Does My Company Need Managed Hosting?
Managed hosting offers many benefits to a business wishing to expand their operations or make themselves accessible to their customers online. By having an online presence, a business can increase their exposure to a local, national, or worldwide audience.
Nevertheless, a business that has a website is a business that can accomplish a lot more because they are allowing customers to learn more about them and gain wider access to what it is they have to offer.
There are several definitions that describe what managed hosting is. The service that is provided really depends on the needs of the business and how they handle their managed hosting. These definitions are:
A single website hosted on a web server that is supported by a managed hosting provider.
A service in which the dedicated server is managed for the business by a managed service provider.
Managed hosting manages and maintains the dedicated server.
Managed hosting is performed by a web host in addition to providing many services for the dedicated servers that they provide.
The business doesn’t have their own dedicated server, but they are using the servers that belong to the host, which means the host is maintaining shared-servers. However, the business still maintains the privacy of its website although the servers are shared and receives all of the benefits they would have and possibly more than if they had their own dedicated server.
It is easy to see that there are many different forms of managed hosting. Depending on the needs of the business the MSP provides services to, different services can be provided. Not every business has the money to hire IT professionals and train them or train existing employees to take care of their web hosting. That is why it is feasible to outsource the jobs to managed hosting. It is actually cheaper to outsource because there is a fixed monthly rate in which the company pays that usually does not add up to the monthly salary of a single employee.
What this does is maximize profit and allows the business to focus on their customers satisfaction rather than having to spend time managing the website. If a business only had time to manage their website, they would not have time to serve their customers. In the end, there would be little impact on person-to-person sales. The idea is for the website to enhance both person-to-person sales and Internet sales, if applicable.
Other benefits
There are many more benefits of managed hosting such as security and up-time. It is very important that the website stay secure so that people with malicious intentions are unable to disrupt business on your website. Malicious activity can result in many hours of trying to bring the website back up and this also results in down-time. There is nothing more aggravating than going to a website with poor up-time either because of security breaches or issues with the server.
Managed hosting performs continuous security scans and also continually checks for issues that may interfere with the sites up-time. That is why many websites that are managed by managed hosting have 100% up-time.
So if you are not sure whether or not you need managed hosting, ask yourself these 5 questions:
How would my business benefit from a website?
Does my business have the money to operate and maintain a website?
Do I have the manpower to continually monitor a website?
Do I have the money to hire and train additional employees?
How much would managed hosting cost me compared to doing it on our own?
Asking yourself these questions will put you on the road to finding the best solution for your business.

Taking A Look At Database Applications
If you are not familiar with how databases work, then it can seem a little overwhelming in the beginning. It can all be simplified with a little information. A database is collected data arranged in a specific way, making it simpler and easier to find data when needed. While a data base can be used for single user applications, they are very helpful for systems that have multi-users.
The most popular type of database is the relational. This type of database makes it easier to find and sort specific information. Tables are used to store information. Each table contains a column or multiple columns to store information that can be found easily when needed. The original databases were flat and information was filed in one long text file.
Each entry contained several pieces of information about a subject. However, the text files in a flat database made it harder to find specific information quickly. There is also something called a hierarchical database.
Data is organized in a tree like structure using an upward link in each record. The network models store records with links to other records. Here are some tips that can help you to recover data with your database.
There are several methods you can choose from for backup and recovery of databases. Some deal with full backup and some deal with selective backup. Make a checklist of files on your computer.
This will help you decide what to backup and what isn’t really necessary or important, in case of lost data. Full backups are exactly as they sound; a full copy of the database is stored on the backup media. Full backups can be done without taking the database offline.
Full backups can take longer to complete than some of the others. Next we have what is called the differential backup. The differential backup only stores a copy of the data that has changed since the last full backup was completed.
It is very important to remember that if you do have a database failure, since a differential backup would not be helpful with recovering lost data. You would need both the full and differential backups to restore your database properly.
If you regularly make backup copies of your files and store them in a separate, safe place, then you can get most if not all of your information back if something happens to your originals. Transaction logs track all modifications that are done within your database, even unfinished transactions.
Binary logs contain all events in the database that did or could contain modified data. Binary logs are used to support server replication and can be used as backup.
The method of backup that works best for you will depend on databases storage engines. There are several backup services methods available and a little info will help you choose the right one for you. You may choose to use a CD-RW or a DVD-RW.
These mediums are used to backup data onto either a compact disk or a DVD. Another option to recover data is the USB flash drive.
The flash drive is a mini hard drive that will plug straight into any usb port on your computer, allowing you to download your files directly to it, or vise versa. You may also wish to store your files using an online storage system.

Learn about Subqueries in Access Courses
An understanding of queries is critical to database management. Without queries, you can’t get at the information and the data is useless.
Once you master queries, a subquery is a powerful tool that greatly expands your abilities to get exactly the data you need. To unleash the real power of a subquery, you need to become familiar with SQL (pronounced “sequel”), the language of database queries. This type of knowledge, usually taught in advanced level Access courses and can make your database exponentially more powerful.
Subquery Basics
As you would learn in Access courses, a query in SQL is a SELECT statement. A subquery is simply a SELECT statement within a SELECT statement.
For example a simple query from our Access courses might read like this:
SELECT Employees.Name, Employees.Salary
FROM Employees;
This retrieves a list of employee names and their salaries from the Employees table.
A subquery from advanced Access courses could appear as such:
SELECT Employees.Name, Employees.Salary
FROM Employees
WHERE Employees.Salary IN
( SELECT TOP 5 Salary
FROM Employees AS Dupe
WHERE Dupe.Salary = Employees.Salary);
The main query pulls the same list of employees and their salaries. The subquery then takes from that list the five highest paid employees and puts them in a separate table aliased as Dupe.
Subqueries make it easy to perform such tasks as:
- Expressing values such as sales made in a given month as a percentage for all sales in the year
- List customers who haven’t ordered in 60 days or employees who haven’t made a recent sale
- Extract demographic data on customers from a specific state or city
- Calculate year to date totals
Problems With Subqueries
After learning how to create subqueries you will also learn some of the pitfalls to avoid.
Complex subqueries can perform quite slowly. If you find that performance is poor, try a stacked query instead. Make your first query then use the output table as the input table into the second query. Avoid nested subqueries (a query within a query within a query) as they can really drag down performance.
Subqueries that use the same table as the main query will require aliases, as demonstrated in the example above. The subquery uses the alias Dupe to make it clear it is referring to fields in the output of the main query and not in the main Employees table.
Sometimes Access just chokes on what seems to be a straightforward subquery. Verify the statement, confirming things like matching data types and that none of your names are on the reserved words list. Rewrite the query or, if necessary, break it into stacked queries.
Subqueries are incredibly powerful and flexible tools for data access but can also be a source of frustration and error if used incorrectly. Though they can be complicated, you may be amazed at how much more control you have over your data once you master this knowledge.
