    Engaging a team of software developers requires expertise, patience, and communication between the development team and team that owns and understands needs of the business. There are times that business can operate well with commercial software applications. Some businesses buy multiple tools. At some moment, the leaders within a company acknowledge that their internal or external business workflows are inefficient, or inaccurate, or incompatible with their other technology.

    Is there something about your business that sets you apart from the other businesses? What is your competitive advantage? What are the messages you are sending to your clients? Invoicing represents a classic example of this topic.

    What is an invoice? First definition: It is a document that communicates what a client owes a vendor.

    During this episode we will explore how an Oracle database can produce a document and we will explore some of the ways that organizations use and design invoices.

    Construction contractors and many other trades love to see scope changes and project expansion. Project expansion and scope changes increase revenue and often increase the size of a team. Sometimes the need for more done at a faster rate comes introduces risk to a project. Using modern software development techniques whereby the team work in 2-4 week sprints, we often see issues long before we must deal with them. How does one solve problems that remain at the horizon? I argue that a mature team works towards the unknown together acknowledging the squishy-bits. We should stand together, client and developer, embracing the challenges – studying them.

    When we start a new software project we “swing with a big hammer”, standing up structures and framework quickly. What we build resembled the both the native Oracle APEX environment plus the client’s colors, logos, and fonts. Through this initial framework, we, the development team, offered a vision. From here a shared vision developed through shared work. We also needed to accommodate the multiple languages of French, Dutch, and the English that the developers depended on. We need to comply with European data privacy laws which are stricter than those in the United States. Building a robust application that accommodates the nuanced complexities that our client will require to differentiate and support their business practices, we design speed and resilience into our system. Designing for speed, also means avoiding techniques that rob us of speed.Speed within a database environment involves honor a series of rules called “Data Normalization”. A discussion about data normalization typically involves slides discussing abstract rules about optimizing complex data within a database environment. Edgar “Ted” Codd, born in 1923, invented the relational model for database management. He worked for IBM. He received the Turing Award in 1981. Dr. Cobb developed the relational model for databases in 1969. Sixty years later, his initial work expanded. The initial data normalization steps I learned have expanded and some nomenclature changed.The amazing thing to me is that people being invented relational databases. And people invented programming languages. Today, we argue about these topics forgetting the humanity underpinning these technologies. My favorite college professor, John Jungck, stood before his Bio 101 course each year to give a lecture called: “There are No Facts”. Unlike modern disputes about facts, he forced no political agenda. He challenged each in the audience to approach science and technology with an open mind. We must eschew assumptions. “Oh, you think two plus two equals four?” Then he reaches under the lectern. He pours two liters of clear water-like fluid into a container with two liters of clear water-like fluid. The total was a bit less than the expected four liters. A bit of chemistry happened given that one of the fluids was not water. Bluntly put, he performed a parlor trick for us. As an illustration, it works. He encouraged student to be curious, skeptical, and carry a bit of doubt when people get dogmatic about anything.All of this technology we use to build and support software applications results from inventions and ideas that came the mind of people. People like you and like me. We invented it all. When honoring the process of normalizing data, we gain speed and maximize performance within relational databases. I do promise, we are talking about how to manage multiple spoken languages within a database. In Episode 2 “Data Tables”, I mentioned that my colleague Dirk provided us with 132 data table definitions filling over 5000 lines of text. I discussed the importance of a unique primary key for each row, or record, of data. One row of data contained the data profile for precisely one subject. One example was the customer table. The customer table has a primary key called the customer_pk. All of the data within that row must related to that exact customer. If it doesn’t related to or describe an element of the client’s profile, then it does not belong. That statement of “fact”, which I surrounded with quotes, complies with the First Normal Form of data. Thank you Doctor Cobb. You documented this idea and stamped it with a name in 1970.When a data row has a singular primary key, as our customer table does with the customer_pk, then it meets the standards for the Second Normal Form. Well done us. This seems obvious to software developers. It seems so obvious to some that we forget the intelligence and humanity behind this concept. Database tables relate to each other. We do not store each and every invoice within the customer table. Instead, we create a table that stores the invoice data. In that table, we’ll have a unique primary key called invoice_pk (meeting both the first and second normal forms – well done us). In the second position of that invoice table, we keep the foreign key for the customer table. That foreign key, our team calls customer_fk. I look at that knowing instantly that invoices relate to customers and the customer foreign key connects to the customer primary key. We break the data into logical and non-duplicating elements. For example, some may opt to put a customer’s address in the customer table. Here’s the street name, the municipality name, the state or province, and the postal code. Suddenly, we find a customer with two addresses. Or maybe one address is for mailing and the other is for shipping. Maybe one address is the physical address, etc. We have all experienced this complexity. When I order from an ...
