Are you a lone electronic resources librarian at a small institution? Are you unable to implement an electronic resource management (ERM) system due to lack of financial or technical resources? Is your administrative information for e-resource subscriptions still recorded in a variety of physical print-outs, Word documents, Excel spreadsheets, staff wiki pages, etc., and you would like to organize it in one central location? Then this is the session for you! This program will describe the presenter's step-by-step approach to creating a homegrown electronic resources management (ERM) system using Microsoft Access 2010. The topics covered will include use-case analysis, data analysis, card sorting for database design, tables and relationships in databases, and how to use forms in Access to make the ERM database user-friendly. The presenter will also refer to free, online Access 2010 documentation that was referenced in the creation of her local ERM system. Presenter: Sarah Hartman-Caverly
Electronic Resources Manager, Delaware County Community College

  • NEXT: DATABASE DESIGN TOOLSQuestions or comments?
  • Database Design ToolsThree principles of goodsystem design*:• Minimize user effort• Minimize user error• Maximize user output*(Recall my disclaimers!)CC Photo Attribution: cell105 via Flickr
  • Database Design Tools• Use case analysis• What do the users need to accomplish with the system?• Forms in MS Access• How can I make the system more user-friendly?• Card sorting• How do the users expect data to be stored (structured)?• Tables and relationships• How will that data be stored (structured)?• Data analysis• What data does the system need to store?
  • Use Case Analysis• Step-by-stepnarrative describinguser interactions withthe systemDennis, A. et al. (2012). System analysis and design.• From the users’perspective• Each use case isbased on a user goal• Event-driven model• Shows user-triggeredevents and expectedsystem responses
  • Use Case AnalysisComponents:• Actors (user(s) and system)• Trigger• Preconditions• Normal course• Alternate Courses• Postconditions• Exceptions• Summary:• Inputs and their Sources• Outputs and their DestinationsDennis, A. et al. (2012). System analysis and design.
  • Use Case Analysis• Provides real usescenarios for systemtesting Dennis, A. et al. (2012). System analysis and design.• Reveals most (if not all)functional requirements• Helpful in understandingexceptions, specialcases, and error handlingrequirements• Helpful in prioritizingfeatures and functions fordevelopment
  • Use Case Analysis: How to…Identify use cases• Ask:• Identify:Dennis, A. et al. (2012). System analysis and design.• Who? (users)• What? (goal)• When? (trigger)• How? (user-system interactions)• Main user tasks• Triggers for these tasks
  • Use Case Analysis: How to…Identify steps within ause case• Ask:• Identify:Dennis, A. et al. (2012). System analysis and design.• How does the work getdone?• How does the system getthe inputs it needs?• How does the user get theoutputs zhe needs?• Preconditions• User events• System responses
  • Use Case Analysis: How to…Identify elements withineach use case step• Ask:• Identify:Dennis, A. et al. (2012). System analysis and design.• What information doesthe user know (can theuser input)?• What information doesthe system know (can thesystem output)?• Preconditions• (User) Inputs• (System) Outputs
  • Use Case Analysis: How to…Validate the use case• Ask:• Techniques:Dennis, A. et al. (2012). System analysis and design.• What exceptions orspecial cases (alternatecourses) might come upfor this use case?• Is the user able to meetzher goal?• Role playing• Focus groups• Interviews• Workshops
  • Use Case AnalysisWhat are some examples of use cases ine-resources management?Renewing a subscriptionReporting/tracking an accessproblem
  • NEXT: DATA ANALYSISQuestions or comments?
  • Data AnalysisEntity-RelationshipDiagram (ERD)• Shows types ofinformation in thesystem and how theyare organized andrelated to each other• Still from the users’perspective Dennis, A. et al. (2012). System analysis and design.
  • Data AnalysisERD Components:Dennis, A. et al. (2012). System analysis and design.• Attributes – informationabout entities (nouns)• Relationships –associations betweenentities (verb)• Entities – person, place,event, or thing (nouns)
  • Data AnalysisERD Relationships• Show high-levelbusiness rules orlogicDennis, A. et al. (2012). System analysis and design.• Directionality ofrelationships betweeninformation• Cardinality ofrelationships betweeninformation• Modality of relationshipsbetween information
  • Data AnalysisERD Relationships, cont’d.• Directionality• Cardinality• Modality Dennis, A. et al. (2012). System analysis and design.• 1:1 (one-to-one)• 1:N (one-to-many)• M:N (many-to-many)• 0 (not required; may be null)• || (required)• Parent entity is usually:• The 1-side entity in a 1:Nrelationship• The ||-side entity in arelationship
  • Data Analysis: How to…Identify entitiesDennis, A. et al. (2012). System analysis and design.• Document analysis• Look for key nouns inyour existing ERMdocumentation(spreadsheets, licensefiles, e-mail, etc.)• Use case analysis• Identify key nouns inyour use cases
  • Data Analysis: How to…Identify entity attributesDennis, A. et al. (2012). System analysis and design.• More document analysis• What information aboutentities do you alreadymaintain?• What piece of informationuniquely identifies eachinstance of an entity (ifany)?• More use case analysis• What are the user inputs andsystem outputs?• What entities are theseinputs and outputs about?
