...Persevering Through The Odyssey Many themes are addressed in great literature, and “perseverance” is one that comes up again and again. Perseverance means to continue on through tough or harsh times despite the consequences to achieve success. The Odyssey is a great example of such literature in which this theme shows up multiple times. Written by the renowned poet Homer, The Odyssey tells the journey of Odysseus, King of Ithaca, who has defeated the Trojans and is returning back home ten years later where his family is waiting for him. Odysseus and his crew run into many challenges on the way back to Ithaca such as sea monsters and gods. Perseverance is a prevailing theme in The Odyssey shown throughout the epic especially in Odysseus and his wife Penelope. After being away from home for 20 years, Odysseus sets off to get back to...

...words still apply nowadays? Is it still important to do what’s right, no matter how large the opposition? Harper Lee, in her book, To Kill a Mockingbird, does a beautiful job of illustrating the importance of perseverance. Perseverance can be defined as a steadfastness in a specific course, while paying little heed to the trials and difficulties along the way. In the book, Atticus, Jem, and, Scout clearly demonstrate examples of perseverance. As the father of the Finch family, Atticus becomes the one setting the example of perseverance for his children, Jem and Scout. On page 75, Atticus explains to Scout, why he, as a lawyer, is defending a black man in court: “Scout, you aren’t old enough to understand some things yet, but there’s been some high talk around town to the effect that I shouldn’t do much about defending this man.” While this may not look very...

...Perseverance through tough times As you know, you are beaten down many times in life, but it is perseverance that will get you through those times in life. In the book The Call Of The Wild, Buck is beaten down many times along with the other dogs. With great perseverance Buck fights to get up, and steps up to fight for the people he cares for. In contrast to Buck, my mom had to have great perseverance to step up when my grandpa got sick. Although, Buck and my mother are very different, they were both badly beaten down but decided to get back up and step up to help their family and friends. No matter what type of species you are, we all have to go through many tough situations. But perseverance is what will get you through those situations, and will help you to thrive later on in life....

Even though the children play in the street it cause a safety risk to drivers that don’t speed or drive wreck less do to the children running in and out of the streets without looking for cars. The children are our future and they need to be protected. When a person is looking to buy a future home they want to see a nice neighborhood that looks respectable and not as if it’s a bad neighborhood. The appearance of a home in my belief can say a lot about the people who live there. Someone who takes care of their home for example pressure washing, not trash in yard, paint nicely applied. Also there are some resident that don’t have the money but the residents should do as much as they can. To give an example of this a resident in my neighborhood has fixed the garage door which is tilted half way closed and it’s not very appealing. The appearance of a residents lawn as well as home its self make a community. A yard or lawn care should at the minimum have the grass mowed. The plants should be not over grown or deceased.

...The poor people usually depends of this places for basic things like food or sleep,without that help some of them don`t survive winter. Most of these institutions exist thanks to donations made it by average people and not government assistance. Every day there is more people living on the streets and the help is simply not enough, even when these kind of institutions exist. The people which suffer of poverty even when we see them like a kind of dog in the street, they are human and they want a decent life like normal people. Is normal to say that those poor people are living on the streets by their own choice, but like I said before, that is ignorance. That people suffer a lot of things, even things that we never going to feel, for example the hungry . The sad of these situations is that most of these people is...

...Task 1 LO 1.1 All high-level programming languages support the concept of data types. A data type defines a set of values that a variable can store along with a set of operations. Data types are used to store various types of data which is managed by program. Data type attaches with variable to determine the number of bytes to be allocate to variable and valid operations which can be performed on that variable. Although C has several built-in data types, it is not a strongly typed language, as are Pascal and Ada. C supports various data types and here some common data type as character, integer and floating-point types. C defines five foundational data types as defined below: ▪ character ▪ integer ▪ floating-point ▪ double floating-point ▪ valueless These are declared as by char, int, float, double, and void, respectively. These types form the basis for some other types also. The extent and choice of these and data types may contrast amongst processor natures and compilers. However, in all belongings an object of type char is 1 byte. C stores character type inside as an integer. Each character has 8 bits so, we can have 256 different characters values (0-255). Character set is used to map between an integer value and a character. The size of an int is ordinarily the same as the word length of the implementation setting of the program. C has 3 classes of integer storage namely short int, int and long int. All of these data types...

...Write the following queries in SQL: Display a list of all instructors, showing their ID, name, and the number of sections that they have taught. Make sure to show the number of sections as 0 for instructors who have not taught any section. Your query should use an outer join, and should not use scalar subqueries. By using the university schema provided by db-book.com the following queries were done on the university database. The first query uses an outer join which works similar to the join operation but it keeps the rows that don’t match between the two tables that would be lost in a join operation. There are three forms of outer join: a) Left outer join displays the results from the left table even if the condition does not find any matching record in the right table. b) Right outer join will displays the results from the right table regardless if there is matching data in the left table. c) Full outer join will retain all rows from both tables, regardless if the data matches or not. The group by clause when used in a select statement collects data from multiple records and groups the results into one or more columns. The below is the query using left outer join operation: select ID, name, count(sec_id) as Number_of_sections from instructor natural left outer join teaches group by ID, name; The next query was written by using a scalar subquery without using an outer join operation. A scalar subquery is where the output of a subquery returns only...

...the rows that are in the first query but not the second by removing the rows that are only found in the second query. There are three primary SQL commands involved when implementing a Union, Intersection and difference relational operators. As you may know, SQL data manipulation commands are set-oriented which are involved in operating over entire sets of rows and columns in tables at once. The UNION, INTERSECT, and MINUS statements make sure these operations occur. Union, Intersect and Minus only work properly if relations are Union-Compatible, which is based on the names of the relation attributes that must be the same and their data types must be alike. Being compatible does not mean the data types have to be exactly the same. For example, both data types can be used to store numeric values such as NUMBER and SMALLINT as well as character (string) values such as VARCHAR and CHAR. An SQL IN statement can be used with where clause to list a set of matching records of a table. We can use SQL IN query with a NOT combination to filter out some records. We can link or collect data from two different tables using...

...Cursors A cursor is a variable that runs through the tuples of some relation. This relation can be a stored table, or it can be the answer to some query. By fetching into the cursor each tuple of the relation, we can write a program to read and process the value of each such tuple. If the relation is stored, we can also update or delete the tuple at the current cursor position. The example below illustrates a cursor loop. It uses our example relation T1(e,f) whose tuples are pairs of integers. The program will delete every tuple whose first component is less than the second, and insert the reverse tuple into T1. 1) DECLARE /* Output variables to hold the result of the query: */ 2) a T1.e%TYPE; 3) b T1.f%TYPE; /* Cursor declaration: */ 4) CURSOR T1Cursor IS 5) SELECT e, f 6) FROM T1 7) WHERE e < f 8) FOR UPDATE; 9) BEGIN 10) OPEN T1Cursor; 11) LOOP /* Retrieve each row of the result of the above query into PL/SQL variables: */ 12) FETCH T1Cursor INTO a, b; /* If there are no more rows to fetch, exit the loop: */ 13) EXIT WHEN T1Cursor%NOTFOUND; /* Delete the current tuple: */ 14) DELETE FROM T1 WHERE CURRENT OF T1Cursor; /* Insert the reverse tuple: */ 15) INSERT INTO T1 VALUES(b, a); 16) END LOOP; /* Free cursor used by the...
