...We take furniture company of Try Star international .It has two branches one in Lahore and other in Karachi. Old system were centralized and we design a new system of database which is distributed i.e. the database of the Lahore campus is in Lahore and the database of karachi campus is in Karachi i.e a collection of multiple ,logically interrelated databases distributed over a computer network. DDBMS: A distributed database management system is defined as a software system that permits the management of the ddbs and makes the distribution transparent to the users. Why we use distributed database? In centralized system, all queries are handled by the main server and all loads are on the server but in distributed system, a separate server for each site exists. • In centralized system If centre goes down, everything is down. So you need to have offsite redundant servers. • In centralized system there is the single point of failure that can bring an entire company down in the event of a server crash but in distributed system if one server crashed down we get information from main server. Distributed Database design: The design of a distributed computer system involves making decisions on the placement of data and programs across the sites of the computer network .in the case of distributed DBMSs,the distribution of application invoves two things: • The distribution of the distributed DBMS softwares • the distribution of thr application of...

...Learning Path. This includes Sentence Skills, Punctuation, Mechanics and Spelling, and The Craft of Writing. When I selected the Mastered Module titled Sentence Skills, I selected Skills Check and took a short exam. This resulted in a suggestion to work on Fragments next. These skills directly apply my academic life because these are the very skills that are going to be evaluated by the instructors, which in turn will determine how successful I am in each class. While I may have the ability to analyze a situation, I won't be as successful in class if I am unable to correctly articulate that analysis using proper grammar, punctuation and sentence structure. The skills that I am learning in the Path Builder also relate directly to my professional life as a Paralegal, working for attorneys that rely on the written word to convey their legal arguments and points when defending their clients. I have to be able to construct clear and concise motions and pleadings, often times trying to convince a judge or prosecutor to see our point of view regarding very delicate topics. Most of my life, I have been naturally able to construct a proper sentence or write a grammatically correct paper, but I could never define a fragment or parallel sentence. I am excited about the positive affect this program is going to have on my writing skills! I was pleasantly surprised by the initial results of my Path Builder results because, while I have a naturally solid ability to write, I don't...

...group of attribute. The vertical partition is defined in three context memory level a centralized database and the most important is distributed database like placed data in different sites. In this paper we focus on distributed database. in which local transaction should be minimize. In this paper we use two phases the first approach is that we have no first knowledge and second is cost optimization. Fragmented may be no overlapping or overlapping. Summary Partitioning in database design is the process of assign object from the logical schema to the physical several objects. Vertical partition is the process of divide attribute into group (fragments) and assign to physical object. In vertical fragmentation we make maximum and all minimum possible fragments it mean that fragment may be overlap or non-overlap. So we make cluster of fragments that one overlap or no overlap but we use the both disjoint and no disjoint cases in partitioning. We use fragmentation to improve the performance of query optimization .according to distribution point of view the different approach is like hierarchy of memory partition. In this approach we used vertical partitioning in that way the attribute that are mostly accessed are placed inthat way the attributes that are highly access are placed in the fastest memory level.in the distribution environment we also use normally fragmentation but replica is also used . in the vertical fragmentation we use...

...When a file is stored in clusters that are not physically located next to each other on the platter, it is fragmented. Fragment can occur for various reasons, but most common cause is the modification of deletion of a file. To explain it generally is that there are three files. First one takes three spaces and the second and third takes two spaces. We remove the second one and replace with a five space file. Since all five can’t fit within the two spaces, we put two into the space and put the rest at the end. This is called fragmentation. Fragmentation can affect all files, including system files. As a result fragmentation will affect all window system. As a normal user, the hard drives will fragment over time and activities such as updates or installation and deletion of programs can cause major fragmentation. It will cause the performance to degrade over time. The different processes running in the background i.e. window explorer, all take an allotted amount of RAM to perform at optimum levels. More free RAM means that the essential processes that are running have more priority of the space and the CPU. When you begin to run your RAM to its limits, the essential processes and even the non-essential processes begin to lag due to the overtaxing of the CPU and RAM. Technically RAM does not have any influence on the processor performance, but it does have an influence on how much processes or technically instructions that processor can read. So a greater amount of RAM memory...

