To understand the what the advantages of a declarative language as opposed to a procedural language, we must understand the difference in the midst of the two. A procedural language such as FORTRAN or entreat (There are more) give precise instructions that tell the computer what to do. In other words a procedural language is your basic if-this, then-that. circumstantial variables are defined that tell the CPU how to process information. It takes a software engineer that knows the intimate details of how the code works to ensure that programs work the look they are supposed to.In a declarative language, language is employ that in its simplest form, just makes maven. There is no intricate code that is confusing. atomic number 53 example in SQL would be creating tables CREATE TABLE Employee. The intentionr piece of tail create a simple table without having to know the inner kit and boodle of how the table is actually created.The advantage of declarative language is that it m akes life so much easier for the everyday user to function in declarative programs without existence a programmer. When a user types something in, the language just makes more sense to the everyday user and there is also plenty of information that discharge be found to aid in using declarative languages.adjective language can have its advantages though. This is true for security designers. This allows only those that are developing a program to know the inner workings of the program. In my opinion it is a good deterrent for unskilled soulfulnesss to make modifications to programs that use procedural language.Cross joins are legitimate for several reasons. The main reason is to cut down the amount of information that the database is searching for. This also acquired immune deficiency syndrome in increase performance. If cross joins were non allowed then the program would drive away much more information that is needed resulting in increased duration to sort the data. This is e xample is two- fold the database would work harder to retrieve information and the person looking at the returned information would have to work harder to sort it.I could imagine persons that are making inquiries across a WAN linkup via a VPN making an inquiry and needing that specific data quickly. If cross joins were not allowed then can one imagine how much data is creation sent across the internet or how much bandwidth is being use? In addition to that idea what about the integrity of data that any given person has access too? Cross joins allow for increased productivity, less strain on the database resources and security filtering of information.References-http//www.academia.edu/306590/A_COMPARISON_OF_DECLARATIVE_AND_PROCEDURAL_CONSTRAINTS_IN_DATABASE_MANAGEMENT_SYSTEMShttp//www.teach- www.teach-ict.com/as_as_computing/ocr/H447/F453/3_3_6/types_language/miniweb/pg3.htm
