Standards

✅ - At least one insight covers this

❌ - Nothing covers this

🛠️ - This standard has no objectives yet

❌ Use the MongoDB interactive JavaScript Shell

  1. ❌ Use the mongo command to start the shell
  2. ❌ Use either the quit() or exit command to leave the shell
  3. ❌ Use the help command to list command line options

❌ Create and modify a database

  1. ❌ Use the use command to create a new database
  2. ❌ Use the use command to switch to an existing database
  3. ❌ Use the show command to list all created databases with at least one document
  4. ❌ Use the db command to display which database you're currently on
  5. ❌ Use the dropDatabase() method to delete an existing database

❌ Use commands and methods to create, read, update and delete documents within a single collection

  1. ❌ Use the insert() method to create a new document or documents within an existing or new collection
  2. ❌ Use the insertOne() method to add a single new document within an existing or new collection
  3. ❌ Use the insertMany() method to add multiple new documents within an existing or new collection
  4. ❌ Use the find() method to find a specific document located within a collection
  5. ❌ Use the find() and limit method to list an exact number of documents within a collection
  6. ❌ Use the update() method to modify or replace a single or multiple documents within a collection
  7. ❌ Use the updateOne() method to modify a single document within a collection
  8. ❌ Use the updateMany() method to modify multiple documents within a collection
  9. ❌ Use the replaceOne() method to replace a single document within a collection
  10. ❌ Use the deleteOne() method to delete a single document within a collection
  11. ❌ Use the deleteMany() method to delete a single, multiple or all documents within a collection
  12. ❌ Use the remove() method to remove a single, multiple or all documents within a collection
  13. ❌ Use the createCollection() method to create a new collection within the current database
  14. ❌ Use the show collection command to display all available collections within the current database
  15. ❌ Use the drop() method to delete a collection within the current database
  16. ❌ Use the find() and sort method to sort documents within a collection in a specified way
  17. ❌ Use the save() method to either replace an existing document or add a new document to a collection
  18. ❌ Use the renameCollection() method to rename a collection
  19. ❌ Use the findOneAndUpdate() method to find the first document matching the specified criteria and update its content
  20. ❌ Use the findOneAndReplace() method to find the first document matching the specified criteria and replace it with a newly specified one
  21. ❌ Use the findOneAndModify()method to find the first document matching the specified criteria and modify it
  22. ❌ Use projection to include or exclude fields from the output of the query
  23. ❌ Use the Remove() method to delete the first document matching the specified criteria
  24. ❌ Use the findOneAndDelete() method to delete the first document matching the specified criteria

❌ Use a variety of aggregation operations to process data and return the result in a single document

  1. ❌ Use the aggregate() method to look through multiple documents and return a computed result
  2. ❌ Use the $limit aggregation stage to limit the amount of documents to return
  3. ❌ Use the $count aggregation stage to count the number of documents within a collection
  4. ❌ Use the $sort aggregation stage to sort documents in a specific order
  5. ❌ Use the $skip aggregation stage to skip a specific number of documents starting from the first one
  6. ❌ Use the $match aggregation stage to match documents in a specified way
  7. ❌ Use the $group aggregation stage to group documents together
  8. ❌ Use the $project aggregation stage to include or exclude documents from the aggregation pipeline
  9. ❌ Use accumulators related to the $group stage to group documents and perform different calculations
  10. ❌ Use the $sortByCount aggregation stage to group and sort documents by a specified expression

❌ Use field update operators to update documents in various ways

  1. ❌ Use the $set operator to set a new value for a specified field
  2. ❌ Use the $inc operator to either increment or decrement the value of a specified field

❌ Use different comparison operators to perform better queries

  1. ❌ Use $gt to match values that are greater than the specified value.
  2. ❌ Use $gte to match values that are greater than or equal to the specified value.
  3. ❌ Use $lt to match values that are less than the specified value.
  4. ❌ Use $lte to match values that are less than or equal to the specified value.
  5. ❌ Use $in to match any value specified in an array.
  6. ❌ Use $ne to match values that are not equal to a specified value.
  7. ❌ Use $eq to match values that are equal to a specified value.
  8. ❌ Use $nin to match none of the values specified in an array.

❌ Use different logical operators to perform better queries

  1. ❌ Use the $and operator to join 2 or more clauses together with a logical AND, and return all documents that match all of the specified expressions
  2. ❌ Use the $or operator to join 2 or more clauses together with a logical OR, and return all documents that match at least one of the specified expressions
  3. ❌ Use the $nor operator to join 2 or more clauses together with a logical NOR, and return only documents that don't match all of the specified expressions
  4. ❌ Use the $not operator to invert the effect of the query.

Aspects

Given the insights are tagged with aspects, we can filter over the linear content progression and create learning sub-paths.

These sub-path progressions will most likely not cover all content, but they will ensure and enforce an unified learning experience, tailor for the user wish.

For example, a user might be interested in new additions and updates of a language, rather than introduction lessions. Note that these sub-paths don't take games into consideration
