Steve Hoberman discusses writing effective entity definitions in data modeling. He notes that definitions need to be clear, complete, and correct. The document provides examples of entity definitions for concepts like "Customer" and "Product". It also includes questions from readers about modeling concepts and terms that could be included on a "Bingo card". Hoberman advises being precise in definitions and checking with the business to validate the accuracy of definitions.

What is a customer?
A Customer is a person or organization who obtains our product for resale. The Customer
normally obtains the product through purchase. An example of a customer who does not purchase
our product is the Salvation Army, which receives the product for free as a charity organization. A
person or organization must have obtained at least one product from us to be considered a
Customer. That is, Prospects are not Customers. Also, once a Customer, always a Customer so
even Customers that have not obtained anything in 50 years are still considered Customers. The
Customer is different than the Consumer, who obtains the product for consumption as opposed to
resale.

Assignment 2: Scenario Analysis: Communication and Values In this assignment, you will analyze a communication exchange between a manager and an employee, similar to what occurs in many organizations. When reading the case, consider the terms and concepts from the module readings and how these apply to the scenario. Your response will include these terms and concepts applied in such a manner as to demonstrate both your understanding and application in a workplace setting. Read the scenario and answer the questions. Scenario One Colleen, an account manager for a Big Four accounting firm, loved her job. However, the frequent travel was beginning to wear her down. She had a five- year-old daughter, Lillith, and a husband who often traveled for work as well. The task of balancing their schedules and child care for her daughter was overwhelming for her at times. However, this week, she thought she had everything under control. She had just returned from an important trip and was planning to take a few days off. She had promised Lillith that they would spend time together and that she would attend her preschool “graduation.” They were both looking forward to it. As Colleen prepared to leave for her vacation, her boss, Ricardo, stopped by her office to tell her that she would have to cancel her vacation to cover for a sick colleague. She would need to leave the next afternoon for a trip out of state. Colleen considered Ricardo a friend as well as her manager, so she was sure he would understand when she explained why she could not leave the next day. Surely he would understand that she had an important event planned with Lillith—but he didn’t! Ricardo explained that he needed her. Her colleagues routinely covered for each other, including her, when it was needed. Besides, no one else was available this time. It was in times like these that people showed their commitment to the company. Colleen tried to persuade him to see her point of view. However, Ricardo simply reminded her that the partners were meeting in a few weeks to allocate bonuses and decide upon promotions. Colleen assured him that she was a committed employee but was also a committed parent. Couldn’t she be both? Why did she have to choose between the two? Ricardo said he really did understand but sometimes people have to make hard choices. He said he was sure Colleen would make the right one. The only problem for Colleen was that she didn’t know what the right choice was. Tasks: In 300–500 words, post to the Discussion Area your responses to the following: •Who was more effective—Colleen or Ricardo? •On the basis of the communication terms, concepts, and theories covered in this module, what did the more effective communicator do that made him or her effective? •What values directed Ricardo’s response in this situation? •What values directed Colleen’s response in this situation? •What particular aspects of their communication could have been improved upon and how? Support your ra.

In the B2B world where long buying cycles mean that the role of content is stretched over a wide length of time, it’s absolutely essential for marketers to employ the full spectrum of content, each with its own specific purpose, or desired effect on your buyer.

Manufacturing Project Green Light: How to Gain Corporate Buy-in

Marilyn (Rupp) Cox, PMP

To achieve buy-in, budget approval, or a project green light you must first engage. As marketers we study the art of engagement. We develop programs, content, and analytics to maximize engagement with our prospects, customers, and channel partners. We recognize that we must deliver content that educates, nurtures, and motivates. As marketers we recognize that we must deliver the right content, to the right people, at the right time, and through the right channel. And as marketers we understand that the most effective form of engagement results from storytelling. So why do we fail so miserably at engaging our internal audience? More than any business unit, marketing should have perfected the business presentation. And yet, we often fall back into the bad habit of bullet-point heavy PowerPoint presentations, charts and graphs, and messaging that focuses on what’s missing versus what is possible. In order to succeed you must create an internal environment for success. To do this you must guide the company to the realization that the initiative is a change for the better and that they are a part of that positive change. And much like engaging with your external audience, engaging with your internal audience requires preparation, analysis, relevant content with context, and storytelling.

