Kwanan nans days aka sanar da labarin kaddamar da aikin FerretDB, (wanda ake kira MangoDB), wanda ke ba ku damar maye gurbin DBMS na tushen daftarin aiki na MongoDB tare da PostgreSQL ba tare da yin wani canje-canje ga lambar aikace-aikacenku ba.
An aiwatar da FerretDB azaman uwar garken wakili wanda ke fassara kira zuwa MongoDB cikin tambayoyin SQL zuwa PostgreSQL, yana ba ku damar amfani da PostgreSQL azaman maajiyar gaske.
FerretDB (tsohuwar MangoDB) an kafa shi don zama tushen abin da zai maye gurbin MongoDB. FerretDB wakili ne na buɗaɗɗen tushe wanda ke canza tambayoyin yarjejeniya ta waya ta MongoDB zuwa SQL, ta amfani da PostgreSQL azaman injin bayanai.

A cikin sakin FerretDB 0.1.0 an lura cewa gaba daya an sake fasalin hanyar da aka dawo da bayanan PostgreSQL. A baya can, ga kowane buƙatun MongoDB mai shigowa, an samar da tambayar SQL zuwa PostgreSQL, ta amfani da ayyuka don aiki tare da tsarin JSON da tace sakamakon a gefen PostgreSQL.
