Lab Overview
You have been asked to extend the database you developed in Lab 2 to also include customer data, to populate the tables in the database with sample data, and to create some queries using this data to illustrate how the database can supply information that is useful to management. The purpose of this lab is to provide experience with modifying a database, entering data into tables, and creating simple queries.
Using MS Visio, you will add a customers entity to the ERD you created in Lab 2. Based on the modified ERD, you will add the corresponding customers table to the MS Access database from Lab 2. You will then enter sample data into the tables in this database and create some basic queries to illustrate how data from the tables can be presented to satisfy managers’ information needs.
Upon completing this lab, you will be able to
- Modify an existing MS Visio ERD to include new entities and relationships;
- Modify an existing MS Access database to include new entities and relationships;
- Enter data into tables in a MS Access database using datasheet view; and

Scenario/Summary
We can collect all the data in the world, however, if we can’t access it and use it, it is probably useless. Gaining knowledge from stored data can be very beneficial when it comes to making important business decisions. This lab will give the student practice in querying or questioning data. The lab begins with a simple example of query development using Access, then evolves to more complex queries, which the student should perform after completing the first exercise. The student can create a query with the wizard, or with query design view.
Upon completing this lab, you should be able to:
- create a query by following lab instruction;
- create a query by using either Query Designer or Query Wizard; and
- interpret the results of queries.
Deliverables

Lab Overview
The purpose of this lab is to show the student how to create navigation systems for an Access application. Students will create a main navigation form, which links to additional navigation forms called enter data and view reports. Additionally, students will create forms to automate printing reports and closing or exiting the database. The enter data form allows you to open customer and city forms automatically. The view reports form allows the user to automatically open the customer list and customers by city reports. The print reports form will allow users to automatically print the reports. The exit database form allows users to close the database and exit the application entirely.
The navigation forms can provide some measure of security to the database as they may prevent users unfamiliar with Access from entering database objects directly. They make using Access more intuitive to use and can prevent new users from inadvertently damaging your database objects.
Deliverables
Submit the modified Lab7_Start.accdb file that you saved as YourName_Lab7.accdb to the Week 7 Lab for grading.
Part A: Develop the enter data, view reports, print reports, and customer database navigation forms.
Part B: Create the close database form and add it to the main database navigation form. Set the database options.

Gathering Requirements and Choosing Database Solution
Week 1 All Students Posts – 61 Pages
Click Here: BIS245 Course Discussions Week 1
- Why are databases important to business? How do databases generate sales and profits? What databases do you interact with, and how do they benefit you?
- What is meant by requirements gathering, and why is it important to clearly define the data requirements of a database before creating it?
- Microsoft Access is one of the most popular database platforms on the market. However, there are many competitors. Why do you think that Access is so popular? What are some of the other types of databases available?
- Do you think that Access can serve as a corporate database solution, or is it strictly a personal database solution? What might be the difference between a personal and corporate database solution?
Databases are important because they efficiently manage data and allow users to perform multiple tasks easier. They also manage and store data in one place. Databases do not…
A database is a collection of data that is organized. This collected data is easily accessed, managed, and updated. Self-describing collection of integrated records means that there is a dictionary of data that contains the information stored in the database and the description of the database. This means that the data and description of data are stored together and creates data independence. Integrated records are records that are grouped together in columns or fields then in turn, are grouped into rows…

Applying Design to Entity Relationship (ER) Modeling
Week 2 All Students Posts – 71 Pages
Click Here: BIS245 Course Discussions Week 2
- When designing database tables, the difference between a good design and a bad design can be a few seconds in response time and several minutes. You may think that this is not a huge difference, but imagine waiting several minutes on a web page for your results to load. How long would you wait? A slow database can mean the loss of customers. So let’s begin by discussing some of the common elements of tables and how you would approach the table design. What would you do to ensure that your page loads in a few seconds? Discuss the relationship types and how they affect your design.
- What role does the entity-relationship (ER) diagram play in the design process? Discuss the different types of information represented in the ER diagram and the symbols used to represent them. How would you approach the diagramming process?
Data modeling is taking all of the main points in your data and putting them together to explain what you are trying to show. I believe that data modeling is really like a book, because you are basically telling some kind of story behind your data. So in other words data modeling really is creating something that makes it easy for people to understand what you are showing. If this is done right then others can use your information that was gathered to find what they are looking for. A good example might need to find out what a customer bought and when they bought it…

