Tuple calculus was created by Edgar F. Codd to provide a database-query language. It typically consists of two calculi and domain.

What is the difference between relational tuple calculus and domain calculus?
Relational tuple calculus has its variables range over tuples, where domain relational calculus ranges its variables over the field values, or domain elements. Both types of calculus are subsets of first order logic.
What is the plural form of calculus?
There are several meanings to the word 'calculus.' The plural for calculus is 'calculi.' There is no plural for the calculus we use in mathematics.
How do you use Calculus in a sentence?
My Calculus class is in third period. Calculus is a noun
Which is harder differential calculus or integral calculus?
Im still taking Integral Calculus now, but for me, if you dont know Differential Calculus you will not know Integral Calculus, because Integral Calculus need Differential. So, as an answer to that question, ITS FAIR
Who started calculus?
there was no sure answer about who started calculus but it was Isaac Newton and Gottfried Wilhelm Leibniz who founded calculus because of their fundamental theorem of calculus.

Software on relational calculus?
MySQL
What are the main differences between relational algebra and relational calculus?
Relation algebra is a procedural language where relation calculus is non-procedural languageRelational algebra, an offshoot of first-orderlogic (and of algebra of sets), deals with a set of finitaryrelations (see also relation (database)) which is closed under certain operators. These operators operate on one or more relations to yield a relation. Relational algebra is a part of computer science.Relational calculus consists of two calculi, the tuplerelational calculus and the domain relational calculus, that are part of the relational model for databases and provide a declarative way to specify database queries. This in contrast to the relational algebra which is also part of the relational model but provides a more procedural way for specifying queries.The relational algebra might suggest these steps to retrieve the phone numbers and names of book stores that supply Some Sample Book:1. Join books and titles over the BookstoreID.2. Restrict the result of that join to tuplesfor the book Some Sample Book.3. Project the result of that restriction over StoreNameand StorePhone.The relational calculus would formulate a descriptive, declarative way:Get StoreNameand StorePhonefor supplies such that there exists a title BK with the same BookstoreIDvalue and with a BookTitlevalue of Some Sample Book.The relational algebra and the relational calculus are essentially logically equivalent: for any algebraic expression, there is an equivalent expression in the calculus, and vice versa.This result is known as Codd'stheorem
What are the different types of database languages?
Two main types: Relational Calculus based Language Relational Algebra based Language. These languages provide similar set of operations but with different syntax. Calculus based is more kind of procedural and near to English, while Algebra based uses a set of symbols for queries.

How would you classify the relational algebra and relational calculus?
1. Relational algebra operations manipulate some relations and provide some expression in the form of queries where as relational calculus are formed queries on the basis of pairs of expressions. 2. RA have operator like join, union, intersection, division, difference, projection, selection etc. where as RC has tuples and domain oriented expressions. 3. RA is procedural language where as RC is non procedural query system. 4. Expressive power of RA and RC are equivalent. This means any query that could be expressed in RA could be expressed by formula in RC. 5. Any KC formula is translated in Algebric query. 6. There is modification which is easy in queries in RA than the RC. 7 RA formed the mathematical form and have no specificjuer1 language RC also has mathematical form but has one query language QUEL. 8. Relational algebra is easy to manipulate and understand than RC. 9. RA queries are more powerful than the RC. 10. RC are formed WFFs where as RA does not form any formula.
Which is harder calculus or applied calculus?
Calculus; by a long shot.

Is elementary calculus the same as calculus?
Pre-calculus refers to concepts that need to be learned before, or as a prerequisite to studying calculus, so no. First one studies pre-calculus then elementary calculus.
