Information About Data Cleaning And Data Services

Data Cleaning in Huntsville Alabama from NW Database 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.

Northwest Database Services has 34+ years experience with all types of data services, including mail presorts, NCOA, and data deduplication.

Huntsville was established in the Mississippi Territory in 1805, and it became an incorporated city in 1811. Huntsville was the first capital of Alabama when it became a state in 1819. It was built on hills near the Tennessee River and added textile mills in late nineteenth-century.


Huntsville is classified as a humid subtropical area (Koppen climate category Cfa). It has hot, humid summers with mild winters. Average high temperatures range from nearly 90 degrees F (32.2 degC in summer) to 49 degrees F (9.4 degC winter).

On average, August through October are slightly dryer months (see the climate chart for less than 3.6in of precipitation). Droughts are possible, mostly in August and October.
