communicate your database s capabilities more effectively with MS Visio

If you own a company, then you no doubt can appreciate that keeping your databases current and fully functional are key to keeping your business up and running at full steam. That record of data or records comes in handy for your sales department, and any number of different divisions that work together to keep your company running at optimal levels. When it comes time to prepare documents, presentations or reports that describe all of the wonderful functions that your databases perform, you will want to incorporate Visio database diagrams to make all of your business documents easier to understand and more visually exciting to read.
When you have several people working together as a team on a project that involves various databases, it makes sense to communicate the information that the databases provide effectively, so that the group can work together efficiently. Visio software can help with this important task. In order to get the most effective support from your visio developer, you will need to be able to help manage the visio database and also have the capability to ask questions and set up scenarios using the data from the database. Visio files can help you picture how all of those different processes function, in an easy-to-understand visual manner. Flow and work charts, graphs and other diagrams can be created on a template page that utilizes Visio shapes to create the images that best describe your database s functions.
If you are responsible for training new employees that will be working with your company s databases, you need a quick and easy way to let them know about each database s function and how they connect and relate to each other. Visio diagrams can make that happen, and easier than you might have thought possible. With pre-installed templates, you can create diagrams on your own. If you require quite detailed pictures to describe your databases functions, customization of Visio can make that possible. Visio developers can consult with you to determine your specific business s needs, and then create the shapes that will make your descriptions of your databases specific, and therefore more useful.
You can also utilize Visio in conjunction with other Office software that you rely upon, such as Excel, and convert the data in your Excel spreadsheet into a visual representation of that information through the connectivity of Visio. These diagrams can also be used in an analytic fashion, to help you notice trends and take timely action based on those trends that can improve the usefulness of your databases. You can also update your diagrams as you have new information to import, and this can help you keep track of your databases quality and integrity, both crucial factors upon which your databases depend.

Cisco CCNP / BSCI Certification: Introduction To ISIS Terminology

When you re studying to pass the BSCI exam and earn your CCNP certification, you re going to be introduced to ISIS. ISIS and OSPF are both link-state protocols, but ISIS works quite differently from OSPF. You must master these details in order to earn your CCNP.
One of the major differences between OSPF and ISIS will be evident to you when you first begin your BSCI exam studies, and that is the terminology. ISIS uses terms that no other protocol you ve studied to date uses, and learning these new terms is the first step to BSCI and CCNP exam success.
First off, what does "IS" stand for in "ISIS"? It stands for "Intermediate System", which sounds like a group of routers. As opposed to Autonomous Systems, which are logical groups of routers, an Intermediate System is simply a single router. That s it.
You ll also become familiar with End Systems, referred to in ISIS as an "ES". The End System is simply an end host.
ISIS and OSPF both use the concept of areas, but ISIS takes a different approach to this concept. ISIS routers use three different types of routing levels, according to the area a router has been placed in. Level 2 routers are connected only to the backbone and serve as a transit device between non-backbone areas. Level 1 routers are totally internal to a non-backbone area.
ISIS uses both Level-1 and Level-2 Hellos, meaning that the two types of routers just mentioned cannot form an adjacency. Luckily for us, there is a middle ground, and that is the Level 1-2 router. These routers connect non-backbone areas to backbone areas. L1-L2 routers keep two separate routing tables, one for L1 routing and another for L2 routing. This is the default setting for a Cisco router, and L1-L2 routers can form adjacencies with both L1 and L2 routers.
Part of the challenge of learning ISIS is getting used to the differences between ISIS and OSPF. Keep studying the terminology, master one concept at a time, and soon you ll be a master of ISIS and a CCNP to boot!

VoIP - Voice Over Internet Protocol

Voice over internet protocol or VoIP is beginning to come into it s own. The promise of cost savings over traditional phone lines is driving this technology into the mainstream. Leveraging your existing broadband connection to save on your monthly phone expense at first glance makes sense. Let s take a closer look.
First off, can your existing broadband throughput handle the additional strain of digital voice transfer? You can use your favorite search engine (google, msn, yahoo, etc.) and search for VoIP broadband test to get a general idea of the speed of your connection. This is only the first consideration.
How is your existing broadband access coming into your home? If you re using DSL then using VoIP for your primary phone line may not be an option. DSL availability without existing phone service is not generally available. You should check with your local phone company before canceling service. You just might end up with no phone service, VoIP or traditional. Check first.
If you re using cable internet access and your connection speed test looks good, find a VoIP provider that allows for a trial period. You may find a good provider that offers up to 30 days for you to cancel if you are not satisfied with voice quality or service.
A VoIP converter and a router will be required to setup your VoIP service. Your modem would plug into your router. Next your converter plugs into your router and your phone base plugs into your converter. Most normal phones should work fine. There isn t any special phone required to use this type of service. The entire process is pretty painless, but if you should run into any issue, your provider should be ready to help.
If you re looking to leverage your existing broadband internet access to save money on your monthly phone expense, VoIP can be a great option. Just remember to check your connection, check with your local phone provider (for DSL users) and find a provider that offers a money back trial period. This can be a great way to save money, but don t be pressured before you know the facts. Even if it doesn t work out for you now, keep your eye on this technology.
The FCC is already involved in the apparent conflict between VoIP service providers and DSL access. E911 service (Enhanced 911 service) is already being mandated and additional steps will be made to bring this technology further into the mainstream. Make no mistake about this technology. It has arrived and is here to stay.
