4. Return the card number, first name, last name, and average late fee of each customer. Name this column as "Fee".
5. Return the authors whose first names are shorter than all last names.
6. Return the first 10 borrowing which late fee is unknown.
How do I write these using Oracle SQL sub selects?
Answer:
To write these queries using Oracle SQL sub selects, the following syntax can be used:
1. Return the card number, first name, last name, and average late fee of each customer. Name this column as "Fee".
SELECT card_number, first_name, last_name, AVG(late_fee) AS "Fee"
FROM customers
GROUP BY card_number, first_name, last_name;
2. Return the authors whose first names are shorter than all last names.
SELECT *
FROM authors
WHERE LENGTH(first_name) < ALL (SELECT LENGTH(last_name) FROM authors);
3. Return the first 10 borrowing which late fee is unknown.
SELECT *
FROM borrowings
WHERE late_fee IS NULL
AND ROWNUM <= 10;
Explanation:
In these queries, sub selects are used to select specific data from a table and use it in the main query. For example, in the second query, a sub select is used to select the length of all last names from the authors table, and this data is then used in the main query to filter the authors whose first names are shorter than all last names. In the third query, a sub select is used to filter the borrowings with unknown late fees, and the main query is used to limit the result to the first 10 rows.

newaliases
sendmail
The newaliases command must be used to rebuild the aliases database after making changes to the /etc/aliases file.
What do you mean by newaliases ?In Linux, an utility called netstat is available for tracking and reporting data on network services. Actually, the Netstat command set is a collection of tools for reporting statistics on many parts of your network, such as which programs are using which ports.
The primary command used by this check to determine the CVM or host's NTP synchronization status is "ntpq -pn." To what remote peer or server is remote being synchronized? 127.127.
The alias database is rebuilt using the /etc/aliases file by the newaliases command. It must be launched each time this file is modified for the modifications to take effect. Running this command has the same effect as running sendmail with the -bi parameter.

explain software redundancy techniques
Answer:
Software redundancy techniques are methods used to ensure the reliability and availability of software systems. These techniques involve adding extra layers of functionality or data to a software system, so that if one component fails, the system can still function using the redundant component. This can improve the reliability and availability of the system, and reduce the likelihood of failures or disruptions.
Some examples of software redundancy techniques include:
Mirroring: This involves creating an exact copy of a system or data, and storing it on a separate server or location. If one system or data set fails, the other can be used as a backup.Redundant arrays of independent disks (RAID): This involves using multiple disk drives to store data, so that if one drive fails, the data can be reconstructed using the other drives.Load balancing: This involves distributing workloads across multiple servers or systems, so that if one system fails, the workload can be handled by the others.Overall, software redundancy techniques are an important way to improve the reliability and availability of software systems, and to reduce the impact of failures or disruptions on the operation of the system.
