One of the biggest concerns with smartphones these days is battery life. There are many different ways to help prolong your battery life, however I find turning off any services you are not using will help make the biggest impact. Some of these services include WiFi, Bluetooth, GPS, and your Mobile Network. The reason these services kill your battery life very quickly is because all the services I just named are always searching for a signal even if you are not using them. If you turn these services off when not in use the battery will be able to use its power more efficiently allowing for a longer battery life. All of these services can be turned on and off through the settings app, however some are easier to find than others. WiFi: 1. Open the Settings app 2. WiFi will be the second choice from the top. Next to the word WiFi will either be "OFF" or "ON" 3. Tap on the word WiFi to bring up another screen where you can switch from "ON" to "OFF&qu

In the previous post ( Databases Introduction )  we looked at different types of databases and simple concepts of tables. In this section, we will look at some basics of databases- tables, inner joins and outer joins. The syntax of SQL used here is for Oracle. However, it is very similar in all other databases such as MySQL, MS SQLServer, Postgres, etc.. Tables We will create two tables by using the SQL statements below:   create table customer (cust_id number(4,0) not null, customer_name varchar2(60) not null); create table invoice (invoice_id number(4) not null, cust_id number(4) not null , invoice_total number(10,2) default 0.00, paid_ind char(1)); In the first SQL we create the table called Customer with the column names cust_id and customer_name.
