Correspondence between relational algebra (Relation Algebra) and SQL statements

The execution of SQL statements is generally translated into relational algebra and then executed (which can effectively improve execution speed), so we need toUnderstand the correspondence between relational algebra and SQL statements.Just like high school algebra consists of +-*/and numbers, relational algebra is com

On the symbolic calculus in Banach algebra 1. Symbolic calculus in general Banach algebra

Rudin's This "functional analysis" is really not very good to read, in general, because the books in the details of the place is indeed too much, not very good grasp. I look at this book with the purpose of learning operator algebra, so I don't want to fall into the function space, especially the Fourier transformation problem associated with it, soAfter studying the relevant knowledge about the topological and space, the local convex space and the co

algebraic system of two-dollar operation, referring to the examples are mainly from number theory and permutation transformation. The following discussion will be more verbose in the analysis of ideas, but these are the essence of abstract algebra, and some of the proof process and results are less important. I hope you can always close your books and reconstruct these theories and experience the thinking of abstract

How do you understand "linear algebra"? _ Linear algebra

What is the practical significance of linear algebra? What is the matrix? What does the operation between matrices represent? Many people still don't understand these questions at school, so I think we should start with understanding the nature of the course. There are only a few articles or answers that provide an understanding of the nature of linear algebra. Bloggers repeatedly read several times to dee

Implement custom converter and global converter in struts2

There is a field in the action that is of the birthday or date type. When we pass the value, it must be written as to automatically convert the type, however, in some cases, you may need to write 19990101 so that automatic type conversion is not performed by default. In this way, you can write a custom type converter to achieve conversion. Struts2 has two types of converters: Partial: it applies to an action conversion type. First, you need to customi
