   • Procedural and non-procedural query language difference

     Top Answer

     Answered Nov 22, 2017 · 2 votes

     There is a myth that relational algebra notations are procedural and relational calculus notations are not. But every relation expression corresponds to a certain calculus expression with the same tree structure. So it cannot be procedural when calculus is not. You can implement/execute a query in either notation per its expression tree--or not.

     A (query) language is procedural when it has to use looping or otherwise relies on state. The alternative is often called declarative or functional.

     Any database notation that updates the database is procedural, including SQL. But that's not "querying". Typically DBMSs have extensions to SQL that allow you to partially control query execution and/or data storage order in terms of implementations concepts; that's non-procedural. But that's not SQL.

   • Procedural Programming with UML Modelling

     Top Answer

     Answered Mar 14, 2014 · 6 votes

     UML has many diagrams. Only class diagrams are done directly for OOP conception. Object and Composite structure diagrams are not so strict already.

     All other diagrams can be used without and apart from the OOP. Sequence, Timing, Activity, Communcation, Use case, Interaction Overview, State Machine, Package, Deployment, and Component diagrams work OK.

     So, the only diagram not for the direct use is the class diagram, that you simply needn't in the functional programming.

   • Procedural circle mesh with uniform faces

     Top Answer

     Answered Nov 21, 2018 · 11 votes

     You got me interested with your question, and I think I've got the solution you were looking for. Here is how we can create a topology that you desired:

     1) We start with a hexagon. Why hexagon and not other shape? Because hexagon is the only magic shape with its radius equal too the length of its side. We will call this radius R. We will now try to create a shape that resembles circle and is made of triangles with side length approximately R.

     2) Now imagine some concentric circles, with radius R, 2R, 3R and so on - the more, the higher is the resolution.

     3) Circle number 1 has radius R. We will now replace that circle with a hexagon with radius R.

     4) We will now add more nodes on second circle to expand our hexagon. What is the circumference of circle number N? It is 2PiRN. Now we want to divide it into X edges of length approximately R. Hence X=2PiN, which is approximately 6N. So we will divide first circle into 6 edges (hexagon), second one into 12, then 18, 24 and so on.

     5) Now we have lots of circles divided into edges. We now need to connect edges into triangles. How do we build triangles between circle N (outer) and N-1 (inner)? Outer circle has 6 more edges than the inner one. If they had identical number of vertices, we could connect them with quads. But they don't. So, we will still try to build quads, but for each N quads we build, we will need to add 1 triangle. Each quad uses 2 vertices from inner and 2 vertices from outer circle. Each triangle uses 2 vertices from the outer circle and only 1 from inner, thus compensating the excess of vertices.

     6) And now at last, there is some tested sample code that does what you need. It will generate a circle with uniform topology, with center point at origin and radius of 1, divided into *resolution sub circles. It could use some minor performance optimization (that's out of scope for now), but all in all it should do the job.

     using System.Collections.Generic;using UnityEngine;-[RequireComponent(typeof(MeshFilter))]public class UniformCirclePlane : MonoBehaviour {- public int resolution = 4;- // Use this for initialization void Start() { GetComponent<MeshFilter>().mesh = GenerateCircle(resolution); }- // Update is called once per frame void Update() {- }- // Get the index of point number 'x' in circle number 'c' static int GetPointIndex(int c, int x) { if (c < 0) return 0; // In case of center point x = x % ((c + 1) * 6); // Make the point index circular // Explanation: index = number of points in previous circles + central point + x // hence: (0+1+2+...+c)*6+x+1 = ((c/2)*(c+1))*6+x+1 = 3*c*(c+1)+x+1- return (3 * c * (c + 1) + x + 1); }- public static Mesh GenerateCircle(int res) {- float d = 1f / res;- var vtc = new List<Vector3>(); vtc.Add(Vector3.zero); // Start with only center point var tris = new List<int>();- // First pass => build vertices for (int circ = 0; circ < res; ++circ) { float angleStep = (Mathf.PI * 2f) / ((circ + 1) * 6); for (int point = 0; point < (circ + 1) * 6; ++point) { vtc.Add(new Vector2( Mathf.Cos(angleStep * point), Mathf.Sin(angleStep * point)) * d * (circ + 1)); } }- // Second pass => connect vertices into triangles for (int circ = 0; circ < res; ++circ) { for (int point = 0, other = 0; point < (circ + 1) * 6; ++point) { if (point % (circ + 1) != 0) { // Create 2 triangles tris.Add(GetPointIndex(circ - 1, other + 1)); tris.Add(GetPointIndex(circ - 1, other)); tris.Add(GetPointIndex(circ, point)); tris.Add(GetPointIndex(circ, point)); tris.Add(GetPointIndex(circ, point + 1)); tris.Add(GetPointIndex(circ - 1, other + 1)); ++other; } else { // Create 1 inverse triange tris.Add(GetPointIndex(circ, point)); tris.Add(GetPointIndex(circ, point + 1)); tris.Add(GetPointIndex(circ - 1, other)); // Do not move to the next point in the smaller circle } } }- // Create the mesh var m = new Mesh(); m.SetVertices(vtc); m.SetTriangles(tris, 0); m.RecalculateNormals(); m.UploadMeshData(true);- return m;- }}-

   • Procedural approach in JavaScript

     Top Answer

     Answered May 23, 2017 · 7 votes

     Let's start by saying the above is a self-invoking anonymous function:

     A self-invoking anonymous function runs automatically/immediately when you create it and has no name, hence called anonymous.

     The above is a fairly poor example in my opinion, but consider the following change:

     var f = (function (){ var b = 10, c = 20, d = 50; var e = function(){ return b + c + d; }; return e();}());​console.log(f);​

     We've taken the above code and added a var f = in front of the function. This returns the value of e() from the inner function to f and now you have a value f to be used elsewhere. Since the variables b, c, d, e are declared within the function scope of the anonymous function, we can ensure that they will not be tampered with. This is a way to do private variables in JavaScript. Now say you had 10 + 20 + 50 may places within your code. You could run this anonymous function at the beginning and substitute those occurrences with f. This idea of abstracting out code into various procedures is why it's referred to as Procedural Programming.

     Procedural programming uses a structured approach to coding the program where the functionality of the program is broken down into a number of functions or subroutines to make it easier to follow and reduce the need to repeat code.

     This is mainly used to make code easier to read, easier to follow/debug and lets you abstract commonly used chunks of code into well written snippets of code.

   Procedural programming is a programming paradigm, classified as imperative programming, [1] that involves implementing the behavior of a computer program as procedures (a.k.a. functions, subroutines) that call each other. The resulting program is a series of steps that forms a hierarchy of calls to its constituent procedures.
