Question: The Warsaw Pact (formally, the Treaty of Friendship, Co-operation, and Mutual Assistance, sometimes, informally WarPac, akin in format to NATO) was a collective defense treaty among Soviet Union and seven Soviet satellite states in Central and Eastern Europe in existence during the Cold War. The Warsaw Pact was the military complement to the Council for Mutual Economic Assistance (CoMEcon), the regional economic organization for the communist states of Central and Eastern Europe. The Warsaw Pact was created in reaction to the integration of West Germany into NATO in 1955 per the Paris Pacts of 1954, but it is also considered to have been motivated by Soviet desires to maintain control over military forces in Central and Eastern Europe.

Question: In this paper, he described a new system for storing and working with large databases. Instead of records being stored in some sort of linked list of free-form records as in CODASYL, Codd's idea was to use a "table" of fixed-length records, with each table used for a different type of entity. A linked-list system would be very inefficient when storing "sparse" databases where some of the data for any one record could be left empty. The relational model solved this by splitting the data into a series of normalized tables (or relations), with optional elements being moved out of the main table to where they would take up room only if needed. Data may be freely inserted, deleted and edited in these tables, with the DBMS doing whatever maintenance needed to present a table view to the application/user.
Try to answer this question if possible: What model couldn't solve the problem of databases where information was missing?
Answer: unanswerable
Question: The party was a member of the Labour and Socialist International between 1923 and 1940.

Question: Differences in feasts may also originate from doctrinal issues—the Feast of the Assumption is such an example. Given that there is no agreement among all Christians on the circumstances of the death, Dormition or Assumption of Mary, the feast of assumption is celebrated among some denominations and not others.  While the Catholic Church celebrates the Feast of the Assumption on August 15, some Eastern Catholics celebrate it as Dormition of the Theotokos, and may do so on August 28, if they follow the Julian calendar. The Eastern Orthodox also celebrate it as the Dormition of the Theotokos, one of their 12 Great Feasts. Protestants do not celebrate this, or any other Marian feasts.
Try to answer this question if possible: When Mary finished attending all of the Feasts, what were the Feasts referred to as?
