The Houston Independent School District went live in September with Microsoft
Corp. SQL Server 6.5, which was the latest version of the database available
at the time. As the database grew over the first two to three months, and
more and more people were accessing the system, HISD experienced poor response
time and system locks, said Daryl Ann Borel, HISD assistant superintendent
for technology and information systems.
In January 1999, officials decided to upgrade to the newly available
SQL Server 7.0.
"The upgrade was completed in early March and was extremely successful,''
Borel said. "Response time improved 300 percent, the average wait time was
reduced 876 percent, and the system locks declined to zero." SQL Server
7.0 provides SAP's ERP package with a solid database foundation by increasing
system availability and response time and economizing database size, Borel
said. SQL Server's efficient architecture shrank the previously 45G database
to 30G, saving disk space and increasing performance.
"SQL Server's robust processing capabilities cut data processing time
considerably, and system administration is now simpler than ever," she said.
"Batch and background processing, which previously took three to four hours,
now takes less than 30 minutes to complete. The time needed to generate
reports was cut from a maximum of one hour to less than 15 minutes."
