Why Learn Databases? STORE INFORMATION * 07/16/96 Why Learn Databases? STORE INFORMATION Information is a valuable commodity Information is used for marketing and BI (Business Information) Used by all kinds of businesses Access to good information (if properly done) Market to individuals creatively, rather than “mass mailing”, more customized (Business Intelligence) *

Database Terms DATASET * Database Terms 07/16/96 DATASET According to Dictionary.com, a database is “a comprehensive collection of related data organized for convenient access, generally in a computer.”  usually refers to data selected and arranged in rows and columns for processing by statistical software. The data might have come from a database, but it might not have. Simply put, an: “ORGANIZED COLLECTION OF DATA.” http://stackoverflow.com/questions/7782594/what-is-the-difference-between-dataset-and-database *

Database Terms DATABASE * Database Terms 07/16/96 DATABASE A COMPREHENSIVE collection of RELATED data organized for convenient access A database is usually under the control of a DATABASE MANAGEMENT SYSTEM, which is software that, among other things, manages MULTI-USER ACCESS to the database. (“usually”, but not necessarily. ) http://stackoverflow.com/questions/7782594/what-is-the-difference-between-dataset-and-database *

Database Terms DATABASE MANAGEMENT SYSTEM (DBMS) * 07/16/96 DATABASE MANAGEMENT SYSTEM (DBMS) Provides TOOLS needed to organize data in a flexible manner. It includes: facilities to ADD, MODIFY or DELETE data Never DELETE, instead flag the data as REDUNDANT. ask questions (queries) about the data stored produce reports *

* BENEFITS: 07/16/96 They are able to STORE LARGE AMOUNTS OF DATA and SORT it according to your needs. Also, having information SAVED ON A COMPUTER rather than written on something will help with the chances of NOT LOSING the information. Ability to SHARE the information Ability for MORE THAN ONE PERSON to work on it Fewer inconsistencies in data / reduces redundancies *

* 07/16/96 Database MODELS According to Wikipedia: A database model is the THEORETICAL foundation of a database and fundamentally determines in which manner data can be stored, organized, and manipulated in a database system. It thereby defines the infrastructure offered by a particular database system. Simply put, a database model determines HOW data is STORED and ORGANIZED *

Database Model – Relational * 07/16/96 Database Model – Relational RELATIONAL database model is the most common Composed of tables, each constructed like a flat file Click here to open an Excel file which illustrates Flat files *

What are Tables or Entities? * 07/16/96 What are Tables or Entities? TABLES (aka “ENTITIES”) in the relational model are used to represent "things" in the real world. ENTITIES are made up of ROWS and Columns. Columns are called fields or attributes. ROWS are called RECORD Within a table, each ROWS is called a RECORD and it represents 1 particular instance of its entity, not unlike the flat file. *

What is a Primary Key? * 07/16/96 A FIELD in the database that guarantees UNIQUENESS SPEEDS data RETRIEVAL Each RECORD in a table must have a PRIMARY KEY Each PRIMARY KEY is the 1ST attribute (column) listed *

* 07/16/96 What are Foreign Keys? A FOREIGN KEY is used to indicate a relationship between 2 or more TABLES Each FOREIGN KEY is a PRIMARY key in another table *

Create relationships In MS ACCESS

Create Relationships DATABASE TOOLS ribbon > RELATIONSHIPS grouping

“Enforce Referential Integrity” A system of rules that MS Access uses to ensure that relationship data is valid and that you CANNOT ACCIDENTALLY DELETE a record in 1 table if a matching record is present in a related table. You can NOT set “Referential Integrity” unless the MATCHING field from the PRIMARY table is a primary key The related fields must have the same Data TYPE http://www.ehow.com/how_13625_understand-referential-integrity.html

ASSIGNMENTS-BE CAREFUL WHEN DOWNLOADING “CHEATING” possibilities BE CAREFUL when you are DOWNLOADING your assignment files.  When you DOWNLOAD them, the files come with an embedded ENCRYPTION code IF you COPY THE FILE from another student, your assignment will be flagged with a “POTENTIAL INTEGRITY VIOLATION”,(cheating). EVEN IF YOU SEND AN UNedited file, you may be legitimately doing your own work, but, the file has the ENCRYPTION code your assignment will be flagged with a “POTENTIAL INTEGRITY VIOLATION”,(cheating).

ASSIGNMENTS—READ INSTRUCTIONS VERY, VERY CAREFULLY!! You have to be very, very careful with ALL the components in myitlab.  The software is extremely specific—it IS case-sensitive, and if you add a space where there shouldn’t be (or vice versa), or forget to include a punctuation mark (or vice versa), myitlab will mark it wrong.  When you do your assignments, you must read the instructions extremely carefully, not “skimming over” any of the instructions, just in case you miss a tiny requirement. 

PRINT OUT ASSIGNMENT MARKS Please make sure that as soon as you get your MARK  for ANY assignment, that you do the following: DO NOT CLOSE the dialog box with your mark on it--before doing the following: 1.       Hit your PRINT SCREEN button on your keyboard 2.       Open MS WORD 3.       PASTE 4.       Enlarge the “screen capture”, so that it’s readable 5.       PRINT out your MARK, AND SAVE the file to the DESKTOP -then UPLOAD the file to SkyDrive 6.       You may now close the dialog box. There have been some students who have gotten their mark, but when they close the dialog box with the mark on it-- they receive a “0” in their GRADEBOOK. (This is the mark that I see). This “print out” will be your backup copy—put it in a safe place, until the end of the semester.

SUBMITTING ASSIGNMENTS: 3 STEPS * 07/16/96 Click on: “Upload Completed Assignment” Navigate to where your completed assignment file is, double-click on the file, and then click on: “Upload” *
