input question: Information:  - Computer science is the study of the theory, experimentation, and engineering that form the basis for the design and use of computers. It is the scientific and practical approach to computation and its applications and the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information. An alternate, more succinct definition of computer science is the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems.  - An oxoacid is an acid that contains oxygen. Specifically, it is a compound that contains hydrogen, oxygen, and at least one other element, with at least one hydrogen atom bound to oxygen that can dissociate to produce the H cation and the anion of the acid.  - A transaction symbolizes a unit of work performed within a database management system (or similar system) against a database, and treated in a coherent and reliable way independent of other transactions. A transaction generally represents any change in database. Transactions in a database environment have two main purposes:  - A database is an organized collection of data. It is the collection of schemas, tables, queries, reports, views, and other objects. The data are typically organized to model aspects of reality in a way that supports processes requiring information, such as modelling the availability of rooms in hotels in a way that supports finding a hotel with vacancies.  - A basic oxide is an oxide that shows basic properties in opposition to acidic oxides and that either reacts with water to form a base ; or reacts with an acid to form a salt and water . Examples include : Sodium oxide , which reacts with water to produce sodium hydroxide Magnesium oxide , which reacts with hydrochloric acid to form magnesium chloride Copper ( II ) oxide , which reacts with nitric acid to form copper nitrate Basic oxides are oxides mostly of metals , especially alkali and alkaline earth metals .  - In computer science, ACID ("Atomicity, Consistency, Isolation, Durability") is a set of properties of database transactions. In the context of databases, a single logical operation on the data is called a transaction. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction.  - Acidic oxides are oxides that react with water forming an acid; or react with a base forming a salt. They are oxides of either nonmetals or of metals in high oxidation states. They are formed when a nonmetal burns. Their chemistry can be systematically understood by taking an oxoacid and removing water from it, until only the oxide is left. The resulting oxide belongs to this group of substances.    What entity does 'basic oxide' has the relation 'has part' with????
output answer: oxygen

input question: Information:  - Georges Joseph Christian Simenon (13 February 1903  4 September 1989) was a Belgian writer. A prolific author who published nearly 500 novels and numerous short works, Simenon is best known as the creator of the fictional detective Jules Maigret.  - Maigret in Exile ( French : La Maison du Juge ) is a 1940 detective novel by the Belgian mystery writer Georges Simenon .  - Jules Amedée François Maigret , simply Jules Maigret or Maigret to most people, including his wife, is a fictional French police detective, actually a "commissaire" or commissioner of the Paris "Brigade Criminelle" (Direction Régionale de Police Judiciaire de Paris), created by writer Georges Simenon.    What entity does 'maigret in exile' has the relation 'characters' with????
output answer:
jules maigret
