Access -A software you use to create and manage databases. A form of DBMS (Data Base Mangement System).
Things you can have in a database: Tables, Queries, Pages, Macros, Modules, Reports and Forms.
Fields - Column headings.
Field size- default:50 characters (maximum 256 characters)
Fiddle around with all the features before database is created.
Different Data Types for settingup a table
-text and memo's are the same thing but memo's are longer (more limit).
-number - different types of numbers. 7 options. It affects how much storage space is neede for each number. It can be varied a bit.
-Date/time and currency - Part of a number that is set in a particular format/way.
-Auto number - This can be used as an ID field. IT makes sure you have a different number for each record
-yes/no - also called a boolean data field (field with only 2 options)
-OLE object - How they attach it to a database.
-Hyperlink - website
-Lookup Wizard - If you have a table already done. The lookup wizard helps you find the table. It is looking up what you neeed to find.
A Primary Key: A key field which will alow you to assicate a record in this table to a record in anothe table. It is some bit of data that is somewhat unique. Every table has their own unique key. If you don't have a primary key you can't link the table to other tables.
e.g in school system each student has an ID number which will make them unique.
The process involved in making a table is COLLECTING. If it was setup so that it would go in alphabetical order it would be ORGANISING.

What is it as a system?
Released on March 11, 2009. Google Voice is a free Google-owned internet service that uses VOIP (Voice Over Internet Protocol) to link customers.
What is it likely to do for the users?
Features of Google video include:
-A single Google number for all user's phones.
-Free calls and SMS in the contiguous US and Canada.
-Calling International phone numbers for as low as 0.01 USD per minute.
-Call screening. Announce callers based on their number or by an automated identification request for blocked numbers.
-Listen in on someone recording a voicemail before taking a call.
-Block calls.
-Send, receive, and store SMS online.
-Answer an incoming call on any of your phones.
-Phone routing. Choose which phones should ring based on who calls.
-Forwarding phones.
-Voicemail transcripts. Read voicemails online.
-Listen to voicemail online or from a phone.
-Receive notifications of voicemails via email or SMS.
-Personalized greeting that vary greetings by caller.

-Conference calling.
-Record calls and store them online.
-Switch phones during a call.
-View the web inbox from a mobile device/phone.
-Set preferences for contacts by group.
-Ability to change your number for a fee.
What benefits will it have for the users?
-Cheaper
-Google voice applications in smartphones can automatically forward outgoing calls via the user's Google Voice number instead of the device's phone number.
-It provides all users with the features mentioned above; One device, many features; thus less things to own.
What are the consequences in other areas? e.g- normal phone companies
-If people make the switch to use VOIP services (google voice), normal phone companies may eventually come to end due to lack of payment from users. This is because more people will make a move towards the VOIP services and thus they will earn less money.
-When a Google Voice user returns a call, the party being called sees the device's number as opposed to the Google Voice number which sometimes confuses the receiver. To recognize calls from a Google Voice user, someone must store several different numbers in their phone.
What do you think are some of the hardware involved in this system is likely to be?
-microphone
-cell phone
-home phone
-work phone
What are some of the processes involved?
-collecting -information such as names of contacts and their number, collecting voice projections through the microphone
-organising - organising numbers under contact names, organising sounds into words/identifying what sound is what letter and language (translation)
-displaying - on the screen who is calling, who you are calling and displaying the things that you say into letters and words on screen
-transmitting and receiving - sounds back and forth in calls, emails and voicemail
-storing and retrieving - messages/mail/voicemail in phone, phone numbers, records callas and stores them online

From the 30th of June to the 10th of August 2009, Emily, Aakriti and I have been doing a group project. The project is based on tennis. Refer to Emily's ipt blog for the theory work. Here is the Gantt Chart to show who did what in this assessment and also approximately how long it took for each task to be done. The yellow rectangles were done by the whole group. The pink by Aakriti, the purple by Emily and the blue by me. The tasks included were planning, Tennis homepage, How to play/rules, ranking system, history of tennis, global ranking, key players, about us, requirement report, context diagram, data flow diagram and last but not least the integration of webpages. Here is the gantt chart with a key so that you know who did what.
