In data presentation of computing
systems and applications, when a user click the submit button on the form, the
name-value pair of each form is sent because it is an open-ended data structure
that allows future extension without altering existing code or data.
Answer:
Here’s one!
Given [math]R[/math], the radius of the circle.
Let [math]N,D\leftarrow 0[/math]
Repeat until [math]D[/math] is large enough (about 1,000,000)
[math]x,y\leftarrow U[0,1][/math]
If [math]x^2 + y^2\le 1[/math] then [math]N\leftarrow N+1[/math]
[math]D\leftarrow D+1[/math]
[math]P\leftarrow\frac{8NR}{D}[/math]
Return [math]P[/math]
[math]U[0,1][/math] is a uniform random number in the range [math][0,1][/math].
Explanation:
A programming language that supports relational databases is SQL (Structured Query Language)
Structured Query Language (SQL), is the principal method for communicating with Relational Databases.
A relational database is a group of data elements that are linked together by predefined connections. These elements are laid up in the form of a series of tables containing columns and rows.
- Tables are utilized for storing data about the items that will be displayed in the database.
- A column in a database contains a specific type of data, whereas a field records the actual value of an attribute.
- The table's rows indicate a collection of linked values for a single item or entity.
Each entry in a database can be assigned a unique identity known as a primary key, and rows from other tables can be linked together via foreign keys. This data may be accessible in a variety of ways without having to reorganize the database tables itself.