Problems and solutions for migrating databases to the cloud

IDERA Software

Public cloud uses and limitations

IDERA Software

The cloud is an attractive option for applications like database instances, but there are also many reasons to keep systems on-premises for the time being. Furthermore, migrating to the cloud isn’t always a straightforward process, so it can be time-consuming. As a result, many organizations end up with a hybrid environment in which some systems are in the cloud, while others remain on-premises. The biggest problem with this architecture is managing it, as many tools can only focus on the cloud or on-premises infrastructure. Tools that work in the hybrid cloud can thus save users time and money.

Database administrators (dbas) face increasing pressure to monitor databases

IDERA Software

Database platforms are mature products with powerful capabilities, but they still require regular care to maintain a high level of performance. It’s therefore critical to continually monitor database instances for availability, health, performance and security. This practice generally makes heavy use of automation to handle routine tasks, allowing database administrators (DBAs) to focus on issues requiring human intervention. Database professionals are steadily increasing their use of tools to monitor databases, according to recent surveys.

Six tips for cutting sql server licensing costs

IDERA Software

SQL Server resellers often send true-up forms to their customers more frequently than Microsoft requires, with some customers receiving them every month. They may feel compelled to fill them out each time, but Microsoft only requires one true-up each year. This true-up must also include an update statement that describes the count changes for the previous year. Increasing true-up counts in the EA is quite easy, but reducing the count, also known as truing down, can be very difficult. However, it can be done by performing the following steps.

Idera live 2021: Database Auditing - on-Premises and in the Cloud by Craig M...

IDERA Software

Hackers, thieves, and many cybercriminals are constantly on the lookout for ways to harvest your data and use it for their own nefarious purposes. And where do they look? Everywhere! However, your database systems are the most likely target because that is where the data is located! And increasingly, your data is not just on computers running in your data center, but also in the cloud. So, organizations must be ever-vigilant to see who is accessing the sensitive corporate data in your databases usage and protect it from unauthorized access. Protecting your data for business reasons is a big enough reason to check your data access. In addition, many governmental and industry regulations exist that mandate you do so. Each regulation places different demands on what types of data access we must watch and audit. Ensuring compliance can be difficult, especially when you need to follow multiple regulations. And you need to capture all relevant data access attempts while still maintaining the service levels for the performance and availability of your applications. This webinar discusses these issues as well as presenting the requirements for auditing data access in relational databases. The goal of this presentation is to review the regulations affecting the need to audit at a high level. Then, the speaker will discuss the things that need to be audited, along with pros and cons of the various ways of accomplishing this. The presenter, Craig Mullins, is president and principal consultant of Mullins Consulting, Inc. where he focuses on data management strategy and consulting. Craig writes the monthly DBA Corner column for Database Trends & Applications magazine. With over three decades of experience in all facets of database systems development, he has worked as a programmer and analyst, a database administrator, an industry analyst, a software executive, and a consultant.

Geek Sync | How to Be the DBA When You Don't Have a DBA - Eric Cobb | IDERA

IDERA Software

Not everyone has a full time database administrator on staff, and in many cases the responsibility of managing the SQL Server falls on the developers. But as long as the backups are running successfully you’re good, right? Not exactly. Your databases could be heading for trouble! Without proper tuning and maintenance, your database performance can grind to a halt. Tailored to the “Non-DBA”, this session will show you how to configure your SQL Server like a DBA would, and why some SQL Servers default settings may be slowing you down. Discussing server settings, database configurations, and recommended maintenance, you will leave this session with the knowledge and scripts you need to help configure your SQL Server instance to fit your workload, and ensure that your SQL Server and databases are running smoothly.
