3. Define many-to-many and one-to-one relationship between table
4. View and create indexes for tables
5. Learn about joining tables
6.  Join a table using a self-join
 

Important Points.
1. An acton query is a query that adds, changes, or deletes multiple table records at one time.
2. A make-table query creates a new table from one or more existing tables.
3. An append query adds records from an existing table or query to the end of another table.
4. A history table contains data that is no longer needed for current processing but that you might need to reference in the future.
5. A delete query deletes a group of records from one or more tables.
6. An update query changes selected fields and records in one or more tables.
7. Advanced Filter/Sort lets you specify multiple selection criteria and specify a sort order for the selected records in the filter window.
8. A one to many relationship exists between two tables when each record in the primary table matches zero, one, or many records in the related table, and when each record in the related table matches exactly one record in the primary table.
9. A many to many relationship exists between two tables when each record in the first table matches many records in the second table, and each record in the second table matches many records in the first table.
10. A one to one relationship exists between two tables when each record in the first tables matches at most one record in the second table, and each record in the second table matches at most one record in the first table.
10a. One to one, one to many and many to many are global joins that are active when the database is loaded.
11. An entity subtype is a table whose primary key is a foreign key to a second table and whose fields are additional fields from the second table.
18. An index is a list that relates field values to the records that contain those field values.
19. An inner join is a join in which Access selects records from two tables only when the records have the same value in the common field that links the tables.
20. A left outer join is a join in which access selects all records from the first, or left, table and only those records from the second, or right table that have matching common field values.
21. A right outer join is a join in which Access selects all records from the second, or right, table and only those records from the first, or left, table that have matching common field values.
22. A self-join is join a table with itself
22a. inner join, left outer, right outer and self join are local joins and are only loaded when the query is run.
23. An index is a list that relates field values to the records that contain those field values.
24. Indexs can be viewed in the table design view.

5. Compile and test function procedures, Sub procedures, and event procedures
6. Hide text and change display colors
7. Create event procedures for a dialog box.

Important Points.
1. Visual Basic for Applications is a programming language that only compiles within the application. A separate compiled executable file is not created outside of the application (access).
2. Coding is the process of writing VBA instructions.
3. VBA instructions are called statements that respond to events that occur with the objects in a database.
4. VBA is called both an event-driven language and an object-oriented language.
5. An event property specifies how an object responds when an even occurs.
6. An event procedure occurs when access executes (calls) a group of statement when an event occurs.
7. Function procedure, or function, performs operations, returns a value, can accept input values, and can be used in expressions.
8. Sub procedure, or subroutine,performs operations and can accept input values, but does not return a value and cannot be used in expressions.
9. You store a group of related procedures together in a module.
10. Each module starts with a Declarations section, which contains statements that apply to all procedures in the module.
11. A standard module is a database object that is stored in memory with other database objects when you open the database.
12. A procedure that more than one object can use is called a public procedure.
13. A class module is usually associated with a particular form or report.
14. The event procedures in a class module are local procedures, or private procedures, which meant that only the form or report for which the class module was crated can use the event procedure.
15. Focus refers to the record and control that is currently active and awaiting user action.
16. The Current event occurs when a form opens and when the focus moves to another record, the VBA procedure is associated as an event procedure with the form's OnCurrent Property.
17. The Visual Basic Editor is the program you use to create and modify VBA code.
18. The Visual Basic Window is the program window that opens when you use VBA.
19. The Code window is the window in which you create, modify and display VBA code.
20. All event procedures are Sub procedures.
21. Each sub procedure begins with a Sub statement and ends with an End Sub statement.
22. The sub statement includes the scope of the procedure, the name of the procedure, and an opening and closing parenthesis.
23. The Option Compare statement designates the technique Access uses to compare and sort text data.
24. A control structure is a set of VBA statements that work together as a unit.
24a. Case control structure is a conditional control structure which evaluates an expression.
25. An assignment statement assigns the value of an expression to a field or property.
26. A field's ForeColor property determines the field's foreground, or font color.
26a. The RGB (RED,GREEN,BLUE) function returns an RGB color value.
Hyper Links: For 3 number color codes:

http://www.lynda.com/hexh.html

27. The Visible property determines when Access displays a control.
28. The AfterUpdate event simply accepts the new or changed entry into a field.
29. Each function begins with a function statement and ends with an End Functions statement.
30. A placeholder is called a parameter.
31. The value passed to the function and used in place of the parameter when the functions is executed is called an argument.
32. All VBA function names, Sub procedure names, argument names, and other name you create must conform to the following rules:

a. Must begin with a letter
b. Cannot exceed 255 characters
c. Can include letters, numbers, and the underscore.
d. Cannot contain keywords that VBA uses as part of its language.
e. Must be unique.

33. The UCase function accepts a single string argument as input, converts the value of the argument to uppercase letters, and then returns the converted value.
34. A logic error occurs when the procedure produces incorrect results.
35. Use the Immediate window to test VBA procedures without changing any data in the database.
36. An If statement executes one of two groups of statements based on a condition being true or false.
36a. True-statement group is the code that is executed when the condition is true.
36b. false-statement group is the code that is executed when the condition is false.
37. The IsNull function returns True when a filed value is null and false when it is not null.
38. The process of translating modules from VBA to machine language is call compilation. The module is compiled.

9. Encrypt and decrypt a database
10. Set and unset a database password
11. Use the User-Level Security Wizard to assign users, groups, and permissions to a database
12. Create an MDE file

Important Point:
1. The Performance Analyzer is an Access tool that you can use to optimize the performance of an Access database.
2. The Documenter is used to print out the characteristics of the database.
3. A linked table is a table that is stored in a file outside the open database from which Access can update and retrieve records in the open database.
4. The database can be linked to data stored in Excel, HTML documents, text files, other Access databases, and databases created by other DBMS.
5. The Linked Table Manager is an Access tool you use to change the filename or disk location for linked tables in an Access database.
6. If you change a linked files location you must refresh the link.
7. When you create a replica of a database, the original copy of the database becomes the Design Master.
8. The design Master and all of its replicas are called the replica set.
9. The process of updating the Design Master and the replicas is called synchronization.
10. Replica priority refers to when multiple replicas update the same record, only the change for the replica with the highest priority is made.
11. Replica visibility choices are global, local, and anonymous.
12. The replica record deletion when checked prevents a user from deleting a record in the replica.
13. The Database Splitter is an Access tool that splits an Access database into two files: one file contain the tables, and the other contains the queries, forms, and other database objects.
14. The database that contain the tables is called the back-end database.
15. The database that contains the other objects if called the front-end database.
16. Startup options take place when a database opens.
17. Security refers to the protection of a database against unauthorized access, either intentional or accidental.
18. Encryption converts the data in a database to a format that's indecipherable to a word processor or other program and stores it in a encrypted format.
19. Decryption a database reverse the encryption.
20. A password is a string of characters assigned to a database that users must enter before they can open the database.
21. When you open a database with exclusive access, you prevent other users from opening and using the database at the same time. When you set a password open the database up with exclusive access.
22. User-level security lets you grant users or groups of users specific permissions to tables, queries, forms, reports, and macros.
23. A user's permissions specify what kind of access the user has to objects in a database.
24. User permissions are Modify Design, Read Data, and Delete Data.
25. The database administrator controls the permissions assigned to database users.
25a. User-lavel security wizard is used to create the workgroup information file and establish groups, users, and their permissions.
26. A group is a collection of users identified by a group name and ID.
27. Group name and IDs, user names and passwords, and group membership information are stored in an Access Workgroup information file that is read at startup.
28. The users group is one of two groups created by default when you create a new workgroup information file.
29. Users assigned to the Admin group have full permissions and are the only users that can create users and groups.
30. A MDE file complies all VBA modules, removes all editable VBA source code, and compacts the resulting database.
31. You can't view, modify, or create forms, reports, or modules in Design view, and you can"t import or export forms, reports, or modules in a MDE file.