...Deforestation Jason Hennessee Axia College of University of Phoenix Deforestation “Dad! Dad! It’s opening day! Can we please go to the forest to watch the boats race?” Junior, age 10, was very excited about the idea of watching the boats race from the relative quiet and shade of one of the forests to border the river. “Sissy already has the car packed for the trip, and I think she even remembered to grab the charcoal this time!” Dean opened one eye. Seven in the morning was a bit early to leave for the boat races thirty minutes away when they started at nine. But, such was Junior’s excitement that Dean forced himself out of his bed earlier than he planned on. “Ok, son. Let’s check Renee’s packing and we’ll see about weather and conditions. Does Mom have her work finished yet?” Anne appeared framed in the bedroom door. “Yeah. I have some more reading to do, but I can do it at the site. The races are not my favorite thing, but you’ll need my help if the kids want to get wet. However, there is something I need to talk to you about. Junior, honey, please go make sure you have a cooler full of water and juice for us today.” Off like a shot, Junior dashed out of the room and Anne went in, closing the door behind her and lifting Dean’s laptop to the bed. “Dean, I think the forest is gone. Check this out.” Dean read the headlines and cutlines of the pictures and articles that Anne showed him. He shook his head as one by one they all told a devastating...

...Do threats to biodiversity pose the greatest challenge to humanity for the 21st century? Introduction: The term biodiversity refers to the variety of life on Earth at all its levels, from genes to ecosystems, and the ecological and evolutionary processes that sustain it. Biodiversity includes not only special we consider rare, threatened, or endangered, but every living thing even organisms we still know little about, such as microbes, fungi, and invertebrates. Biodiversity is important everywhere; species and habitats in your area as well as those in distant lands all play a role in maintaining healthy ecosystems. Biodiversity is important because it boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, a larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms. There are five main threats to biodiversity that I can cover later on in this report are: 1. Invasive alien species 2. Climate change 3. Nutrient loading 4. Water pollution 5. Loss of habitat 6. Overexploitation In this report my goal is to explain what biodiversity is in detail in depth and explain how important it is to the world. Also, to outline if and how these threats pose a threat to humanity in the 21st century. How important is biodiversity? Biodiversity is important for all species' survival. We need a variety of habitats for...

...and near. Now and then along life’s pathway.” There are lots of happiness to be discovered along the pathway of life. It is also saying that there is no way that anyone would be able have more than a couple fragments of happiness at the time. As it says in the poem, “But there are so many pieces, No one ever finds them all” Leonard is also saying that even if it feels like there is no happiness left in your life, you are wrong because happiness is scattered along your journey of life and no one can every find all of the fragments to complete the perfect, crystal ball. The ball symbolizes perfect happiness or Utopia. The poem states in stanza two, ”You might find a bit of beauty or honest share of wealth, While another just beside you, fathers honor, love, or wealth.” This explains that happiness is encountered in all different ways because you might get happiness from beauty and wealth while somebody gets happiness from honor, love, and health. Leonard is also saying that happiness is found in many different things in the world and at many different times and places. These are not the only ways of happiness. You can be happy from friends, family, having fun, or doing what you love. Leonard says in stanza three, ”Yet the wise on their journey, treasure every fragment clear.” This text explains that the smart people in life cherish their happiness because they know they are lucky to have it.

...Forests are the life root and the lungs of the world, it also supply us with oxygen, wood, biodiversity, the beauty of nature and many more. Humans rely on the forest even before our ancestors nomadic lifestyle ends and till this day humanity still depend on forests for their basic needs from raw materials such as lumber to its finished product that is furniture. Forests also prevents soil erosion, filters large amounts of air and water, and is the habitat for the wildlife that coexist with the floras in the forest. But lately, humanity has taken the forest for granted and never care about the consequences of their actions, cutting down trees and burning forests to make way for progress and development, removing chunks of forests for agricultural...

...Lemurs in Madagascar: 1. What are Madagascar’s biomes? Discuss the major features of at least one of these biomes. ~ The major features of these biomes is that they are wet, warm, and have high levels of biodiversity. The rainforest has four different layers. (Forest floor, understory layer, canopy layer and emergent layer) 2. What changes happening in Madagascar are posing challenges for lemurs? Give details about the sources, time scale, and types of changes. ~ The biggest change in Madagascar is the deforestation of the rain forest. It disrupts the eco-system, its home, and the food supply. 3. Which type of lemur are adapting to the changes? Which type of lemurs are not adapting well? Why? ~The bamboo lemur is the type of lemur that is not adapting very easy to the changes. The ring tailed lemur seems to be adapting well because it has the ability to adapt better. 4. What behavioral and physical traits are being favored in lemurs in the changing Madagascar environment? ~Some behavioral and physical traits that are being favored are their small bodies, long noses, and large eyes. 5. Why might lemurs not evolve to adapt to the changes in Madagascar? ~They won’t adapt because of the deforestation of the rainforest. Deforestation occurs at a rate of just under 1 percent a year. 16 species of lemurs have disappeared since humans arrived. They are threatened by distinction today. 6. Which biochemical cycles may be altered by anthropogenic activities on Madagascar, and...

