Information About Data Cleaning And Data Services

Determine the Purpose of Your Model

First, decide what your model is for. What problem does the model attempt to solve? What are the requirements? If you plan to use predictive analytics data, your model should reflect this. This means that it should focus on the most relevant elements to the task. A clear focus and set of goals will allow you to identify the relevant entities and their relationships in the model.

Identify the Major Entities (And Their Attributes) in the Model

Next, identify the major entities within your model. Entities are the data ‘things’ that you are most interested in. If you are tracking customer orders, for example, the main entities would be customers and orders. You will also need to identify the attributes and values of each entity. Customer attributes might include first and last names as well as telephone numbers. Order attributes could include the order’s price, the item or its SKU.

Define the Relationships Among Entities

Once you have identified the major entities of the model, it is time to establish the relationships between them. If you track customer orders, for example, each customer’s shipping address might be the relationship between them. These relationships can be defined by creating a rough model of the data. This is the first step in understanding the data’s structure and any potential problems.

Identify Integrity Rules, and Constraints

Integrity rules and limitations keep data consistent and accurate while also ensuring they fulfill the functions of your database. Data must be organized in a logical way that makes it easy to update, delete, retrieve and search. You’ll be familiar with rules and constraints if you have ever used Microsoft Excel. If a column is marked with the “NOT NULL” constraint it means that the column can’t store NULL values. This could mean that an order must have a customer number and a product number in order to be valid.

Identify the Data That Must Be Included in Your Model

Next, identify the data that must be included in your model. To help you identify gaps in your data, you can create a diagram or a sample. You might already have the data, or you may need to funnel it into your model.

Tulsa was settled by the Lochapoka Band, a Native American tribe of Creek Native Americans. The majority of Tulsa remains part of the Muscogee Nation (Creek).


Tulsa is a subtropical climate with a temperature of 61.3 degrees Fahrenheit (16.3 degrees C) and an average annual precipitation of just below 41 inches (11,000 mm). The average monthly precipitation drops from December to February and then rises dramatically in May when it averages 5.9inches (150mm) of rain. Although it is possible to still get wet in June, the dry season runs from June through August. Tulsa sees a secondary rain peak in September and October on average. Weather patterns in temperate zones vary seasonally with extremes in temperature or rainfall.

Although internal transportation is heavily dependent on automobiles it was ranked among the five most expensive metropolitan areas in terms of average gas prices at the pump.

Top Businesses

Tulsa’s economy was traditionally dominated by the energy sector. Six months after the United States entered World War I, the United States Oil and Gas Association (formerly known as the Mid-Continent Oil and Gas Association) was established in Tulsa. Tulsa was known as “The Oil Capital of the World” at the time. The association was formed to supply petroleum to the Allies. The association has been a leader in advocating for domestic oil and gas producers over the years.
