BA Community: http://www.ModernAnalyst.com Many analysts think that “data modeling” means designing databases and technical data models. Business users have no capability of creating and consuming that level of technical design, but they very much do care about their business data requirements. They can describe how the data is used to make business decisions and how they want to see it processed by the system. This webinar will introduce a set of requirements models for data that help describe the relationship of data in the system, details about fields, how data is used to make decisions, and how data is processed by the system. We’ll describe how the models can be used together from top to bottom to create a complete picture of the data needs and how they integrate to other requirements models to fully round out the requirements.

Adam Fuchs, CTO and Co-Founder of sqrrl, discusses how to bring structure to noSQL database environments in this whiteboard session hosted by Wikibon's Dave Vellante. NoSQL continues to gain adoption, primarily due to the need for it in corporate daily operations and the freedom it provides compared to the rigid schemas associated with relational technologies. That's the big picture from Coucbbase, which today announced the results of a survey it did with 1,300 practitioners. Couchbase is one of the leading vendors in the NoSQL market so it's not a big surprise to see them publish these rosy results. But the finding do speak to the overall transformation of the database market and the roaring plume of data that is shaping a new tech landscape. I agree that NoSQL has moved beyond the experimentation phase. In part, you can thank Oracle for that. The fact they jumped into the market has given customers more reason to invest more capital into the technology. It's a validation point. Here are some of the results from the survey: Nearly half of the more than 1,300 respondents indicated they have funded NoSQL projects in the first half of this year. In companies with more than 250 developers, nearly 70% will fund NoSQL projects over the course of 2012. 49% cited rigid schemas as the primary driver for their migration from relational to NoSQL database technology. Lack of scalability and high latency/low performance also ranked highly among the reasons given for migrating to NoSQL (see chart below for more details). 40% overall say that NoSQL is very important or critical to their daily operations, with another 37% indicating it is becoming more important. Couchbase asked how companies are using NoSQL Some interesting answers included that go beyond the traditional use cases: real-time tracking and segmentation of users for ad targeting disaster recovery inventory tracking manufacturing automation insurance underwriting multi-call center operations (with replication of production data) Twitter stream analysis Respondents were also asked about what they expect and hope for out of NoSQL in 2012. Couchbase breaks down what they say into four boxes: schemas; replacing RDMS/making it default database; scalability/performance and speed/agility in app development. Answers included: Gaining freedoms from inflexible schemas that do not adapt well to changing business requirements. Making NoSQL an integral part of daily operations and handle at least 30% of transaction load. Allowing the capability to share billions of documents across multiple commodity servers. Help in deploying new features faster without having to manage SQL patch scripts and migrations. ServicesAngle NoSQL -- it fits with so much that we write about. It's a huge factor in the transformation of the enterprise and a necessary focus for any services provider looking to provide a level of value added services.

Here are 5 Tips for System Design interviews. They are helpful when preparing for a System Design interview. 1) Don't get into details prematurely 2) Avoid fitting requirements to a set architecture in mind 3) Keep it simple, stupid! Remember to look at the big picture and avoid too many hacks when solving. 4) Have justifications for the points you make. Don't use buzz words or half hearted thoughts in your design. 5) Be aware of the current solutions and tech practices. A lot of solutions can be purchased off the shelf which simplify implementation. You should be able to argue for a custom implementation with it's pros and cons. Have these on the back of your mind during you interview, and all the best! Here are three major points evaluated during the interview: (1) Clarity of Thought a) Express your thoughts in a clear manner. b) Justify your decisions. Critical reasoning and argument are key to a successful software design. c) When faced with a problem, use standard approaches to mitigate it. For example, say you are faced with an availability problem. State that replication and partitioning help increase availability in general, and move on to offer a solution. d) Don’t make points without thinking them through. Half-hearted attempts at solving problems are frowned upon heavily. (2) Knowledge a) Stay up to date with the current solutions in the market. This includes products and design practices. If NoSQL is being adopted left right and center, you need to be aware of it. b) Know when to pick a solution vs. building something custom. If you name a product, you should be (generally) aware of the features it provides. c) Design practices enable you to meet custom requirements. Examples are decoupling systems, load balancing, sticky sessions, etc… (3) Flexibility a) Switch your targets as the requirements shift. If the interviewer wants to know about one particular part of the system, do it first. b) Never have a set architecture in mind. We all try to fit requirements to a system, but only after it has been shaped by the initial ones. A rigid attitude creates a brittle architecture. It will break before you do. c) Take a step back at times to make adjustments to the general architecture. Being focused on one part can narrow our vision and bloat those areas. There will be components which can be extracted out and extended to the rest of the system. Cheers!

As a business analyst, and as a developer, your world will revolve around a Source To Target Mapping. This is usually an excel sheet, also called a Crosswalk or Interface Design Document. These are a layout that analyzes the source, or legacy, systems and also describes the business rules and transformations that need to take place in the client's to be database design. This is at a very granular, database level and is completeness during the requirements gathering process is crucial. The design specifications that are described here encapsulate all the requirements of the project in one way or another, which will be seen in the data dictionary, and definitely in the transformation rules and conditions upon which certain data is loaded.

Learn how to create an Entity Relationship Diagram in this tutorial. We provide a basic overview of ERDs and then gives step-by-step training on how to make an ER diagram with correct cardinality. Entity Relationship Diagrams are comprised of 3 main categories: entities, attributes, and relationships. Entities are objects or concepts that are associated with important data—like a customer, order, or product. Attributes represent properties or traits of an entity, such as a customer’s phone number or home address. Relationships demonstrate the link between entities. Another main aspect of of ERD's is cardinality, which further defines the relationship between entities in a numerical way. Certain symbols signify the minimum and maximum relationship between different entities.

Learn how to make Use Case Diagrams in this tutorial. Both beginners and intermediate UML diagrammers will find all the necessary training and examples on systems, actors, use cases, and include and extend relationships. UML Use Case Diagrams show a system or application; then they show the people, organizations, or other systems that interact with it; and finally, they show a basic flow of what the system or application does. This tutorial explains the four main characteristics of Use Case Diagrams: systems, actors, use cases, and relationships. A system is whatever you’re developing. It could be a website, a software component, a business process, an app, or any number of other things. You represent a system with a rectangle. The next aspect of Use Case Diagrams are actors. An actor is going to be someone or something that uses our system to achieve a goal, and they're represented by a stick figure. Use Cases are elements that really start to describe what the system does. They're depicted with an oval shape and they represent an action that accomplishes some sort of task within the system. The final element in Use Case Diagrams are relationships, which show how actors and use cases interact with each other. There are different types of relationships (like association, include, extend, and generalization) that are represented by varying types of lines and arrows. —— Learn more and sign up: http://www.lucidchart.com Follow us: Facebook: https://www.facebook.com/lucidchart Twitter: https://twitter.com/lucidchart Instagram: https://www.instagram.com/lucidchart LinkedIn: https://www.linkedin.com/company/lucidsoftware

What is BUSINESS RULE? What does BUSINESS RULE mean? BUSINESS RULE meaning - BUSINESS RULE definition - BUSINESS RULE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. A business rule is a rule that defines or constrains some aspect of business and always resolves to either true or false. Business rules are intended to assert business structure or to control or influence the behavior of the business. Business rules describe the operations, definitions and constraints that apply to an organization. Business rules can apply to people, processes, corporate behavior and computing systems in an organization, and are put in place to help the organization achieve its goals. For example, a business rule might state that no credit check is to be performed on return customers. Other examples of business rules include requiring a rental agent to disallow a rental tenant if their credit rating is too low, or requiring company agents to use a list of preferred suppliers and supply schedules. While a business rule may be informal or even unwritten, documenting the rules clearly and making sure that they don't conflict is a valuable activity. When carefully managed, rules can be used to help the organization to better achieve goals, remove obstacles to market growth, reduce costly mistakes, improve communication, comply with legal requirements, and increase customer loyalty. Business rules tell an organization what it can do in detail, while strategy tells it how to focus the business at a macro level to optimize results. Put differently, a strategy provides high-level direction about what an organization should do. Business rules provide detailed guidance about how a strategy can be translated to action. Business rules exist for an organization whether or not they are ever written down, talked about or even part of the organization's consciousness. However it is a fairly common practice for organizations to gather business rules. This may happen in one of two ways. Organizations may choose to proactively describe their business practices, producing a database of rules. While this activity may be beneficial, it may be expensive and time-consuming. For example, they might hire a consultant to comb through the organization to document and consolidate the various standards and methods currently in practice. More commonly, business rules are discovered and documented informally during the initial stages of a project. In this case the collecting of the business rules is incidental. In addition, business projects, such as the launching of a new product or the re-engineering of a complex process, might lead to the definition of new business rules. This practice of incidental, or emergent, business rule gathering is vulnerable to the creation of inconsistent or even conflicting business rules within different organizational units, or within the same organizational unit over time. This inconsistency creates problems that can be difficult to find and fix. Allowing business rules to be documented during the course of business projects is less expensive and easier to accomplish than the first approach, but if the rules are not collected in a consistent manner, they are not valuable. In order to teach business people about the best ways to gather and document business rules, experts in business analysis have created the Business Rules Methodology. This methodology defines a process of capturing business rules in natural language, in a verifiable and understandable way. This process is not difficult to learn, can be performed in real-time, and empowers business stakeholders to manage their own business rules in a consistent manner. Gathering business rules is also called rules harvesting or business rule mining. The business analyst or consultant can extract the rules from IT documentation (like use cases, specifications or system code). They may also organize workshops and interviews with subject matter experts (commonly abbreviated as SMEs). Software technologies designed to capture business rules through analysis of legacy source code or of actual user behavior can accelerate the rule gathering processing.

The video was made using Access 2010, however the process is very similar in Access 2007 and Access 2013. We'll be going as far as setting up the database tables, which traditionally would be stored in a so-called 'back end' database file, while forms, queries and report, which are not covered in any details by this tutorial, would be stored in a separate 'front end' database file. The tables from the back end are then 'linked' to the front end, so that it behaved as if all the objects were in one file. In some places we have made the design deliberately simple in order to keep our relationships clean and the number of tables low. This helps those new to Access to get their heads around how to create the database, but for actual use, might cause problems. We recommend that you learn more about database design from other sources before beginning your project if you intend to use it for a real business. Key topics to consider are: database normalisation theory; Inner, Left, Right and Outer Joins; Basic SQL (structured query language) use; Software Development Methodologies; UX (user experience) enhancement techniques; and of course, the very specific needs of your business, project or client. All together, a broad knowledge of these topics will allow you to design your tables with enough foresight to make the setting up of the queries, forms and reports you'll need later as easy as possible. Plus it should make the system easy to use and less likely to be corrupted or crash. Keep in mind that even if your stock database needs don't fit very well with our example parts database, or if you need an entirely different kind of system like an accounts database or CRM database, the lessons in this tutorial can still apply.

An Entity Relationship Diagram (ERD) is a data model describing how entities (or concepts or things) relate to one another. When created by business analysts or business users, ERDs can be used to understand the business domain, clarify business terminology, and connect business concepts to database structures. Watch this tutorial to learn how to create and review an ERD with BUSINESS users. We cover conceptual or logical ERDs, that visually show how the terms in your glossary relate to one another and are a great business communication tool. (This might surprise you as typically ERDs look almost ridiculously complicated. That’s because most ERDs are automated output from physical database designs, not carefully crafted abstractions o f business concepts.) And here’s the link to the Visual Model Sample Pack I mention in the video: https://bridging-the-gap.com/vmsp To learn more, check out the blog post at https://www.bridging-the-gap.com/erd-entity-relationship-diagram/

http://bit.ly/1GlhVYE – In this week's Whiteboard Walkthrough, Ted Dunning, Chief Application Architect at MapR, talks about how current trends are turning the internet upside down. He also talks about how this is leading to the requirements for very very high speed time series databases, which leads to practical designs based on modern NoSQL architectures to implement these high speed time series databases.