...Dear Ms. Roberts, It is currently the summer of 2016 and I have just arrived in Brazil to watch the summer Olympics with my beloved, British boyfriend Harry Styles. Harry was invited to perform at the opening ceremonies here in Rio de Janeiro with his band, so I decided I would come with him and research the Tropical Rain Forests. The thing most different about rain forests compared to South Dakota is the fact that they are warm year-round. In fact, rain forests go through virtually no season changes. To say it simply, every season there is equivalent to a wet, hot summer. Tropical rainforests on average have around 100 inches of rain a year and the temperatures range from 40 degrees Fahrenheit to 100 degrees Fahrenheit. The amounts of animals that are located in the rainforests seem endless. One of my favorites, though, is the Brown-throated Three-toed Sloth. This sloth is unique because unlike many other species of animals, the male and females are almost exactly proportional. Both genders range from 17 to 31 inches in height and weigh anywhere from 5 to 15 pounds. Another very unique species I found in this tropic climate was the Red-Eyed Tree Frog. The thing you may notice at first would be the big, bulging red eyes; but I noticed their special way of camouflaging themselves. Although their eyes may be very noticeable, those big eyes are actually how they hide themselves from predators. When this species of frogs close their eyes, the eye lids are a vibrant...

...An important ecosystem service provided by forests is the ability to counter-act the effects of global warming. Carbon dioxide, a contributing factor to global warming, is taken up by the plants and vegetation contained in forests through photosynthesis and the resulting carbon is stored in both living and dead plant biomass. This process, known as carbon sequestration, greatly reduces the potential for global climate change (IPCC 2001). Forest cover also affects the albedo, that is, the proportion of incident solar radiation that is reflected by the earths surface. The dense green coloured canopy of tropical forests have a low albedo when compared with grasslands or deforested areas. This allows for more incident solar radiation to be absorbed and cooler air termperatures (O’Brien 1996). Perhaps the most important ecosystem service provided by forests, which is a basic requirement for life, is the supply of clean water. Forests facilitate the storage of clean water through filtering precipitation through the tree canopy. This, in effect, slows the rate at which precipitation collects at the ground surface allowing it to remain unsaturated. It is estimated that over 2/3 of the clean water supply is United States is contained within stream water, which was filtered through forests, with a direct value exceeding $27 billion per year (Snail 2009). This clean water can be captured and stored in watersheds that in turn, can be used for variety of purposes including agriculture,...

Indonesia overview Indonesia maintains the highest rate of illegal logging among other countries, up to 60% of timber production. Corruption has been a prevalent issue in Indonesia, and was even worse after the end of the Suharto government system. Deforestation rate is excessive from 1.3 to 2 million hectares every year. Indonesia represents about one-quarter of global tropical wood production and exports, and about half of global tropical hardwood plywood exports. Indonesia is one of the prime targets of international awareness on illegal logging and forest destruction operation (Creek 2004). According to Creek (2004), ‘The...

...Decline in Biodiversity Deanna Garrett ENV497 Chad Goings July 15, 2013 Decline in Biodiversity Biodiversity is important in ecosystems because every life form works together in order for them to function. When these ecosystems are disrupted or altered, or even lacks biodiversity, it poses major threats to all the life forms in it, whether it happens quickly or over a long period of time. When we lack biodiversity, our ecosystems become unstable, which in turn makes them more vulnerable to disasters and they cannot contribute to our well being. Although policy makers may be faced with challenges, many considerations need to be taken into account to preserve biodiversity and to protect these areas so that these ecosystems can function properly and prosper. When we hear the word ‘biodiversity’, it pretty much explains itself. It is the amount of variation of life forms within a given biome, ecosystem, species, or even the entire plant. Many considerations need to be taken into account to preserve biodiversity and to protect these areas so that these ecosystems can function properly and prosper. With respect to the ecosystem and biodiversity, we need to remember that once our natural resources run out and when most ecosystems are destroyed, it is very hard to restore it to what it was. We need to consider our well being, as well as all the other organisms that we share the earth with. We use biodiversity all the time, whether it is direct or indirect. In order for us to...
