6. There are 4 important objects as stated in the table below:

7. Objects BarFunction Table A collection of records that identify a category of data, such as Customers, Orders, or Inventory. Data inside a table is arrange by column name field and row named Record.  Field – A single characteristic or attribute of a person, place, object, event, or idea.  Record – A set of related field values. Form Use to enter new information, to edit or remove existing information or to locate information. Query Used to locate information, to view, change or analyze it in various ways. A select query retrieves data from one or more tables and displays the result in datasheet. A select query can be used to group record and calculate sums, counts, averages and other types of totals. Report Typically used to summarize, organize and analyze information in order to express a particular point of view to specific audience.

8. There are 10 types of data as stated in the table below:

9. Types DataFunction Text You may type in any alphabetical/numerical data that you desire-up to a maximum of 255 characters. As indicated, this is a text field, so you can't do mathematical calculations. Examples of Text data are: names, addresses, stock numbers, room numbers, zip codes, etc Memo This field is for lots of text. You can have up to 32,000 characters. Number This field is for numbers where you want to add, subtract, multiply, divide, average, and do numerical calculations. This field can be a very large size, so when we get to Field Properties, we'll talk about "sizing" this field so it doesn't take up too much "space" in storage.

10. Date/Time Dates and Times. You may format this later, as you may desire. Currency Dollar ($). You may format this later, as you may desire. For example Ringgit Malaysia (RM) AutoNumber This field is an "automatic" counter that assigns a number each time you put data into a new field. Yes/No This is a "True/False" or "Yes/No, 0/1” type of field.

11. OLE Object This means "Object Link Embedding" which indicates you can insert a graphic, picture, sound, etc. Pretty neat to put a photograph in a personnel record or a picture of an inventory item in the stock record (advanced stuff). Hyperlink A hyperlink is a pointer from one object to another. The destination is frequently another Web page, but it can also be a picture, an e-mail address, a file (such as a multimedia file or Microsoft Office document), or a program. The hyperlink itself can be displayed as text or as a picture. Lookup Wizard This wizard creates a lookup column, which displays a list of values you can choose from.

12. ADVANTAGES OF DBMS Controlling Redundancy Integrity can be enforced Inconsistency can be avoided Data can be shared Standards can be enforced

13. Restricting unauthorized access Solving Enterprise Requirement than Individual Requirement Providing Backup and Recovery Cost of developing and maintaining system is lower Data Model can be developed

14. DISADVANTAGES OF DBMS Complexity Size Performance Higher impact of a failure Cost of DBMS

15. Additional Hardware costs Cost of Conversion

16. PRIMARY KEY means the value in the primary key fields is need to uniquely identify each record; that’s no record can have the same value in this field.
