As with all software installations on Windows operating systems, you must be an administrator on the computer to install SQL Server Express, ArcGIS Desktop, and the tutorial data. If you do not have administrative rights to the computer you are going to use for this tutorial, have your systems administrator install the software. Be sure the system administrator adds your login to the database server as an ArcSDE database server administrator when he or she enables the SQL Server Express instance to store geodatabases. The ArcSDE database server administrator is responsible for maintaining the database server, creating and maintaining geodatabases, and adding and administering their database server. | Re-use permitted when acknowledging the original Stavros Harizopoulos Daniel Abadi Peter Boncz 2009 Column-Oriented Database Systems Part 1 Stavros Harizopoulos HP Labs Part 2 Daniel Abadi Yale Part 3 Peter Boncz CWI VLDB 2009 Tutorial VLDB 2009 Tutorial Column-Oriented Database Systems 1 Re-use permitted when acknowledging the original Stavros Harizopoulos Daniel Abadi Peter Boncz 2009 What is a column-store row-store column-store Date Store Product Customer Price easy to add modify a record only need to read in relevant data - might read in unnecessary data - tuple writes require multiple accesses suitable for read-mostly read-intensive large data repositories VLDB 2009 Tutorial Column-Oriented Database Systems 2 Re-use permitted when acknowledging the original Stavros Harizopoulos Daniel Abadi Peter Boncz 2009 Are these two fundamentally different 1 The only fundamental difference is the storage layout 1 However we need to look at the big picture different storage layouts proposed row-stores I I II 1 1 I I I I 1 1 I I I I 1 1 row-stores I I II 1 1 I I I I 1 1 I I I I 1 1 row-stores I I II 1 1 I I I I 1 1 I I I I 1 1 70s 80s 90s 00s today new applications new bottleneck in hardware column-stores 1 1 How did we get here and where we are heading What are the column-specific optimizations 1 How do we improve CPU efficiency when operating on Cs Part 3 VLDB 2009 Tutorial Column-Oriented Database Systems