  • Data Analysis: How to…Identify and modelentity relationships• Ask:Dennis, A. et al. (2012). System analysis and design.• How are entities associatedwith each other (in real life)?• How many instances of eachentity can participate in therelationship (cardinality)?• Can an instance of either entityin the relationship exist withoutan instance of the other entity(modality)?• Which entity acts on the otherin the relationship(directionality)?
  • Data Analysis: How to…Identify and model entityrelationships, cont’d.• NormalizationNow we are really in theweeds of database design!Dennis, A. et al. (2012). System analysis and design.• Usually reconfigure M:Nrelationships with an „intersection(or associative) entity‟ which hasa 1:N relationship with eachoriginal entity• 3 Levels of Normalization• 1NF: Remove redundant attributes• 2NF: Split off attributes that apply tomore than one entity into their ownentity• 3NF: Split off attributes that are notdependent on the unique identifierinto their own entity
  • Data AnalysisWhat are some examples of entities ine-resources management?PackagesPlatformsDatabases/E-Resources
  • NEXT: TABLES ANDRELATIONSHIPS IN DATABASESQuestions or comments?
  • Tables and RelationshipsWhat’s the point?• Avoid duplicate orredundant datastorage• Store each piece of informationonce!• Relationships betweentables in [relational]databases allow tables to‘share’ information theyhave in commonCC Photo Attribution: PhotoCo. via Flickr
  • Tables and Relationships• Identifiers becomeprimary keys – amandatory, uniquevalue for each record(instance) in the table(of an entity)• Primary keys can alsobe system-generated• Entities becometables• Attributes becomefields
  • Tables and Relationships• Primary keys of parententities becomeforeign keys of childentities• Creates a commonfield (attribute)between the tables(entities)• But you only have tostore the data once!• Instantiates therelationship betweenthe tables (entities) inthe database
  • Tables and RelationshipsWhat are some examples of entity relationshipsin e-resources management?• Which is the parent and which is the child entity?• What kind of identifier could serve as theprimary/foreign key?Vendor || [1]  Subscription 0 [N]• Vendor_ID (EIN or system-generated)Package 0 [1]  E-Resource || [N]• Package_ID (vendor-specified or system generated)
  • NEXT: CARD SORTINGQuestions or comments?
  • Card Sorting• User-centered techniquefor designing informationarchitecture• Quick, inexpensive,inclusive• Aids in discoveringentities and theirattributesCC Photo Attribution: Rosenfield Media via Flickr.
  • Card Sorting• Cards representingpieces of information aresorted by users intocategories that makesense to themCC Photo Attribution: Rosenfield Media via Flickr.• In theory, each card isa potential attributeand each user-createdcategory is a potentialentity• (Can be done online!)
  • Card Sorting: How to…Prepare a card sort:1. Select content2. Select participants3. Prepare cards (or onlinesort)CC Photo Attribution: Rosenfield Media via Flickr.• Be consistent with the levelof granularity• Document/use case analysis• May be done individually orin a group• Who will use your system?• Label each card; providebrief description if necessary• 30-100 items works well
  • Card Sorting: How to…Execute a card sort:1. Randomize cards2. Introduce activity andprovide basicinstructions3. Moderate participantsas they perform the sort• Answer questions but don’t leadparticipants4. Record resultsCC Photo Attribution: Rosenfield Media via Flickr.
  • Card Sorting: How to…Analyze card sortresults:1. Look for broad trends,and/or2. Use cluster analysissoftware• Online card sortprovides thisCC Photo Attribution: Rosenfield Media via Flickr.
  • Card Sorting: How to…Perform an onlinecard sort:• WebSort.net• Free study for up to10 participants• (Can be upgraded)
  • Card Sorting: How to…Analyze an onlinecard sort:• WebSort.net• Categories x Itemsreport under Results• Exportable to Excel
  • NEXT: FORMS IN MS ACCESSQuestions or comments?We’re in the homestretch!
  • Forms in MS AccessDisplay and edit information in a user-friendly wayBefore:After:
  • Forms in MS Access: How to…Create a Form• Establish tables, tablerelationships, andqueries first• Fields available in Formview are determined bytables and theirrelationships• Easiest method:1. Select the Table orQuery in the navigationpane2. Select Form under theCreate toolbar ribbon
  • Forms in MS Access: How to…Create a Form,cont’d.• Forms are available in avariety of formats andfeatures• Advice:1. Create TWO back-upcopies of your database• 1 is a true back-up copy• 1 is a ‘sandbox’ for youto play and experimentin2. Become friends withyour IT department!
