• Modify Access views and behaviors
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 4
Compact and Repair a Database
• Database files should be rebuilt routinely– Ensures optimal performance
• Database file size increases rapidly– Especially as forms, queries, or reports are
modified or deleted– Database file size does not decrease when
objects or records deleted
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 5
Compact and Repair a Database
• Compact & Repair– Process in which an Access file is rewritten– Stores objects and data with less wasted
space
• Access database files commonly measured in bytes
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 6
Compact and Repair a Database
• A byte typically stores a single character– Such as a digit or a letter
• Bytes used to measure– Storage sizes on disks– Computer memory
• A kilobyte (KB) stores 1,024 bytes
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 7
Compact and Repair a Database
• When an Access database is opened– A temporary file is opened
• When an Access database is closed– The temporary file is deleted
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 8
Back Up a Database
• Data loss is the unexpected failure of information
• Data loss caused by such actions as– Hardware malfunction– Accidental deletion of records– Theft– Natural disaster
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 9
Back Up a Database
• Lost data often recovered through copy of database
• Backing up is the process of creating a copy of a file or files
• Organizations typically make backups daily
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 10
Back Up a Database
• Backing up files also done– Before making database design changes– Before performing maintenance tasks
• Collection of backup copies used– To recover data– To provide a historical record of transactions
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 11
Back Up a Database
• Backup is a copy of an original file– Should be stored in an alternative location
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 12
Back Up a Database
• Storing backup copies on same computer:– NOT recommended– Can result in loss of both original and
backup after data loss event
• Store backup copies in different location from original– Can be stored on removable media
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 13
Convert Databases to an Earlier Version of Access
• Microsoft Access 2010 supports different database formats
• Database file formats supported by Access 2010– Prior to 2002-2003 file format– 2002-2003 file format– 2007 file format
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 14
Convert Databases to an Earlier Version of Access
• If version of database file is prior to Access 2002-2003 format– Must be converted to Access 2010 format
to open– Features found only in prior version will not
be supported by Access 2010• Convert to Access 2002-2003 format if earlier
features needed
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 15
Convert Databases to an Earlier Version of Access
• If version of database file is Access 2002-2003– Features supported by Access 2002-2003
added to Ribbon
• If version of database file using features new to Access 2007 or 2010– Database cannot be converted to 2002-
2003 format
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 16
Convert Databases to an Earlier Version of Access
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 17
Convert Databases to an Earlier Version of Access
• Application title bar displays Access file format used
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 18
Replicate and Synchronize a Database
• Replica is a special copy of a database– Any changes made in replica database
sent to original database and any other replicas
• Replication is a process of creating a replica
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 19
Replicate and Synchronize a Database
• Replication enables several users to work with a database without connecting to organization’s network– Can send changes to the master (original)
database when do connect to original database
• Replication supported by 2002-2003– Not supported in Access 2007 or 2010
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 20
Replicate and Synchronize a Database
• Replica set composed of original database and all replicas– Design Master is the original database in
replica set– Design changes made in Design Master
only– Changes made to Design Master passed
on to each replica
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 21
Use Microsoft Access Analysis Tools
• Table Analyzer searches for repeated data in table– Then splits the table into two or more
tables• Tables smaller and related
– Avoids redundancy
• Table Analyzer Wizard used to split tables
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 22
Use Microsoft Access Analysis Tools
• Performance Analyzer used to identify and fix database problems
• Performance Analyzer Wizard– Analyzes database objects– Offers suggestions for object improvement
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 23
Use Microsoft Access Analysis Tools
• Indeterminate relationship between two tables– Does not enforce referential integrity
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 24
Use Microsoft Access Analysis Tools
• Performance Analyzer provides three levels of suggestions– Recommendation– Suggestions– Ideas
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 25

• Performance Analyzer dialog box
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 26
Use Microsoft Access Analysis Tools
• Dependencies between objects– Shown in Object Dependency pane
• A dependency is where– An object requires another database object
OR– An object depends on another database
object
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 27
Use Microsoft Access Analysis Tools
• Dependency example– Several queries may depend on a single
table
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 28
Use Microsoft Access Analysis Tools
• Database Documenter builds a report– Contains detailed information about all
database objects
• Data dictionary is the report created– Should be printed periodically– Saved in a safe place– Displays report in Print Preview
with Microsoft Access 2010 © 2011 Pearson Education, Inc. Publishing as Prentice Hall 29
Add Action Tags
• Action tags enable Access integration to another program– Can perform tasks in Access without
opening the other program– The other program used, like Outlook,
must be installed on computer
