Data dependency - Wikipedia
WEBA data dependency in computer science is a situation in which a program statement (instruction) refers to the data of a preceding statement. In compiler theory, the technique used to discover data dependencies among statements (or instructions) is called dependence analysis.
WEBThere is a data dependence, if There exist i1 r, i2 r, i1 w,i2 w, such that 0 ≤i1 r, i1 w ≤n, 2*i1 r ≤i2 r ≤100, 2*i1 w ≤i2 w ≤100, i1 w + 2*i2 w +3 = 1, 4*i1 w + 2*i2 w = 2*i1 r + 1 Note: ignoring non-affine relations for i1 = 1, n for i2 = 2*i1, 100 a[i1+2*i2+3][4*i1+2*i2][i1*i1] = … … = a[1][2*i1+1][i2] + 3
Data independence - Wikipedia
WEBData independence is the type of data transparency that matters for a centralized DBMS. It refers to the immunity of user applications to changes made in the definition and organization of data. Application programs should not, ideally, be exposed to details of data representation and storage.

WEBJul 20, 2021 · What is Data Dependency - A position in which an instruction is dependent on a result from a sequentially earlier instruction before it can be done its execution. In high-performance processors operating pipeline or superscalar techniques, a data dependency will learn an interruption in the flowing services of a processor pi

WEBJan 1, 2005 · Abstract. Dependencies are certain sentences of first-order logic that are of special interest for database theory and practice. There has been quite a bit of research in the last decade in investigating dependencies. A …
WEBData flow models provide a complementary view, emphasizing and making explicit relations involving transmission of information. Models of data flow and dependence in software were developed originally in the field of compiler construction, where they were (and still are) used to detect opportuni- ties for optimization.
