantages:It helps in generating electricity for the people .Construction of dams helps in this process.Once dams are constructed electricity can be produced at a constant rate.Dams are designed to last many decades and can contribute the generation of electricity for many years.When in use the electricity produced by dams do not produce green house gases.this helps in pollution free environment.
Disadvantages:the release of water from dams during heavy rains can cause floods.Regulating and damming of rivers affect the natural flow of water causing the sediments to settle at the bottom resulting in rockier stream beds.It also fragment the rivers making it difficult for the aquatic fauna to migrate especially for spawning.Also construction of dams are highly expensive.
What are the advantages and disadvantages of fishing?
Advantages
One clear advantage of having a swimbladder is that little to no extra energy is necessary in order to remain stationary at a constant level of water. Only a slight control by use of the pectoral fins is required to balance out the propulsive force of water exiting the gills. Fish with no swimbladder on the other hand, such as mackerels, sharks, and rays must expend energy by constantly swimming in order to keep from sinking.
Another advantage of swimbladders is oxygen storage. Physoclists and physostomes alike may occasionally use the oxygen present within their bladder as an emergency backup in times of urgent need, although, this emergency store can only be of aid for a few minutes (Jones 1957).
Finally, swimbladders in some fish are known to increase hearing abilities. With the presence of inner ear- swimbladder connections, these fish have exhibited greater sensitivity to sound, however it is not yet clear whether there is also an increase in frequency selectivity (Coombs & Popper 1982a)
Disadvantages
One disadvantage of having a swimbladder is that neutral buoyancy can only be achieved at a small range of depths specific to certain fishes. If a fish swims below its buoyancy range, it will have to expend greater energy in the exercise of swimming in order to keep from sinking. On the other hand, if a fish swims above its upper buoyancy level, it becomes overly buoyant. Its swimbladder would expand to such a great capacity that the fish might be thrown out of control if it does not compensate for this increased buoyancy by vigorously swimming downward. The fuller the swimbladder gets, the more tipsy the fish is-- much like a large helium balloon. Therefore, many fish that do not have a swimbladder, such as the Atlantic mackerel, have greater depth flexibility and speed in moving through columns of water. A swimbladder would only serve as a constraint for these fish which are continuously active predators (Schmidt-Nielson 1997).
One other disadvantage of having a swimbladder is that oftentimes the bladder serves as an acoustical target which sounds can be bounced off of. This might enable predators to more easily locate the fish (Schaefer & Oliver 1998).
What are the advantages and disadvantages of galvanic skin response?
Acording to the video "Guide to GSR Biofeedback Techniques for the Natural ADHD Practitioner by Jason Alster , a GSR signal is labile in ADHD students and shows stress when an ADHD student is trying to sit still for a few minutes in a eyes open and an eyes closed condition. The GSR can be a measure of relaxed concentration in ADHD and test anxiety. Also , the GSR is taken from the skin and the skin is an organ that covers the whole body so it represents stress effects on the whole body. The advantage is that as a biofeedback signal it is easy to learn to control stress from it as a psycho physiological parameter
Advantages and disadvantages of apiculture?
Apart from the obvious answer that it gives us honey, which has well recognised nutritional and medicinal uses, bees are essential for most fruit. These are generally produced after bees pollinate the flowers and many fruit farmers rent hives during the blossoming season to ensure pollination.

What are the advantages and disadvantages of biochemist?
(1) Bioinformatics. Makes the rapid organization and analysis of biological data possible via computational techniques.
(2) Blue biotechnology. Marine and aquatic applications of biotechnology, used to improve cleanup of toxic spills, improve yields of fisheries, etc.
(3) Green biotechnology. Agricultural uses of biotechnology, such as the selection and domestication of plants via micropropagation, designing transgenic plants to grow under specific environmental conditions .Benefits are crops with better taste, texture, appearance, aroma, nutrition, yield, robustness in adverse environmental conditions, and resistance to herbs, fungi, and pests.
(4) Red biotechnology. Application of biotechnology to medicine, including the designing of organisms to produce antibiotics, and the engineering of genetic cures through genomic manipulation. Other areas:
(a) Drug production.
(b) Pharmacogenomics.
(c) Gene therapy.
(d) Genetic testing.
(e) Improved vaccines.
(f) Biopharmaceuticals.
(g) New medical therapies.
(h) Diagnostics.
(5) White biotechnology. Also known as industrial biotechnology. Exemplified by the designing of an organism to produce a useful chemical, the use of enzymes as industrial catalysts to either produce valuable chemicals or destroy hazardous/polluting chemicals, and the development of biotechnological processes that consume fewer resources than traditional processes used to produce industrial goods.
(4) Bioeconomics. Investment in applied biotechnologies to increase economic output
DISADVANTAGES:
(1) Loss of privacy via loss of medical and genetic information.
(2) Discrimination of people with genetic or medical anomalies.
(3) Cloning. It is considered to be unethical among various groups and can result in eugenic practises.
(4) Transformations of wild species into "super species" with resistance to pesticides, herbicides, or fungicides.
(5) Loss of biodiversity. Development of genetically modified crops or domestic livestock could reduce genetic variety among both domesticated and wild species.
(6) Harmful chemicals. Although biotechnology will generate many new and valuable chemicals, some chemicals with unknown or damaging environmental impacts are likely to be developed.

What are they advantages and disadvantages of a door hook?
Door hooks offer several advantages, including easy installation and the ability to maximize space by utilizing the back of doors for storage. They are versatile, accommodating various items like coats, bags, or towels. However, disadvantages include potential damage to the door surface from hanging heavy items and limited weight capacity, which may lead to the hook becoming unstable or falling off if overloaded. Additionally, door hooks can obstruct door movement or access to the door itself in some configurations.
