The third American orbiter, Atlantis, scheduled for launch in the coming days for his final mission. NASA has indeed made ​​the decision to subcontract the supply of the ISS to private companies (SpaceX and Orbital Space Corporation) for cost reasons. European and Japanese cargo ships, however, some continue refueling missions. The Soyuz will continue to lead and bring the rotating crews of the ISS.
The ISS initiative was taken in 1984 by U.S. President Ronald Reagan. The scientific objective is to conduct experiments in microgravity. On the diplomatic front, is one of the largest international collaborations. The United States, Russia (which joined the project in 1993), Canada and eleven European countries, including France, are participating actively. The first module was launched in 1998. The station is now 100m long and contains several laboratories and a habitation module. Two Soyuz rescue are anchored permanently in case of trouble. About 2500 square meters of solar panels provide 100 kilowatts of electricity required to self-structure. The engines of cargo ships moored in turn allow the correction of the regular orbit of the ISS which is steadily losing altitude.

Several major Web companies like Google, Facebook and Akamai, participate, Wednesday, June 8, the " Day of IPv6 " . For 24 hours, these groups, but also over 400 other participants, test in real conditions, this new version of Internet Protocol (IP) which allows computers to communicate over the Internet.
Thirty years after the creation of the first Internet addresses, the stock of available IP addresses has been officially sold out in February , and IPv6, is designed to remedy. With the proliferation of connected devices, cameras to multimedia tablet through the video game consoles, the world has hit the ceiling of the four billion addresses available under IPv4.
SLOW TRANSITION
The transition to IPv6, that most users should not even notice, provides sextillions Address 340, or 340 multiplied by 10 to the power 36. The effort and investment required to switch to IPv6 based primarily on service providers, who must ensure that their networks can handle these new addresses and routing traffic.

But according to a study by the OECD , published in April 2010, the road is still long for the new protocol is widely adopted. The Organization for Economic Cooperation and Development last year, only 1% of sites managed IPv6.

Database Is a collection information stored in computer systematically so that it can be checked using a computer program to obtain information from the database. Software used to manage and call query (query) Database called database management system (database management system, DBMS). Studied in database systems information science.
The term "database" originated from computer science. Although then the meaning is more widespread, putting things outside the field of electronics, this article about a computer database. Note that similar to the data base was already there before the industrial revolution in the form of ledgers, receipts and collection of data related to the business.
The basic concept of the database is a collection of records, or pieces of knowledge. A structured database has an explanation of the types of facts that are stored in it: this explanation is called scheme. The scheme describes the objects that represented a data base, and the relationship between these objects. There are many ways to organize the scheme, or model the database structure: these are known as database model or data model. The model commonly used today is relational model, Which, according to Layman terms represents all information in the form of tables that are interconnected with each table consisting of rows and columns (the true definition uses mathematical terminology). In this model, the relationship between tables are represented premises using the same values ​​between tables. Other models such as hierarchical model and network model use a more explicit way to represent relationships between tables.
Term database refers to the collection of data that are interconnected, and the software should be referred to as database management system (database management system / DBMS.) If the context is clear, many administrators and programmers use the term data base for both these meanings.
