Database Designer in HP Vertica 7

With the HP Vertica 7, you can use Database Designer with Management Console. As in previous releases, you can still run Database Designer from Admin Tools, but its integration with Management Console offers an additional easy-to-use method for creating a database design.

Database Designer optimizes query performance and minimizes the disk storage that the database uses. It does this by analyzing your logical schema, sample data, and, optionally, your sample queries. Then, Database Designer creates a physical schema design (a set of projections) that can be deployed automatically or manually.

Check out the following demo to get started with the new Database Designer feature in Management Console.

Viewing Query Plans and Profile Data in Management Console 7

With HP Vertica 7.0, Management Console offers a new way to visualize your query plans and get profile information about your queries.

Can Vertica Climb a Tree?

big_basin_0939_mg_1143

The answer is YES if it is the right kind of tree. Here “tree” refers to a common data structure that consists of parent-child hierarchical relationship such as an org chart. Traditionally this kind of hierarchical data structure can be modeled and stored in tables but is usually not simple to navigate and use in a relational database (RDBMS). Some other RDBMS (e.g. Oracle) has a built-in CONNECT_BY function that can be used to find the level of a given node and navigate the tree. However if you take a close look at its syntax, you will realize that it is quite complicated and not at all easy to understand Read More »
