Trusted MongoDB Coders, Developers for Hire in Ukraine

MongoDB is a document-based database management system (DBMS) with open source code that does not require a description of the table schema. It is classified as NoSQL, uses JSON-like documents and a database schema. Written in C ++. Requests can return specific document fields and custom JavaScript functions. Regular expression search is supported. You can also configure the request to return a random result set. MongoDB supports indexes. This is scaled horizontally using shading. The user selects the shard key, which determines how the data in the collection will be distributed. The data will be divided into ranges (depending on the shard key) and distributed over shards. Also, the program can work in accordance with the MapReduce paradigm. In the framework for aggregation, there is an analog of the SQL statement GROUP BY. Aggregation operators can be linked into a pipeline like UNIX pipelines. The framework also has a $ lookup operator for binding documents at unloading and statistical operations such as standard deviation.

Questions and Answers related to MongoDB Development

When should I use MongoDB instead of MySQL?

“You should use MongoDB if you don’t care about your data and don’t think you applications data needs will evolve much. If it gets very complex you may find using MongoDB to be a pain to use. You should use MySQL if you don’t care about your data and are willing to work around its quirks. Honestly I would only use either of them if I was working on a system that already used them. There may be some narrow edge cases under which MySQL and MongoDB are good options, but I would never recommend them out of hand.”

When does it become necessary to add Elasticsearch to MongoDB?

“ElasticSearch is optimized for full text search operations, MongoDB is not. When your queries is going like to be text search queries you should better use Elasticsearch or similar server. You don’t need to index all fields in MongoDB, just index the attributes that you will search and use. ElasticSearch has many features and it’s not only for full-text search. You can use your MongoDB as your persistent datastore and elasticsearch for getting a range of records or searching a text…”

What is MongoDB good for?

“I would say that MongoDB or other non-relational data stores are inadequate if you want your DBMS to prevent data integrity error or data anomalies. Non-relational stores encourage storing denormalized data, which means redundant data, and that leads to data integrity problems. Some people advocate solving this by enforcing data integrity in application code, whereas most SQL databases enforce constraints in the DBMS. Using DBMS constraints is preferable if you have a variety of different applications reading and writing your data…”

How do we evaluate CRUD operations in MongoDB? Why it is quoted that NoSQL is faster than SQL in most cases?

“If you want to see which query plan MongoDB has chosen for a particular operation, like query(), try cursor.explain() – MongoDB Manual 3.4. This is pretty similar to the explain plans in relational engines, in that it shows you how the db engine is going to actually perform your query — which indexes were used, and the like. See Explain Results – MongoDB Manual 3.4 for more…”
