especially since it can also allow values to be scanned into the chip so that you can start it from a known state. This is particularly useful if a problem occurs only after the chip has been operating for a long time. A state can be quickly scanned into the chip which corresponds to

5. Add the code listed in Listing 7.4 to the SelectedIndexChanged event of the list box called lstSQLServers. This routine starts by testing to see whether a SQL Server and database have been selected. If so, the routine enables the btnConnect button; otherwise, the b[r]
Scalability and Portability MySQL can handle extremely large and complex databases without too much of a drop in performance. Tables of several gigabytes containing hundreds of thousands of records are not uncommon, and the MySQL web site itself claims to use
A relational system does not automatically determine the set of access paths. The access paths must be created by authorized users such as database admin- istrators (DBAs). Access-path selection is not trivial, since an index designer must balance the ad[r]
delimiter, such as a comma or a tab character. For example, in a list of personal contacts, each data record contains an individual contact’s information: the contact’s name, address, and phone number are each a data field. Flat file databases are ideal for storing simple data val[r]
Agility: Provisioning-on-demand enables faster set-up and tear-down of resources on an as- needed basis. When a project is funded, you initiate service, then if the project is killed, you simply terminate the cloud contract. Dynamic scalability: Most applications experience spikes in[r]
The database recovery model controls transaction log behavior in SQL Server databases. There are three database recovery models available: • Simple recovery. This model reuses log file space. This occurs after transactions have been committed to the database[r]
