Oracle Database

External schemas allows data access to be customized (and authorized)

at the level of individual users or groups of users. Conceptual (logical) schemas describes

all the data that is actually stored in the database. While there are several

views for a given database, there is exactly one conceptual schema to all users. Internal

(physical) schemas summarize how the relations described in the conceptual schema

are actually stored on disk (or other physical media).

External schemas provide logical data independence, while conceptual schemas offer

physical data independence.

In most cases your abuser considers you a "loss" and will move on to finding someone else he can abuse. Consider yourself lucky and never think twice about this guy. There are great programs for Abused Women, and I suggest, if you have just left an abuser or you know someone that has, to seek out this help. They help you gain your self esteem and confidence, they counsel you, help you find work if you don't have one, and will also help with legal counsel if need be. If you have children they will help in this area as well.

Entities are the things you're keeping track of. In an video rental database, you keep track of customers, invoices, titles, copies, etc. These are represented in tables where the rows are individual instances of a customer or title. The columns are the attributes, the things that tell us about the instance in the row. The customer's name, address, city, balance, etc. are attributes that help identify the customer. An invoice's attributes might be price, number, date, paid/unpaid, etc. Databases link entities/tables so that a customer, described by his attributes, can be associated with his invoices, describe by his attributes and selected by the invoices 'unpaid' column. "Here's your bills for the last month, Mr. Smith."

RLB - Redolog Buffer Background Process:- 1. Mandatory Processes- a. SMON - System Monitor b. PMON - Process Monitor c. DBWR - Database writer d. LGWR - Log Writer e. CKPT - Check point f.
