He had also heard about the IBM System R database from an article in the "IBM Research Journal" by Ed Oates. System R was also based on Codd's theories. Ellison wanted to make Oracle's product compatible with System R, but IBM stopped this by keeping the error codes for their DBMS ("DataBase Management System") secret. Ellison co-founded Oracle Corporation in 1977 with Bob Miner and Ed Oates under the name Software Development Laboratories (SDL). In 1979 SDL changed its name to Relational Software, Inc. (RSI). In 1982, RSI renamed itself Oracle Systems to make the relation to its main product, Oracle Database, clearer. At this stage Bob Miner was the company's senior programmer. In 1995, Oracle Systems Corporation changed its name to Oracle Corporation.
Part of Oracle Corporation's early success came from using the C programming language to install its products. This made changing the setup to different operating systems (most of which support C) easier.
Queen (butterfly)
The Queen ("Danaus gilippus") is a species of butterfly. It belongs in the family Nymphalidae. It is found in North America, Central America, and South America.
The upper side of the wings is dark reddish-brown. It has black wing borders. Males have an androconium (a spot that releases scents to attract females) on each of his hind wings (bottom wings). The underside of the wings is reddish-brown. The wings have black borders. There are white spots in the black borders. The hind wing has black veins.
The Queen is one species in a complex mimicry ring. Where their range overlaps, the appearance of these butterflies is similar. The Monarch ("Danaus plexippus") is orange. It has thick, black veins. The Viceroy ("Limenitis archippus") is smaller. It has thick, black veins. It has a black band across the hind wing. The Soldier ("Danaus eresimus") has thin black veins. On the underside of the hind wing, there is a row of pale, square-shaped spots.
Monarchs are bad-tasting and poisonous because they contain a chemical known as cardenolide (cardiac glycoside). The chemical slows the heart-beat of vertebrates. Monarch caterpillars get this chemical when they feed on milkweed.
When the Monarch becomes a butterfly, it no longer eats milkweed, but it still has the chemical in its body. The butterfly shows that they are not good to eat with their bright orange and black wings. This is warning coloration. A bird may try to eat a Monarch, but it will become sick and vomit after eating it. After this experience, the bird learns not to eat another Monarch, and also any other butterfly which is similar in appearance.
The Viceroy is similar looking to the Monarch, but does not have the milkweed poison in its body. Birds that have had the bad experience of eating a Monarch will usually not eat a Viceroy. It is an example of Batesian mimicry. Or so it was thought; but recent work has challenged this. The difficulty in doing this kind of research is that a butterfly may be toxic in one part of its range, and good to eat in another part. A lot depends on the plants on which the eggs are laid.
The Queen is one of many insects that derives chemical defenses against its predators from its food plant. Most of the toxic cardenolides that make queens so unpalatable to its predators are sequestered from larval host plants. Basically, the Queen shares a Müllerian mimicry with the Monarch. However, the extent of its toxicity varies a great deal in different parts of its range. Micro-geographic differences in the environment lead to variation in the dynamics of mimetic relationships even at a local level.
The Queen can be seen all year in Texas, Arizona, and southern Florida. It is seen from February to December in northern Florida. It is seen from April to November in southern California and southern Nevada.
This butterfly can be found in open places such as open woodlands, fields, deserts, marshes, and forest edges.
The female lays her eggs singly. They are laid on the leaves, stems, and flowers of the host plant (the host plant is the plant that the caterpillar feeds on). The egg is pale green. The caterpillar is banded with yellow and black. There are three pairs of black body extensions. The first pair is near the head. The second pair is on the thorax. The third pair is near the end of the body. The chrysalis is green. It has gold spots. There is a black and gold band on the abdomen. It is very similar to the Monarch's chrysalis. It has three or more broods (a brood is a group of offspring) per year.
Here is a list of host plants that the Queen caterpillar feeds on:
2006 North Indian Ocean cyclone season
The 2006 North Indian Ocean cyclone season ran through all of 2006. Though most storms in this area start between April and December. This was the first year the cyclones got named in the northern Indian Ocean. There was about $6.7 million in damage and about 192 people got killed in 2006 because of the cyclones.
Deep Depression ARB 01 or Tropical Cyclone O1A stared on January 13 to the south of India. It died on the next day.
Mala started as Tropical Cyclone 02B on April 25 and became Cyclonic Storm Mala later on that day. It headed northeast and later it became a very sever cyclonic storm. Mala made landfall in Myanmar on April 29, the winds were close to 115 mph. The cyclone died over Myanmar later that day. Mala killed about 22 people.
Tropical Cyclone 02 started on July 2 near India. The cyclone made landfall in India later that day and it survived until July 5.
This Deep Depression was Tropical Cyclone 03 and started on August 2. By August 5 it had died.
The fifth depression in 2006 started on August 12 and it died on August 13.
This depression lasted from August 16 to August 18.
This depression started on August 29 and it died on September 1.
Depression BOB 07 started on September 3 and died by the next day.
This depression started on September 21. It later made landfall near the India and Bangladesh border. It died on September 24. The cyclone killed about 170 people.
Mukda started in the Arabian Sea on September 21. It became a strong tropical storm over the next few days. It died on September 24.
This depression started on September 28. On September 29 it made a landfall in India. The cyclone died on the next day over India.
Ogni was the final cyclone that started on October 29 as a deep depression. It moved very slowly and made a landfall in India. Cyclonic Storm Ogni died on October 30, after it killed at least 35 people.
These three names got used in the 2006 North Indian Ocean cyclone season:
