Choosing names is an aspect of database design that is often neglected but can have a considerable impact on usability and future development. To avoid this, both table and column names should be chosen to be meaningful and to conform to the established conventions, ensuring that consistency is maintained throughout a system. A number of conventions can be used in relational database names, including the following two examples for a record storing a client name: 'client_name' and 'clientName.'
Lack of Documentation
Creating documentation for a relational database can be a vital step in safeguarding future development. There are different levels of documentation that can be created for databases, and some database management systems are able to generate the documentation automatically. For projects where formal documentation is not considered necessary, simply including comments within the SQL code can be helpful.
Failure to Normalize
Normalization is a technique for analyzing, and improving on, an initial database design. A variety of techniques are involved, including identifying features of a database design that may compromise data integrity, for example items of data that are stored in more than one place. Normalization identifies anomalies in a database design, and can preempt design features that will cause problems when data is queried, inserted or updated.
Lack of Testing
Failure to test a database design with a sample of real, or realistic, data can cause serious problems in a database system. Generally, relational database design is started from an abstract level, using modeling techniques to arrive at a design. The drawback to this process is that the design sometimes will not relate accurately to the actual data, which is why testing is so important.
Failure to Exploit SQL Facilities
SQL has many capabilities that can improve the usability and success of a database system. Facilities such as stored procedures and integrity checks are often not used in cases where they could greatly enhance the stability of a system. Developers often choose not to carry out these processes during the design stages of a project as they are not a necessity, but they can help to avoid problems at a later stage.

How to Plan a Bike Ride FundraiserIn Feburary 2016 06,
In Feburary 2016 06,
Select a date for the event based on other athletic events in the area or fundraisers that may take away from your core audience. Choose a rain date if the target audience is diverse in cycling experience or geared toward families and children. However, if the charity ride will be geared toward experienced riders or mountain bikers, weather should not deter them from riding.
Form a steering committee that includes at least an event coordinator and volunteer coordinator who have experience organizing a cycling event and/or participating as a rider in similar events. They will help you avoid overlooking details that are important to cyclists and bike rides.
Establish a budget, expenses and target fundraising goal.
Select a location and a back-up location (ideally four to six months in advance.) You'll need enough time to get permissions, submit necessary permits and coordinate municipalities to lock down the details of the event. Keep the back-up location in mind, and be ready to move fast if your first choice is denied.
Choose the bike route. For a mountain bike event, match trail difficulty with the experience levels of the riders. You may want to select one route and have more advanced riders complete multiple routes. Mark trails clearly with arrows and warning markers that cannot be confused with existing trail markers.For a road bike ride, come up with a set of distance options for riders. Typically, a set of 10-, 25-, 50-mile routes will satisfy most charity cyclists. If you feel adventurous, include a 75- or 100-mile route. Use the longest route as the 'base' for all other distances; for the shorter distances, figure out turnaround points. Develop a turn-by-turn cue-sheet.
Establish rest areas every 10 miles for a road bike event and every 3 miles for a mountain bike event. For each rest area, arrange for a set of volunteers (preferably one that has some form of medical experience), water, food, first aid, a safe place for riders to set their bikes and a means for riders to go to the bathroom.
Location, Sponsors, Registration
Contact municipalities, parks and recreation committees, and police departments in the area of the bike ride. If you are hosting a mountain bike ride, you will likely have to file a permit application to use the property and arrange for insurance. For a road ride, some townships require police presence and permission to post signs promoting the event and marking the courses.
Approach local bicycle shops, outdoor and sports centers, and gyms owners for mechanical assistance, to hand out invitations to their customers and to provide volunteers or run a rest area in exchange for marketing. If you plan to provide swag bags to participants, ask bike shop owners to donate items for the bags.
Contact local supermarkets and food stores to donate food and water for before, during and after the ride in exchange for advertising. Ask local businesses to sponsor a rest area by providing food, water, mechanical support and/or port-a-potties and inviting employees who aren't working during the hours of your event to run the rest area. Invite business owners to form teams to ride in your event.
Post your event on Active.com or BikeReg.com to accept participant registrations. Active.com has greater visibility and may attract noncyclists to the event. BikeReg.com will target specifically cyclists.
Arrange EMT support, support wagons, course markers, bibs (RoadID sponsors rides and can provide bibs as part of their support) and a volunteer schedule. Contact local fire departments, Lions clubs and volunteer ambulance corps to provide medical support.
Obtain 'Special Event' insurance as needed. Most parks and recreation departments will let you know what their insurance requirements are. Bear in mind costs and requirements will vary greatly depending on the state your event is in, whether or not your ride takes place on state or local property and the number of anticipated riders.
