YOUR ALGORITHM

Use NAV to create an algorithm to process your data exactly the way you want with total control for extreme performance and efficiency. You can use any algorithm – including hundreds of existing graph algorithms. NAV also gives you automatic behaviors that make writing code easy and intuitive.

  NAVIGATION

Use NAV to navigate from record to record and table to table using a wide variety of techniques, such as:

• Using an index to look up a record.
• Using a record position to jump directly to a record.
• Moving to next or previous records in index or data order.
• Embedding record positions in records and using them to quickly walk a hierarchy or process a graph of records without index lookups.
• Using foreign keys to join records.
• Filtering records server side for fast bulk retrieval, inserts, updates, and deletes.
• Etc.

  POSITIONS

Use NAV to save and restore multiple record positions to instantly retrieve records or move a cursor to any record – without index lookups. With NAV, record positions can be immutable, making them safe to store inside records as “pointers” to other records. This makes graph traversal easy and fast.

  LOCKS

Use NAV to control if and how a record gets locked automatically or manually. You can combine automatic and manual locks for ease of use and total control. For locking records manually, you can use read, write, blocking, non-blocking, and exclusive locks. For automatically locking records while your application navigates records, use session lock modes, such as no locks, read-only locks, read-write locks, blocking locks, non-blocking locks, etc. You can suspend and resume automatic locking at any time and easily release all or some locks created by your session. You have the ability to freely intermingle SQL and NAV because locks are compatible across both.

  TRANSACTIONS

With NAV you have the ability to create all-or-nothing, isolated transactions that span multiple operations across many records, such as removing an amount from a debit record and adding it to a credit record. You can control when transactions begin, end, are nested, and whether specific records participate in a transaction. NAV allows you to create save points along the way and roll back to them as desired. NAV’s automatic transactions make ACID-compliant navigation easy, and NAV’s manual transactions provide total control to achieve extreme performance and any degree of consistency from eventually consistent to ACID compliance. You can also freely intermingle SQL and NAV because transactions are compatible across both.