Requirements Analysis and Conceptual Design
Week 3 All Students Posts – 62 Pages
Click Here: BIS245 Course Discussions Week 3
- Describe some typical pairs of entities that you think might be common in business, and describe their relationships, whether many-to-many, one-to-many, many-to-one, or one-to-one. Explain why you think that a particular relationship applies to that pair of entities.
- Why do you think organizing data into tables and relationships is a good way to design a database? How do related tables improve the accuracy of data in a database?
Physical ERD represents the actual design blueprint of a relational database. It represents how data should be structured and related in a specific DBMS so it is important to consider the convention and restriction of the DBMS you use when you are designing a physical ERD. This means that an accurate use of data type is needed for entity columns and the use of reserved words has to be avoided in naming entities and columns. Besides, database designers may also add primary keys, foreign keys and constraints to the design…

Creating Queries From Woodcraft Database
Week 4 All Students Posts – 52 Pages
Click Here: BIS245 Course Discussions Week 4
- What kinds of queries would be useful to Woodcraft, assuming that it wants to improve its sales, relationship with its customers, or other aspects of its business? Describe what information you might want to select from the database in the form of a query, and list the specific columns and data that the query would produce. Assume that they have hundreds of customers, rather than the short list found in the database file.
- Suggest additional tables and information that you would like to see in a database like this, the kinds of queries that it would facilitate, and how such queries would help the company improve its business goals of profitability, cost reduction, or other business strategies.
- Using the Woodcraft database file, create some queries that use concepts found in the textbook, as well as this week’s lab. Post a screenshot of your query design and result set in a Word document.
- Research one new feature that you haven’t studied as it relates to query generation, and show how you could use that feature to create a useful query. Use the Woodcraft database to showcase this query-generation technique and post it in this discussion.
My opinion is that google is like a query as to how when you type in what you want to search it breaks it down to your criteria. Using query you can tell it what you want to look for like, who, what, when and where of just exactly what you want to find easily by narrowing down your search. So when you go to google to search for a specific thing you can make it do the exact same thing as a query…

- How do you recognize the difference between good and bad structures? What role does normalization play in good and bad table structures, and why is normalization so important to a good table structure?
- What is the importance of data validation, and how can user data entry errors be reduced or eliminated?
Normalization would be the way you organize data that is in a database. This is needed when you need to save any kind of space on any kind of data storage. A good example of a storage area would be possibly a disc or even a thumb drive. This allows for more area and also increases the speed of the performance…

Presenting and Reporting Data
Week 6 All Students Posts – 52 Pages
Click Here: BIS245 Course Discussions Week 6
- Database reports provide us with the ability to further analyze our data, and provide it in a format that can be used to make business decisions. Discuss the steps that you would take to ensure that we create an effective report. What questions would you ask of the users?
- Data presentation should be designed to display correct conclusions. What issues should we think about as we prepare data for presentation? Discuss the different methods that we can use to present data in a report. What role does the audience play in selecting how we present the data?
I would ask if there was any specific thing that they would like to see the characteristics of. I would also ask if we are looking for total products or total sales totals or just how many of each was sold for the year, for the month. There are so many variables when it comes to creating a report. There are also a ton of options in most cases to get what the end user wants. This is why it is so important to put your data in correctly, so that you will be accurate with any reports that need to be generated…

Database Navigation and Data Security
Week 7 All Students Posts 47 Pages
Click Here: BIS245 Course Discussions Week 7
- Finding information in a database can be difficult unless you know what information you need and how to look for it. Creating a navigation system or menu allows Access to act like a point-and-click system. What are some of the types of navigation that you can create in Access 2016? How should we approach the design of the menu?
- Why is data security important now more than ever? What are some of the steps that we can take to ensure that our database is protected and secure? How can you use user views to enhance security and restrict access?
Pros
- Tab based navigation allows you to present more content to the user in a limited space.
- Probably useful for mobile devices where you do not have much screen real estate.
- On desktop browsers, as soon as content for active tab is fetched from server, it can be displayed to the user. Rest of the tabs can be loaded on demand using ajax when the user navigates to them or can be pre-fetched in the meantime the user is going through the active tab. This provides a good user experience as data is quickly available to the user.
Cons
- Content from multiple tabs cannot be viewed at once. Tab navigation should never be used when there is a use case where user may need to view/compare data from multiple tabs.
One limitation I see in using tabbed navigation on mobile devices is that the tab links can take up a large portion of the screen which could have been used otherwise…
