An intermediate node of a Bt-tree

1 B+-Tree File Organization
Consider a relation R with 48,000 records. This relation has 4 attributes. The sizes of each attribute are: 6 bytes, 12 bytes, 4 bytes, and 18 bytes, respectively. The first attribute is the primary key. We wish to store R as a Be-Tree file on the disk, using the primary key of It as the search key. The size of a pointer is 4 bytes. Each block (i.e., page) is 512 bytes. [Flint: Since we have a Be-tree file organization, what do the leaves of the tree contain? The actual records of R, or pointers to records of 11?)
1.1 What are the maximum number of keys, and the maximum number of pointers (n), that an intermediate node of this Be-tree can have? (5 points)
1.2 What is the minimum number of pointers, allowed in an intermediate node of this Bt-tree? (5 points)

may themselves feel out of place according to their own ascribed traits (differences based on class, privilege, and so on.). Assessing and thinking through notions of difference and the way they affect the classroom allow both students and teachers to find the classroom as an inclusive location (Diversity in the Classroom, 2007). Critical race theory Critical race theory (CRT), is defined as the view that race, instead of being biologically grounded and natural, is socially constructed and that race, as a socially constructed concept, functions as a way to maintain the interests of the white population that assembled it (Curry, T. (2016). Based on CRT, racial inequality emerges in the societal, economic, and legal gaps in which Caucasian individuals create between “races” to keep elite Caucasian interest in labor politics and markets and as such produce the conditions that provide rise to poverty and criminality in many minority communities (Curry, T. (2016). Although the intellectual roots of this movement go back much further, the CRT movement officially organized itself in July 1989. The initiation of the CRT motion in 1989 indicated its separation from critical legal studies. Instead of drawing theories of social organization and individual behavior from continental European thinkers such as G.W.F. Hegel and Karl Marx or psychoanalytic figures like Sigmund Freud because its theoretical predecessors, as CLS and feminist jurisprudence had completed, CRT was inspired by the American civil rights heritage through figures like Martin Luther King, Jr. (Curry, T. (2016). Being steeped in a revolutionary black idea and civic thinking, critical race theory complex theoretical understandings of the law, politics, and American sociology that concentrated on the attempts of white folks (Euro-Americans) to maintain their historical benefits over individuals of color (Curry, T. (2016).
