Bonus Base Project: Building a CRM System for Managing Customer Data and Interactions

In this intermediate project, we’ll guide you through creating a Customer Relationship Management (CRM) database using LibreOffice Base. A CRM database helps you store and manage customer information, track interactions and generate reports that give you insight into customer activity. Whether you’re a small business owner or part of a larger organisation, this project will provide the foundation for effectively managing your customer relationships.

By the end of this project, you’ll have a functioning CRM system that can be expanded to suit your needs.

Step 1: Planning the CRM Database Structure

Before we create the database, we need to define the key tables and fields that will store the customer data and interaction logs.

Key Tables

1. Customers:
   • Stores basic customer information, such as CustomerID, FirstName, LastName, Email and PhoneNumber.
2. Interactions:
   • Logs all interactions with customers, including the InteractionID, CustomerID (foreign key from the Customers table), InteractionDate and InteractionDetails.

Step 2: Creating the Customers Table

Let’s start by creating the Customers table to store key customer information. This table will serve as the backbone of your CRM system.

Step-by-Step: Creating the Customers Table

1. Open LibreOffice Base:
   • Create a new database by going to File > New > Database. Select Create a new database and click Finish.
2. Go to Table Design:
   • In the Database Pane, click on Tables and then Create Table in Design View.
3. Define the Fields:
   • Add the following fields:
     • CustomerID (Integer): Primary key, auto-increment.
     • FirstName (Text): Customer’s first name.
     • LastName (Text): Customer’s last name.
     • Email (Text): Email address.
     • PhoneNumber (Text): Phone number.
4. Set the Primary Key:
   • Right-click the CustomerID field and select Primary Key.
5. Save the Table:
   • Click Save and name the table Customers.

Step 3: Creating the Interactions Table

Next, we’ll create a table to log customer interactions. Each interaction will be linked to a customer using a foreign key relationship.

Step-by-Step: Creating the Interactions Table

1. Open Table Design:
   • In the Tables section, click Create Table in Design View.
2. Define the Fields:
   • Add the following fields:
     • InteractionID (Integer): Primary key, auto-increment.
     • CustomerID (Integer): Foreign key, links to the Customers table.
     • InteractionDate (Date): Date of the interaction.
     • InteractionDetails (Text [Memo]): A longer text field to store details of the interaction.
3. Set the Primary Key:
   • Right-click the InteractionID field and select Primary Key.
4. Save the Table:
   • Click Save and name the table Interactions.

Step 4: Establishing Relationships Between Tables

Now that the tables are created, it’s time to link them. The CustomerID field in the Interactions table will reference the CustomerID field in the Customers table. This relationship allows you to log multiple interactions for each customer.

Step-by-Step: Defining Table Relationships

1. Open the Relationships Window:
   • Go to Tools > Relationships.
2. Add Tables to the Relationship Window:
   • Click Add Tables and add both the Customers and Interactions tables.
3. Create the Relationship:
   • Click and drag the CustomerID field from the Customers table to the CustomerID field in the Interactions table.
4. Enforce Referential Integrity:
   • In the Relationship dialog, check Update Cascade and Delete Cascade. This ensures that if a customer’s details are updated or deleted, the changes will cascade to the interactions table.
5. Save the Relationship:
   • Click OK and save the relationships.

Step 5: Creating a Data Entry Form for Customers

Now that the database structure is ready, we’ll create a data entry form for adding new customers. This form will provide a user-friendly way to input customer data.

Step-by-Step: Creating a Customer Entry Form

1. Use the Form Wizard:
   • In the Forms section of the Database Pane, click Use Wizard to Create Form.
2. Select the Customers Table:
   • In the Form Wizard, select the Customers table as the source.
3. Choose Fields for the Form:
   • Select all the fields (CustomerID, FirstName, LastName, Email, PhoneNumber) and move them to the right column.
4. Select a Layout:
   • Choose a layout, such as Columnar – Labels on Top, for easy data entry.
5. Finish and Save:
   • Save the form with a name like CustomerEntryForm and click Finish.

Step 6: Creating a Subform to Log Interactions

To log customer interactions, we’ll create a subform that links to the Customers form. This subform will allow you to enter interactions directly for each customer.

Step-by-Step: Creating an Interactions Subform

1. Open the Customer Entry Form in Design View:
   • In the Forms section, right-click CustomerEntryForm and choose Edit.
2. Add a Subform:
   • In the Form Navigator panel, right-click the MainForm and choose New > Form to create a subform.
   • Name the subform InteractionsSubform.
3. Link the Subform to the Interactions Table:
   • In the subform properties, set the Data Source to the Interactions table.
   • Under Link Master Fields, set CustomerID in both Link Master Fields and Link Slave Fields.
4. Add Interaction Fields:
   • Add fields from the Interactions table to the subform layout, such as InteractionDate and InteractionDetails.
5. Save the Form:
   • Save the changes to the form.

Step 7: Creating Queries to Retrieve Customer Data

Queries allow you to search for specific customer records or filter interactions based on certain criteria. We’ll create queries to find customer interactions by date and to list customers who haven’t been contacted in a specified period.

Step-by-Step: Creating a Query to Find Recent Interactions

1. Use the Query Wizard:
   • Go to Queries in the Database Pane and select Use Wizard to Create Query.
2. Choose Fields:
   • Select fields from both the Customers and Interactions tables (e.g., FirstName, LastName, InteractionDate, InteractionDetails).
3. Add Date Criteria:
   • Add criteria to filter interactions by date. For example, to find all interactions in the last 30 days, use the Criteria row to add:
     >= DATEADD('dd', -30, CURRENT_DATE)
4. Save the Query:
   • Name the query RecentInteractions and click Finish.

Step 8: Generating Customer Interaction Reports

Reports provide a visual summary of your data and can be printed or exported for analysis. You’ll create a report that lists customer interactions over a specified period.

Step-by-Step: Creating a Customer Interaction Report

1. Use the Report Wizard:
   • Go to the Reports section and click Use Wizard to Create Report.
2. Select the Recent Interactions Query:
   • Choose the RecentInteractions query as the source for your report.
3. Choose Fields for the Report:
   • Select fields like FirstName, LastName, InteractionDate and InteractionDetails.
4. Group and Sort Data:
   • Group the data by CustomerID to show all interactions for each customer.
   • Sort the data by InteractionDate in descending order.
5. Save the Report:
   • Name the report CustomerInteractionReport and click Finish.

Final Thoughts

Congratulations! You’ve now created a fully functional Customer Relationship Management (CRM) system using LibreOffice Base. This system allows you to store customer data, log interactions, generate queries for specific information and create detailed reports. You can expand this CRM by adding more tables, forms and reports as your needs evolve.

This project serves as a foundation for managing customer relationships efficiently and can be tailored to fit any business’s specific needs.
