Companies can't remove reviews or game the system. Here's why
Teradata is used throughout the entire company. It is used to store and query a vast amount of data. We store almost all of our membership, claims, revenue, etc. in this application. Many reports utilize this application to easily compile data which can then be used in other applications to properly display and report findings
- Stores large amount of data.
- The syntax used is easy to learn.
- Makes it easy to import and export your own data.
- Sometimes it isn’t clear the reason an error will occur in the query. More detailed responses would be helpful
- It can be slow at times when pulling large data amounts
- Sometimes spool space will run out when trying to run certain queries
Teradata is most suited when needing to get data for a specific purpose. If you need to report data and display it, this application is not as well suited. It should only be used to store and access data. It does a good job of organizing the data. You can get your dataset at a place where little to no additional tweaking would be needed in other applications.
Our company uses Teradata to merge various departments across the whole organization. With data coming from many source systems, we are able to use Teradata to enhance our Business Intelligence practices and provide our executives with next-day reporting. Merged data includes sales, customer care, product inventory, and field technician performance.
- Can query multiple databases within one server and view all results in one window. Helps speed up analysis.
- Teradata uses AMPs (Access Module Processors) to increase speed of data processing/queries. You must use 'COLLECT STATISTICS' properly to efficiently use the AMPs.
- Most standard SQL practices work on Teradata. Also, Teradata formats the query in a nice colored structure.
- Can search for tablenames or specific columnnames across the entire server. Helps when changing a specific column or table structure.
- Errors on compiling a procedure are sometimes hard to decipher. Teradata provides a line number of the error but this number does not always match the line number of the procedure in the query window.
- Teradata won't run a query if I copy and paste from my internal company chat. Something with the formatting from the chat creates a syntax error, so I have to take time to rewrite the query.
- I haven't been able to insert multiple new rows into a table with 1 insert. Other SQL programs allow this with a comma, but Teradata makes you create separate inserts for each row.
It is highly applicable for large, corporate companies with data coming from multiple sources. Teradata can be used as an ODS (Operational Data Store) to merge the source data, then it can also be used to create development/UAT databases, and production databases under the same server. It is capable of processing billions of records per day. It is less appropriate for companies with a single source of data.
