with Microsoft Access 2010© 2011 Pearson Education, Inc. Publishing as Prentice Hall1 PowerPoint Presentation to Accompany GO! with Microsoft ® Access 2010 Chapter 10 Administering Databases

with Microsoft Access 2010© 2011 Pearson Education, Inc. Publishing as Prentice Hall2 Objectives Compact and repair a database Back up a database Convert databases to an earlier version of Access Replicate and synchronize a database

with Microsoft Access 2010© 2011 Pearson Education, Inc. Publishing as Prentice Hall3 Objectives Use Microsoft Access analysis tools Add Action Tags Modify Access views and behaviors

with Microsoft Access 2010© 2011 Pearson Education, Inc. Publishing as Prentice Hall4 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 Hall5 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 Hall6 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 Hall7 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 Hall8 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 Hall9 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 Hall10 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 Hall11 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 Hall12 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 Hall13 Convert Databases to an Earlier Version of Access Microsoft Access 2010 supports different database formats Database file formats supported by Access 2010 –Prior to file format – file format –2007 file format

with Microsoft Access 2010© 2011 Pearson Education, Inc. Publishing as Prentice Hall14 Convert Databases to an Earlier Version of Access If version of database file is prior to Access 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 format if earlier features needed

with Microsoft Access 2010© 2011 Pearson Education, Inc. Publishing as Prentice Hall15 Convert Databases to an Earlier Version of Access If version of database file is Access –Features supported by Access added to Ribbon If version of database file using features new to Access 2007 or 2010 –Database cannot be converted to format

with Microsoft Access 2010© 2011 Pearson Education, Inc. Publishing as Prentice Hall16 Convert Databases to an Earlier Version of Access

with Microsoft Access 2010© 2011 Pearson Education, Inc. Publishing as Prentice Hall17 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 Hall18 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 Hall19 Replicate and Synchronize a Database Replication enables several users to work with a database without connecting to organizations network –Can send changes to the master (original) database when do connect to original database Replication supported by –Not supported in Access 2007 or 2010

with Microsoft Access 2010© 2011 Pearson Education, Inc. Publishing as Prentice Hall20 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 Hall21 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 Hall22 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 Hall23 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 Hall24 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 Hall25 Use Microsoft Access Analysis Tools Performance Analyzer dialog box

with Microsoft Access 2010© 2011 Pearson Education, Inc. Publishing as Prentice Hall26 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 Hall27 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 Hall28 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 Hall29 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

with Microsoft Access 2010© 2011 Pearson Education, Inc. Publishing as Prentice Hall30 Add Action Tags Action Tags dialog box

with Microsoft Access 2010© 2011 Pearson Education, Inc. Publishing as Prentice Hall31 Modify Access Views and Behaviors Access has many options –Affect database views and behaviors Options changed through Access Options dialog box –How windows displayed –How text is formatted –Many more options
