The cell cycle is the complex sequence of events by which cells grow and divide. In eukaryotic cells, this process includes a series of four distinct phases. These phases consist of the Mitosis phase (M), Gap 1 phase (G 1), Synthesis phase (S), and Gap 2 phase (G 2) .The G 1, S, and G 2 phases of the cell cycle are collectively referred to as interphase.n eukaryotic cells, this process includes a series of four distinct phases.

A database query is a piece of code (a query) that is sent to a database in order to get information back from the database. It is used as the way of retriving the information from database. A database query is basically a question that you ask the database.
A query is a request for information from a database. It can be as simple as finding the address of a person with SS# 123-45-6789, or more complex like finding the average salary of all the employed married men in California between the ages 30 to 39, that earn less than their wives..ach different way typically requires different processing time. Processing times of the same query may have large variance, from a fraction of a second to hours, depending on the way selected. The purpose of query optimization, which is an automated process, is to find the way to process a given query in minimum time.
