Sorting Databases

December 7, 2009

Last time in information systems we looked at sorting databases. Databases are very efficient at searching and sorting large amounts of data. The ways that a database can sort (which we know so far) is either ascending or descending, this means that the data will either be from A-Z (ascending) or Z-A (descending) in numeric this is 1-9 (ascending) or 9-1 (descending). When sorting ONE field this is a simple sort, when sorting TWO OR MORE fields then it is a complex sort.

Here is a video on how to sort mulitple fields, this is in Microsoft Access but the functions are pretty much the same compared with Filemaker Pro.

Data Dictionaries Contin.

November 23, 2009

For the past three days(17th-19th) in Information Systems we have been looking at Data Dictionaries.

We started thinking about inserting multimedia in databases such as images, sound or even a video.
