Explanation:
The reasons why indexed sequential search structure is better are:
1. In index sequential search any field of the records can be used as the key. This key field can be numerical or alphanumerical.
2. Since each record has its data block address, searching for a record in larger database is easy and quick. There is no extra effort to search records. But proper primary key has to be selected to make efficient.
3. This method gives flexibility of using any column as key field and index will be generated based on that. In addition to the primary key and its index, we can have index generated for other fields too. Hence searching becomes more efficient, if there is search based on columns other than primary key.
The reasons why 5 B-tree is better:
1.The B-tree Provides support for range of queries in an efficient manner and You can iterate over an ordered list of elements.
2. B-Tree algorithms are good for accessing pages (or blocks) of stored information which are then copied into main memory for processing. In the worst case, they are designed to do dynamic set operations in O(lg n) time because of their high "branching factor" (think hundreds or thousands of keys off of any node). It is this branching factor that makes B-Trees so efficient for block storage/retrieval, since a large branching factor greatly reduces the height of the tree and thus the number of disk accesses needed to find any key.
3. It is a generalization of a BST in that a node can have more than two children. These are self-balancing and hence the average and worst complexities is logarithmic. We opt for these when the data is too huge to fit in main memory. These structures are used in database indexing and help in faster operations on disk
the additional informations is we should first decide to choose which structure is suiatable for which algoritm in terms of space and time and then use the appropriate search algorithm.
Explanation:
so, what do you think ?
I am sure you have used a computer or a smart phone yourself.
how many clicks or taps do you want to do before you you get what you were looking for ?
hmmmm ?
as few a possible, right ?
ideally, of course, this is one (1) click or tap.

Explanation:
Australian regulations makes extremely difficult for the enterprises to move organizations sensitive data to the cloud which is storing outside the Australian network. These are all managed by the Office of Australian Information Commissioner(OAIC) which provides oversight on the data privacy regulations designed to govern the dissemination of the sensitive information.
One rule they applied under this is The Australian National Privacy Act 1988 which tells how the organizations collect, use, secure, store the information. The National Privacy Principles in the Act tells how organizations should use the people's personal information. The NPP has a rule that An organization must take the responsibility to hold the information without misuse or modified by unauthorized access. They require enterprises to put security service level agreements with the cloud service providers that define audit rights, data location, access rights when there is cross border disclosure of information.
In later time they introduced a new principle called The Privacy Amendment Act 2012. This principle gives set of new rules along with the changes in the many rules in the previous act and also this is having a set of new principles those are called Australian Privacy Principles (APP).
In this there is principle for cross border disclosure of personal information which is APP8. This rule regulates the disclosure or transfer of personal information by an agency or company to a different location outside the country.
Before disclosure the information outside they have to take responsible steps that the company outside the Australia must not breach the APP 's.
